List of extinct bird species since 1500

===Paleognathes=== ====Apterygiformes==== The kiwis of New Zealand • West Coast spotted kiwi, Apteryx occidentalis (South Island, New Zealand, c. 1900) • :A doubtfully distinct species; may be a subspecies of the little spotted kiwi (Apteryx owenii) or a hybrid between that species and the Okarito kiwi (Apteryx rowi). ===Anseriformes=== Ducks, geese and swans • Anatidaeducks, geese and swans • Anatinaeducks • Tadornini • Extinct species of extant genera • Tadornashelducks • Crested shelduck, Tadorna cristata (Northeast Asia, 1964) • :A likely relict species from Northeast Asia. Officially critically endangered due to unconfirmed reports made between 1985 and 1990 and poor survey coverage of the regions. Poorly known; observed in 1672, declared extinct in 1710. • Mauritius sheldgoose, Alopochen mauritianus (Mauritius, Mascarenes, 1693) Last reported in 1693, declared extinct in 1698. • Merginisea ducks • †CamptorhynchusLabrador duck • Labrador duck, Camptorhynchus labradorius (northeastern North America, c. 1878)Possibly a relict species. Causes of extinction are poorly known, but at least partly driven by hunting. • Extinct species of extant genera • Mergusmergansers • Auckland Island merganser, Mergus australis (New Zealand and the Auckland Islands, Southwest Pacific, c. 1902) Driven to extinction by predation by introduced mammals and hunting. • Aythyinidiving ducks • Extinct species of extant genera • Chenonetta • Finsch's duck, Chenonetta finschi (New Zealand, c. 1760) • :Causes of extinction included predation by rats and overhunting. • Rhodonessapink-headed duck • Pink-headed duck, Rhodonessa caryophyllacea (East India, Bangladesh, North Myanmar, c. 1945)sometimes included in genus Netta, but this classification is not generally accepted. • :Population declined sharply in early 20th century due to habitat loss and hunting. • :Undescribed extinct species only known from two subfossils and two historical reports (1687, 1710) of non-Mascarene teal ducks on Réunion. • Anatinidabbling ducks • Extinct species of extant genera • Marecawigeons • Amsterdam wigeon, Mareca marecula (Amsterdam Island, South Indian Ocean, 1793) Driven to extinction by habitat destruction, hunting, and the introduction of invasive species. • Anas • Saint Paul Island duck, Anas sp. (St. Paul Island, South Indian Ocean, c. 1800) • : Only known by a single report from 1793. May be synonymous with the Amsterdam wigeon or a distinct species or subspecies. • Mascarene teal, Anas theodori (Mauritius and Réunion, Mascarenes, 1710) • Mariana mallard, Anas oustaleti (Marianas, West Pacific, 1981) – often considered a subspecies of the mallard (Anas platyrhynchos) or a hybrid with the Pacific black duck (Anas superciliosa) Hunting and habitat loss were both responsible for extinction. Captive breeding conservation efforts were unsuccessful.) • :May have survived to the late 18th century, as evidenced by descriptions of the bird named "Tetrao australis" and later "Megapodius andersoni". • Viti Levu scrubfowl, Megapodius amissus (Viti Levu and possibly Kadavu, Fiji, 20th century?) • :Only concretely known from subfossils dating 2900-2700 years before present. Likely driven to extinction by hunting. Unconfirmed sightings from the 20th century. • Raoul Island scrubfowl, Megapodius sp. (Raoul, Kermadec Islands, 1876) • :A hypothetical species said to have inhabited Raoul Island until the population was wiped out in a volcanic eruption. It is not clear whether the birds represent a distinct taxon. • Phasianidaepheasants and allies • Extinct species of extant genera • Coturnix • New Zealand quail, Coturnix novaezelandiae (New Zealand, 1875) Causes of extinction involved introduced diseases, competition with invasive species, and agricultural burning. • :Last confirmed sighting in 1876. Officially critically endangered due to ongoing unconfirmed sightings and sparse survey coverage in the historical range. Reasons for decline and possible extinction not well known, but may include hunting and habitat destruction. ===Podicipediformes=== Grebes • Extinct species of extant genera • Tachybaptus • Alaotra grebe, Tachybaptus rufolavatus (Lake Alaotra and surrounding lakes, Madagascar, 1985) • :Officially declared extinct in 2010, 25 years after the last official sighting in 1985. Its extinction was primarily due to habitat destruction, the introduction of invasive and hybridisation with the little grebe (Tachybaptus ruficollis). • Podilymbus • Atitlán grebe, Podilymbus gigas (Lake Atitlán, Guatemala, 1989) Extinction driven by habitat destruction, an earthquake-driven drop in lake level in 1976, and hybridization with the Pied-billed grebe (Podilymbus podiceps). • Podiceps • Colombian grebe, Podiceps andinus (Bogotá area, Colombia, 1977) Population rapidly declined beginning in the 1950s due to factors including habitat destruction, the introduction of carnivorous trout, hunting, and water pollution. Extensive surveys in the 1980s failed to observe any individuals. ===Charadriiformes=== (Pinguinus impennis), the Natural History Museum, London, England Shorebirds, gulls and auks • Haematopodidaeoystercatchers • Extinct species of extant genera • Haematopusoystercatchers • Canary Islands oystercatcher, Haematopus meadewaldoi (eastern Canary Islands, East Atlantic, c. 1940s) • :Last confirmed sighting from 1913, reported extinct in 1940s. Extinction likely driven by overharvesting by humans of intertidal zone, habitat destruction, and introduced predators. • Charadriidaeplovers and lapwings • Extinct species of extant genera • Vanelluslapwings • Javan lapwing, Vanellus macropterus (Java, Indonesia, mid-20th century) • :Last recorded in 1940. Decline and possible extinction driven by hunting and habitat destruction. • Eua rail, Gallirallus vekamatolu • :Known from prehistoric bones found on Eua. It was probably a close relative of the Vava'u rail. • Tongatapu rail, Gallirallus hypoleucus (Tongatapu, Tonga, Southwest Pacific, late 18th or 19th century) • Hiva Oa rail, Gallirallus sp. • Norfolk Island rail, Gallirallus sp. (Norfolk Island, Southwest Pacific, early 17th century?) • :May be the bird shown on a bad watercolor illustration made about 1800. • Chatham rail, Cabalus modestus (Chatham Islands, Southwest Pacific, c. 1900) • New Caledonian rail, Cabalus lafresnanayanus (New Caledonia, Melanesia, c. 1900?) • :Officially classified as critically endangered, the last records were in 1984 and it seems as if all of the available habitat has now been overrun by feral pigs and feral dogs, which preyed on this bird. • Ascension crake, Mundia elpenor (Ascension Island, South Atlantic, late 17th century)formerly Atlantisia • Saint Helena crake, Zapornia astrictocarpus (St. Helena, South Atlantic, early 16th century) • Laysan rail, Zapornia palmeri (Laysan, Hawaiian Islands, 1944) • Hawaiian rail, Zapornia sandwichensis (Big Island, Hawaiian Islands, c. 1890) • Kosrae crake, Zapornia monasa (Kosrae, Carolines, c. mid-to-late 19th century) • Tahiti crake, Zapornia nigra (Tahiti, Society Islands, South Pacific, c. 1800) • :Known only from paintings and descriptions; its taxonomic status is uncertain, as the material is often believed to refer to the extant spotless crake (Zapornia tabuensis). • Saint Helena rail, Aphanocrex podarces (St. Helena, South Atlantic, 16th century)formerly Atlantisia • White swamphen, Porphyrio albus (Lord Howe Island, Southwest Pacific, early 19th century) • Réunion swamphen or oiseau bleu, Porphyrio coerulescens (Réunion, Mascarenes, 18th century) • :Known only from descriptions. The former existence of a Porphyrio on Réunion is fairly certain, but it has not been proven to date. • Marquesas swamphen, Porphyrio paepae (Hiva Oa and Tahuata, Marquesas) • :May have survived to c. 1900. In the lower right hand corner of Paul Gauguin's 1902 painting ''Le Sorcier d'Hiva Oa ou le Marquisien à la cape rouge, there is a bird which resembles native descriptions of P. paepae''. • North Island takahē, Porphyrio mantelli (North Island, New Zealand, late 19th century) • :Known from subfossil bones found in New Zealand's North Island; may have survived to 1894 or later. • New Caledonian gallinule, Porphyrio kukwiedei (New Caledonia, Melanesia) • :May have survived into historic times. The native name ''n'dino'' is thought to refer to this bird. • Samoan woodhen, Gallinula pacifica (Savaii, Samoa, 1907?) • :Probably better placed in the genus Pareudiastes. Unconfirmed reports from the late 20th century suggest it still exists in small numbers and therefore it is officially classified as critically endangered. • Makira woodhen, Gallinula silvestris (Makira, Solomon Islands, mid-20th century?) • :Only known from a single specimen, this rail is probably better placed in its own genus, Edithornis. Unconfirmed recent records suggest it still exists and therefore it is officially classified as critically endangered. • Tristan moorhen, Gallinula nesiotis (Tristan da Cunha, South Atlantic, late 19th century) • Mascarene coot, Fulica newtonii (Mauritius and Réunion, Mascarenes, c. 1700) • Sharpe's rail, Gallirallus sharpei (Indonesia?) • :Only known from a type specimen, but scientist speculate that it originated form Indonesia. Could possibly be a colour morph of the buff-banded rail. • Fernando de Noronha rail, Rallidae gen. et sp. indet. (Fernando de Noronha, West Atlantic, 16th century?) • :A distinct species of rail inhabited Fernando de Noronha Island, but it has not been formally described yet. It probably still existed at the time of the first Western contact. • Tahitian "goose", Rallidae gen. et sp. indet. (Tahiti, Society Islands, South Pacific, late 18th century?) • :Early travelers to Tahiti reported a "goose" that was found in the mountains. Altogether, a species of rail in the genus Porphyrio seems to be the most likely possibility. • Bokaak "bustard", Rallidae? gen. et sp. indet. 'Bokaak' • :An unidentified terrestrial bird is mentioned in an early report from Bokaak in the Marshall Islands. It was described as a "bustard" and may have actually been a rail or a megapode. In the former case, it may have been a vagrant of a still-existing species; in any case, no bird that could be described as "bustard-like" is found on Bokaak today. • Rallidae gen. et sp. indet. 'Amsterdam Island' • :Unknown rail from Amsterdam Island; one specimen was found, but it was not recovered. Extinct by 1800, it may have been a vagrant of a still-existing species. ===Procellariiformes=== Petrels, storm petrels, shearwaters and albatrosses • Olson's petrel, Bulweria bifax (St. Helena, South Atlantic, early 16th century) • Saint Helena petrel, Pseudobulweria rupinarum (St. Helena, South Atlantic, early 16th century) • Imber's petrel, Pterodroma imberi (Chatham Islands, Southwest Pacific, early 19th century?) • :Described from subfossil bones. • Jamaican petrel, Pterodroma caribbaea (Jamaica, West Indies, late 19th century?) • :Possibly a subspecies of the black-capped petrel (Pterodroma hasitata); unconfirmed reports suggest it may still exist. Officially classified as critically endangered, possibly extinct. • Pterodroma cf. leucoptera (Mangareva, Gambier Islands, South Pacific, 20th century?) • :A wing of a petrel carcass that was similar in appearance to Gould's petrel (Pterodroma leucoptera) was recovered on Mangareva in 1922, where it possibly bred. No such birds are known to exist there today. • Guadalupe storm petrel, Hydrobates macrodactylus (Guadalupe Island, East Pacific, 1910s) • :Officially classified as critically endangered, possibly extinct, but a thorough survey in 2000 concluded this species was certainly extinct. ===Sphenisciformes=== Penguins • Extinct species of extant genera • Eudyptescrested penguins • Chatham penguin, Eudyptes warhami (Chatham Islands, Southwest Pacific, between 1867 and 1872?) • :Only known from subfossil bones, but a bird kept in captivity sometime between 1867 and 1872 may refer to this species. ===Suliformes=== Boobies and related birds • Sulidaegannets and boobies • Mascarene booby, Papasula sp. (Mauritius and Rodrigues, Mascarenes, mid-19th century) • An undescribed booby species that was formerly considered a population of Abbott's booby (Papasula abbotti). Known physically only from subfossil bones, but is likely the bird referred to as a boeuf by early settlers; the boeuf was last recorded on Rodrigues in 1832 and likely went extinct following the deforestation of the island. • Phalacrocoracidaecormorants and shags • Spectacled cormorant, Urile perspicillatus (Commander Islands, North Pacific, c. 1850) ===Pelecaniformes=== Pelicans and related birds • Threskiornithidaeibises and spoonbills • Extinct species of extant genera • Threskiornis • Réunion ibis, Threskiornis solitarius (Réunion, Mascarenes, early 18th century) • :This species was the basis for the "Réunion solitaire" or "white dodo" ("Raphus solitarius"), a supposed relative of the dodo and the Rodrigues solitaire. Given the fact that ibis (but no dodo-like) bones were found on Réunion and that old descriptions match a flightless sacred ibis quite well, the "Réunion solitaire" hypothesis has been refuted. • Ardeidaeherons, egrets, and bitterns • Botaurinaebitterns • Extinct species of extant genera • Botaurus • New Zealand bittern, Botaurus novaezelandiae (New Zealand, late 19th century) • :Long considered to be vagrant individuals of the Australian little bittern (Botaurus dubius); bones recovered from Holocene deposits indicate that this was indeed a distinct taxon, but it may not be a distinct species. • Ardeinaeherons and egrets • Extinct species of extant genera • Nyctanassa • Bermuda night heron, Nyctanassa carcinocatactes (Bermuda, West Atlantic, 17th century) • :Sometimes assigned to the genus Nycticorax. • Nycticorax • Réunion night heron, Nycticorax duboisi (Réunion, Mascarenes, late 17th century) • Mauritius night heron, Nycticorax mauritianus (Mauritius, Mascarenes, c. 1700) • Rodrigues night heron, Nycticorax megacephalus (Rodrigues, Mascarenes, mid-18th century) • Ascension night heron, Nycticorax olsoni (Ascension Island, South Atlantic, late 16th century?) • :Known only from subfossil bones, but the description of a flightless Ascension Island bird by André Thévet cannot be identified with anything other than this species. ===Columbiformes=== Pigeons, doves and dodos For the "Réunion solitaire", see Réunion ibis. • †EctopistesPassenger pigeon • Passenger pigeon, Ectopistes migratorius (eastern North America, 1914) • :The passenger pigeon was once among the most abundant wild bird species in the world, with a single flock numbering up to 2.2 billion birds. It was hunted close to extinction for food and sport in the late 19th century. The last individual, a mateless female named Martha after Martha Washington, died in the Cincinnati Zoo in 1914. • †DysmoropeliaSaint Helena dove • Saint Helena dove, Dysmoropelia dekarchiskos (St. Helena, South Atlantic, 16th century?) • :Known only from Late Pleistocene bones, but may have persisted until the 16th century. • †RaphusDodo • Dodo, Raphus cucullatus (Mauritius, Mascarenes, late 17th century) • :Called Didus ineptus by Linnaeus. A metre-high flightless bird found on Mauritius. Its forest habitat was destroyed when Dutch settlers moved to the island and the dodo's nests and eggs were destroyed by the pigs, cats and monkeys that the Dutch brought with them. The last specimen was killed in 1681, only 80 years after the arrival of the new predators. • †PezophapsRodrigues solitaire • Rodrigues solitaire, Pezophaps solitaria (Rodrigues, Mascarenes, c. 1730) • Extinct species of extant genera • Bonin wood pigeon, Columba versicolor (Nakodo-jima and Chichi-jima, Ogasawara Islands, c. 1890) • Ryukyu wood pigeon, Columba jouyi (Okinawa and Daito Islands, Northwest Pacific, late 1930s) • Rodrigues pigeon, Nesoenas rodericanus (Rodrigues, Mascarenes, before 1690?) • :Formerly in Streptopelia. Possibly a subspecies of the Malagasy turtle dove (Nesoenas picturatus), this seems to be the bird observed by Leguat. Introduced rats may have caused it to become extinct in the late 17th century. • Spotted green pigeon, Caloenas maculata (South Pacific or Indian Ocean islands, 1820s) • :Also known as the Liverpool pigeon, the only known specimen has been in Liverpool's World Museum since 1851, and was probably collected on a Pacific island for Edward Stanley, 13th Earl of Derby. It has been suggested that this bird came from Tahiti based on native lore about a somewhat similar extinct bird called the titi, but this has not yet been verified. • Sulu bleeding-heart, Gallicolumba menagei (Tawitawi, Philippines, late 1990s?) • :Officially classified as critically endangered. Only known from two specimens taken in 1891. There have been a number of unconfirmed reports from all over the Sulu Archipelago in 1995; however, these reports stated that the bird had suddenly undergone a massive decline and, by now, habitat destruction is almost complete. If it is not extinct, this species is certainly very rare, but the ongoing civil war prevents comprehensive surveys. • Norfolk ground dove, Pampusana norfolciensis (Norfolk Island, Southwest Pacific, c. 1800) • Tanna ground dove, Pampusana ferruginea (Tanna, Vanuatu, late 18th or 19th century) • :Only known from descriptions of two now-lost specimens. • Thick-billed ground dove, Pampusana salamonis (Makira and Ramos, Solomon Islands, mid-20th century?) • :Last recorded in 1927, only two specimens exist. Declared extinct in 2005. • Choiseul pigeon, Microgoura meeki (Choiseul, Solomon Islands, early 20th century) • Red-moustached fruit dove, Ptilinopus mercierii (Nuku Hiva and Hiva Oa, Marquesas, 1922) • :Two subspecies, the little-known nominate subspecies P. m. mercierii of Nuku Hiva (extinct mid- to late 19th century) and P. m. tristrami of Hiva Oa (1922). • Negros fruit dove, Ptilinopus arcanus (Negros, Philippines, late 20th century?) • :Known only from one specimen taken at the only documented sighting in 1953; the validity of this species has been questioned, but no good alternative to distinct species status has been proposed. Officially classified as critically endangered, it may still exist on Panay, but no survey has located it. One possible record in 2002 does not seem to have been repeated since then. • Mauritius blue pigeon, Alectroenas nitidissima (Mauritius, Mascarenes, c. 1830s) • Réunion blue pigeon, Alectroenas sp. (Réunion, Mascarenes, 1619) • Providence blue pigeon, Alectroenas sp. (Farquhar Group, Seychelles, 19th century) • :Only known from early reports; possibly a subspecies of either the Comoros blue pigeon (Alectroenas sganzini) or the Seychelles blue pigeon (Alectroenas pulcherrimus). • Mauritian turtle dove, Nesoenas cicur (Mauritius, Mascarenes, 1730s) • :Similar to the Malagasy turtle dove but more terrestrial, with more robust legs and smaller wings. Disappeared by 1730 due to hunting, predation by introduced mammals, and deforestation. • Mauritian wood pigeon, Columba thiriouxi (Mauritius, Mascarenes, 1730s) • :Described from subfossil remains, it is believed to have become extinct by 1730 due to hunting, predation by introduced black rats, and deforestation. The species has been questioned due to the material being scarce and not completely distinguishable from rock doves introduced to the island in 1639. However, early historical accounts mention the existence of pigeons that were caught with ease. ===Cuculiformes=== Cuckoos • †NannococcyxSaint Helena cuckoo • Saint Helena cuckoo, Nannococcyx psix (St. Helena, South Atlantic, 18th century) • Extinct species of extant genera • Couacouas, a genus endemic to Madagascar • Delalande's coua, Coua delalandei (Madagascar, late 19th century?) ===Cathartiformes=== New World vultures • "Painted vulture", Sarcoramphus sacra (Florida, North America, late 18th century?) • A bird supposedly similar in appearance to the king vulture (Sarcoramphus papa) identified by William Bartram on his travels in the 1770s. Skeptics have stated that it is likely based on a misidentification of the crested caracara (Caracara plancus), although evidence has increasingly shifted towards it being a valid taxon that once existed, either as a distinct species in its own right or as a subspecies of the king vulture, based on an independent illustration of a nearly identical bird made several decades earlier by Eleazar Albin. See the King vulture article for discussion. ===Strigiformes=== True owls and barn owls Strigidaetrue owls • Pernambuco pygmy owl, Glaucidium mooreorum (Pernambuco, Brazil, 2001?) • :Officially classified as critically endangered, but it may still exist. A 2018 BirdLife study citing extinction patterns recommended reclassifying this species as possibly extinct. • Réunion scops owl, Otus grucheti (Réunion, Mascarenes, late 17th century?) • Mauritius scops owl, Otus sauzieri (Mauritius, Mascarenes, c. 1850) • Rodrigues scops owl, Otus murivorus (Rodrigues, Mascarenes, mid-18th century) • :The preceding three species were variously placed in the genera Bubo, Athene, "Scops" (=Otus), Strix and Tyto and even in their own genus, Mascarenotus, before their true affinity was realized. • Siau scops owl, Otus siaoensis (Siau Island, Indonesia, 20th century?) • :Only known from the holotype collected in 1866. It may still exist, as there are ongoing rumors of scops owls at Siau. • New Caledonian boobook, Ninox cf. novaeseelandiae (New Caledonia, Melanesia) • :Known only from prehistoric bones, but it may still exist. • Laughing owl, Ninox albifacies (New Zealand, 1914?) • :Two subspecies: the nominate subspecies N. a. albifacies (South Island and Stewart Island, extinct 1914?) and N. a. rufifacies (North Island, extinct c. 1870s?); circumstantial evidence suggests that small remnants survived until the early or mid-20th century. Tytonidaebarn owls • Puerto Rican barn owl, Tyto cavatica (Puerto Rico, West Indies, early 20th century?) • :Known from prehistoric bones found in caves on Puerto Rico; it may have still existed up to 1912, given reports of the presence of cave-roosting owls. Likely a subspecies of, or synonymous with, the still-existing ashy-faced owl (Tyto glaucops). ===Caprimulgiformes=== Caprimulgidaenightjars and nighthawks • Jamaican poorwill, Siphonorhis americana (Jamaica, West Indies, late 19th century?) • :Reports of unidentifiable nightjars from the 1980s in habitat appropriate for this cryptic species suggest that it may still exist. Research into this possibility is currently underway; pending further information, it is officially classified as critically endangered, possibly extinct. • Cuban pauraque, Siphonorhis daiquiri (Cuba, West Indies, prehistoric?) • :Described from subfossil bones in 1985. There are persistent rumors that this bird, which was never seen alive by scientists, may still exist. Compare the Puerto Rican nightjar (Antrostomus noctitherus) and the preceding species. • Vaurie's nightjar, Caprimulgus centralasicus (China, early 20th century?) • :Only known from a single specimen from Xinjiang, China taken in 1929. It has never been seen or found again, but the validity of this supposed species is seriously disputed. It was, however, never refuted to be an immature desert-dwelling female European nightjar (Caprimulgus europaeus). • New Caledonian nightjar, Eurostopodus exsul (New Caledonia, Melanesia, mid-20th century) • :This species was sighted only once in 1939; due to its cryptic habits, it may still be extant, but this is now considered to be unlikely. ===Aegotheliformes=== Aegothelidae • New Caledonian owlet-nightjar, Aegotheles savesi (New Caledonia, late 1990s) • Not to be confused with the New Caledonian nightjar. The type specimen was collected after the bird flew into a bedroom in the village of Tonghoué. This large owlet-nightjar is only known from two specimens taken in 1880 and 1915, two other confirmed sightings and two other partly disputed sightings and one unconfirmed debated sighting. The most recent report is from a 1998 expedition which saw a large nightjar foraging for insects at dusk in Rivière Ni Valley. ===Apodiformes=== Swifts and hummingbirds • Letitia's thorntail, Discosura letitiae (Bolivia?) • :Known only from three trade specimens of unknown origin. It may still exist. • Brace's emerald, Riccordia bracei (New Providence, Bahamas, West Indies, late 19th century) • Gould's emerald, Riccordia elegans (Jamaica or northern Bahamas, West Indies, late 19th century) • Turquoise-throated puffleg, Eriocnemis godini (Ecuador, 20th century?) • :Officially classified as critically endangered, possibly extinct. Known only from six pre-1900 specimens, the habitat where it occurred has been destroyed. However, the bird's distribution remains unresolved. • Guanacaste hummingbird, Saucerottia alfaroana (Miravalles Volcano, Costa Rica) • :A possibly extinct species of hummingbird known only from a holotype collected in 1895 at the Miravalles Volcano in Costa Rica. ===Coraciiformes=== Kingfishers and related birds • Saint Helena hoopoe, Upupa antaois (St. Helena, South Atlantic, early 16th century) • Guam kingfisher, Todirhmphus cinnamominus (Guam, West Pacific, 1986) • :This species became extinct in the wild in 1986 when 29 birds were taken for a captive breeding program, which is still ongoing. Its decline was caused by predation by introduced brown tree snakes. ===Piciformes=== Woodpeckers and related birds • Extinct species of extant genera • Colaptes • Bermuda flicker, Colaptes oceanicus (Bermuda, West Atlantic, 17th century?) • :Known only from fossil bones found in Bermuda and dated to the Late Pleistocene and the Holocene; however, a 17th-century report written by explorer Captain John Smith may refer to this species. • Campephilus • Imperial woodpecker, Campephilus imperialis (Mexico, late 20th century) • :This 60-centimetre-long woodpecker is officially classified as critically endangered, possibly extinct. Occasional unconfirmed reports come up; the most recent was in late 2005. • Ivory-billed woodpecker, Campephilus principalis (southeastern United States and Cuba, late 20th century) • :The nominate subspecies, the American ivory-billed woodpecker (C. p. principalis), is officially classified as critically endangered and considered possibly extinct by some authorities. • :The Cuban ivory-billed woodpecker (C. p. bairdii) is generally considered to be extinct, but a few patches of unsurveyed potential habitat remain. ===Falconiformes=== Birds of prey • Guadalupe caracara, Caracara lutosa (Guadalupe, East Pacific, 1900 or 1903) • Réunion kestrel, Falco duboisi (Réunion, Mascarenes, c. 1700) ===Psittaciformes=== Parrots , the Museum Wiesbaden, Germany • Strigopidaekakas and kakapos • Extinct species of extant genera • Nestor • Chatham kākā, Nestor chathamensis (Chatham Islands, New Zealand, between 1500 and 1650) • Norfolk kākā, Nestor productus (Norfolk and Philip Islands, Southwest Pacific, 1851?) • Psittacidaeparrots, parakeets, and lorikeets • Sinú parakeet, Pyrrhura subandina (Colombia, mid-20th century?) • :This bird has a very restricted distribution and was last reliably recorded in 1949. It was not found during searches in 2004 and 2006 and seems to be extinct; efforts to find it again continue, but are hampered by the threat of armed conflict. • Society parakeet, Cyanoramphus ulietanus (Raiatea, Society Islands, South Pacific, late 18th century) • Black-fronted parakeet, Cyanoramphus zealandicus (Tahiti, Society Islands, South Pacific, c. 1850) • Lord Howe parakeet, Cyanorhamphus subflavescens (Lord Howe Island, Southwest Pacific, c. 1870) • Macquarie parakeet, Cyanorhamphus erythrotis (Macquarie Islands, Southwest Pacific, 1890s) • :Last recorded in 1890 and not found by surveys in 1894. • Paradise parrot, Psephotellus pulcherrimus (Rockhampton area, Australia, late 1920s) • Oceanic eclectus, Eclectus infectus, known from subfossil bones found on Tonga, Vanuatu, and possibly Fiji, may have survived until the 18th century or even longer: a bird which seems to be a male Eclectus parrot was drawn in a report on the Tongan island of Vavau by the Malaspina expedition. Also, a 19th-century Tongan name āā ("parrot") for "a beautiful bird found only at Eua" is attested (see here under "kākā"). This seems to refer to either E. infectus, which in Tonga is only known from Vavau and Eua, or the extirpated population of the collared lory (Vini solitaria), which also occurred there. It is possible, but unlikely, that this species survived on Eua until the 19th century. • New Caledonian lorikeet, Vini diadema (New Caledonia, Melanesia, mid-20th century?) • :Officially classified as critically endangered, there have been no reports of this species since the mid-20th century. It is, however, small and inconspicuous and is likely to have been overlooked. • Seychelles parakeet, Psittacula wardi (Seychelles, West Indian Ocean, 1883) • Newton's parakeet, Psittacula exsul (Rodrigues, Mascarenes, c. 1875) • Mascarene grey parakeet, Psittacula bensoni (Mauritius, possibly Réunion as Psittacula cf. bensoni, 1760s). • :Formerly known as the Mauritius grey parrot (Lophopsittacus bensoni). Known from a 1602 sketch by Captain Willem van Westzanen and by subfossil bones described by David Thomas Holyoak in 1973. It may have survived into the mid-18th century. • Mascarene parrot, Mascarinus mascarinus (Réunion and possibly Mauritius, Mascarenes, 1834?) • :The last known individual was a captive bird which was alive before 1834. • Broad-billed parrot, Lophopsittacus mauritianus (Mauritius, Mascarenes, 1680?) • :It may have survived into the late 18th century. • Rodrigues parrot, Necropsittacus rodericanus (Rodrigues, Mascarenes, late 18th century) • :The species N. francicus is fictional, N. borbonicus is most likely so. • Glaucous macaw, Anodorhynchus glaucus (northern Argentina, early 20th century) • :Officially classified as critically endangered due to persistent rumors of wild birds, but probably extinct. • Cuban macaw, Ara tricolor (Cuba, late 19th century) • :A number of related macaw species have been described from the West Indies, but are not based on good evidence. Several prehistoric forms are now known to have existed in the region, however. • Carolina parakeet, Conuropsis carolinensis (southeastern North America, c. 1930?) • :Although the date of the last captive bird's death in the Cincinnati Zoo, 1918, is generally given as this species' date of extinction, there are convincing reports of some wild populations persisting until later. Two subspecies, C. c. carolinensis (Carolina parakeet, east and south of the Appalachian Mountainsextinct either 1918 or c. 1930) and C. c. ludovicianus (Louisiana parakeet, west of the Appalachian Mountainsextinct c. 1912). • Guadeloupe parakeet, Psittacara labati (Guadeloupe, West Indies, late 18th century) • :Only known from descriptions; the former existence of this bird is likely both for biogeographic reasons and because details about it as described cannot be referred to any known species. • Puerto Rican parakeet, Psittacara maugei (Mona Island and possibly Puerto Rico, West Indies, 1890s) • :Formerly considered to be a weakly differentiated subspecies of the still-existing Hispaniolan parakeet (Psittacara chloropterus). • Martinique amazon, Amazona martinica (Martinique, West Indies, mid-18th century) • Guadeloupe amazon, Amazona violacea (Guadeloupe, West Indies, mid-18th century) • :These two extinct amazons were originally described from travelers' descriptions.

Unconfirmed records exist from the early to mid-1950s. • The identity of "Strigiceps leucopogon" (an invalid name) described by Lesson in 1840 is unclear. Apart from the holotype supposedly from "New Holland", a second specimen from the "Himalaya" either may have existed or may still exist. Lesson tentatively allied it to the Meliphagidae, and Rothschild felt reminded of the kioea. Acanthizidaescrubwrens, thornbills, and gerygones • Lord Howe gerygone, Gerygone insularis (Lord Howe Island, Southwest Pacific, c. 1930) Pachycephalidaewhistlers, shrike-thrushes, pitohuis and allies • Mangarevan whistler, ?Pachycephala gambierana (Mangareva, Gambier Islands, South Pacific, late 19th century?) • :Tentatively placed here. A mysterious bird of which no specimens exist today. It was initially described as a shrike, then classified as an Eopsalteria "robin" and may actually be an Acrocephalus warbler. Dicruridaemonarch flycatchers and allies • Maupiti monarch, Pomarea pomarea (Maupiti, Society Islands, South Pacific, mid-19th century) • Eiao monarch, Pomarea fluxa (Eiao, Marquesas, late 1970s) • :Previously considered a subspecies of the Iphis monarch (Pomarea iphis), this is an early offspring of the Marquesan stock. • Nuku Hiva monarch, Pomarea nukuhivae (Nuku Hiva, Marquesas, mid- to late 20th century) • :Previously considered a subspecies of the Marquesas monarch (Pomarea mendozae), this is another early offspring of the Marquesan stock. • Ua Pou monarch, Pomarea mira (Ua Pou, Marquesas, c. 1986) • :Also previously considered a subspecies of the Marquesas monarch, this was a distinct species most closely related to that bird and the Fatuhiva monarch (Pomarea whitneyi). • Guam flycatcher, Myiagra freycineti (Guam and Marianas, West Pacific, 1983) • :Possibly a subspecies of the oceanic flycatcher (Myiagra oceanica). OriolidaeOld World orioles and allies • North Island piopio, Turnagra tanagra (North Island, New Zealand, c. 1970?) • :Not reliably recorded since about 1900. • South Island piopio, Turnagra capensis (South Island, New Zealand, 1960s?) • :Two subspecies, T. c. minor from Stephens Island (extinct c. 1897) and the nominate subspecies T. c. capensis from the South Island mainland (last specimen taken in 1902, last unconfirmed record in 1963) Corvidaecrows, ravens, jays and magpies • Hawaiian crow, Corvus hawaiiensis (Big Island, Hawaiian Islands, 2002) • :This species is extinct in the wild, but it is being bred in captivity. CallaeidaeNew Zealand wattlebirds , male (front) and female (back) • Huia, Heteralocha acutirostris (North Island, New Zealand, early 20th century) • South Island kōkako, Callaeas cinereus (South Island, New Zealand, 1960s?) • :This species is usually considered to be extinct, as it has not been reliably recorded since 1967. However, recent reports from Fiordland suggest that it may still exist. Hirundinidaeswallows and martins • White-eyed river martin, Pseudochelidon sirintarae (Thailand, late 1980s?) • :Officially classified as critically endangered, this enigmatic species is only known from migrating birds and it was last seen in 1986 at its former roost site. Recent unconfirmed reports suggest that it may still exist in Cambodia. • Red Sea cliff swallow, Petrochelidon perdita (Red Sea area, late 20th century?) • :Known from a single specimen found in 1984; this enigmatic swallow may still exist, but the lack of recent records is puzzling. It is also alternatively placed in the genus Hirundo. Acrocephalidaeacrocephalid warblers or marsh warblers, tree warblers and reed warblers • Nightingale reed warbler, Acrocephalus luscinius (Guam, West Pacific, c. 1970s) • Pagan reed warbler, Acrocephalus yamashinae (Pagan, Marianas, West Pacific, 1970s) • :Previously considered a subspecies of the nightingale reed warbler. • Aguiguan reed warbler, Acrocephalus nijoi (Aguiguan, Marianas, West Pacific, c. 1997) • :Also previously considered a subspecies of the nightingale reed warbler. • Mangareva reed warbler, Acrocephalus astrolabii (Marianas?, West Pacific, mid-19th century?) • :Known only from two specimens found on Mangareva Island. • Garrett's reed warbler, Acrocephalus musae (Raiatea and Huahine, Society Islands, South Pacific, 19th century?) • :Two subspecies, A. m. garretti from Huahine and A. m. musae from Raiatea. Previously considered a subspecies of the Tahiti reed warbler (Acrocephalus caffer). • Moorea reed warbler, Acrocephalus longirostris (Moorea, Society Islands, South Pacific, 1980s?) • :The last reliable sighting of this bird was in 1981. A survey in 1986 / 1987 was unsuccessful in finding it. A photograph of a warbler from Moorea in 1998 or 1999 taken by Philippe Bacchet remains uncertain, as do reports from 2003 and 2010. Also previously considered a subspecies of the Tahiti reed warbler. MuscicapidaeOld World flycatchers and chats • Rück's blue flycatcher, Cyornis ruckii (Malaysia or Indochina, 20th century?) • :An enigmatic species known only from two or four possibly migrant specimens, last recorded in 1918. It may still exist in northeastern Indochina. Possibly a subspecies of the Hainan blue flycatcher (Cyornis hainanus). Megaluridaemegalurid warblers or grass warblers • Chatham fernbird, Poodytes rufescens (Chatham Islands, Southwest Pacific, c. 1900) • :Often placed in the genus Megalurus, but this is based on an incomplete review of the evidence. Cisticolidaecisticolas and allies • Tana River cisticola, Cisticola restrictus (Kenya, Africa, 1970s?) • :A mysterious species found in the Tana River Basin in small numbers at various dates but not seen since 1972. It is probably invalid; if so, it may be based on aberrant or hybrid specimens. An unconfirmed sighting was apparently reported in 2007 at the Tana River Delta. Zosteropidaewhite-eyes. Probably belong in Timaliidae. • Marianne white-eye, Zosterops semiflavus (Marianne Island, Seychelles, late 19th century) • Robust white-eye, Zosterops strenuus (Lord Howe Island, Southwest Pacific, c. 1918) • White-chested white-eye, Zosterops albogularis (Norfolk Island, Southwest Pacific, between 2006 and 2010) Pycnonotidaebulbuls • Rodrigues bulbul, Hypsipetes cowlesi (Rodrigues, Mascarenes, extinction date unknown, 17th century or 18th century might be possible) • :Known only from subfossil bones.

Its taxonomic position is thus unresolvable at present although, for biogeographic reasons and because of the surviving description, it has been suggested to have been a honeyeater. However, with the discovery of fossils of the prehistorically extinct Huahine starling (Aplonis diluvialis) on neighboring Huahine, it seems likely that this bird also belonged to this genus. • Hoopoe starling, Fregilupus varius (Réunion, Mascarenes, 1850s) • :Tentatively assigned to Sturnidae. • Rodrigues starling, Necropsar rodericanus (Rodrigues, Mascarenes, mid-18th century?) • :Tentatively assigned to Sturnidae. The bird that was variously described as Necropsar leguati or Orphanopsar leguati and was considered to be identical with N. rodericanus (which itself is known only from subfossil bones) was found to be based on a misidentified albino specimen of the grey trembler (Cinclocerthia gutturalis).

Three subspecies are known from Oahu (M. l. woahensis, extinct 1850s), Lanai (the nominate subspecies M. l. lanaiensis, extinct early 1930s) and Molokai (M. l. rutha, extinct 1980s?) and there may be a possible fourth subspecies from Maui (extinct before the late 19th century). Mimidaemockingbirds and thrashers • Cozumel thrasher, Toxostoma guttatum (Cozumel, West Indies, early in the first decade of the 21st century?) • :It is still unknown whether the tiny population rediscovered in 2004 survived Hurricanes Emily and Wilma in 2005. There have also been unconfirmed records in April 2006 and October and December 2007. IcteridaeNew World blackbirds and allies • Slender-billed grackle, Quiscalus palustris (Mexico, 1910) ParulidaeNew World warblers • Bachman's warbler, Vermivora bachmanii (southern United States, c. 1990?) • :Officially classified as critically endangered. • Semper's warbler, Leucopeza semperi (St. Lucia, West Indies, 1970s?) • :Officially classified as critically endangered.

Ploceidaeweavers • Réunion fody, Foudia delloni (Réunion, Mascarenes, c. 1672) • :Formerly Foudia bruante; the latter scientific name may actually be a color morph of the red fody (Foudia madagascariensis). Cardinalidaecardinals • Townsend's dickcissel, Spiza townsendi • Either an extinct species, a variant of the dickcissel (Spiza americana), or a hybrid. Fringillidaetrue finches and Hawaiian honeycreepers • Bonin grosbeak, Carpodacus ferreorostris (Chichi-jima, Ogasawara Islands, 1830s) • Ōū, Psittirostra psittacea (Hawaiian Islands, c. 2000?) • Kona grosbeak, Chloridops kona (Big Island, Hawaiian Islands, 1894) • Lanai hookbill, Dysmorodrepanis munroi (Lanai, Hawaiian Islands, 1918) • Kauai palila, Loxioides kikuichi (Kauai, Hawaiian Islands, early 18th century?) • Lesser koa finch, Rhodacanthus flaviceps (Big Island, Hawaiian Islands, 1891) • Greater koa finch, Rhodacanthus palmeri (Big Island, Hawaiian Islands, 1896) • Greater amakihi, Viradonia sagittirostris (Big Island, Hawaiian Islands, 1901) • Maui nukupuu, Hemignathus affinis (Maui, Hawaiian Islands, 1990s) • Kauai nukupuu, Hemignathus hanapepe (Kauai, Hawaiian Islands, late 1990s) • Oahu nukupuu, Hemignathus lucidus (Oahu, Hawaiian Islands, late 19th century) • Hawaii akialoa or lesser akialoa, Akialoa obscurus (Big Island, Hawaiian Islands, 1940) • Maui Nui akialoa, Akialoa lanaiensis (Lanai and, prehistorically, probably Maui and Molokai, Hawaiian Islands, 1892) • Oahu akialoa, Akialoa ellisiana (Oahu, Hawaiian Islands, early 20th century) • Kauai akialoa, Akialoa stejnegeri (Kauai, Hawaiian Islands, 1969) • Kākāwahie, Paroreomyza flammea (Molokai, Hawaiian Islands, 1963) • Oahu alauahio, Paroreomyza maculata (Oahu, Hawaiian Islands, early 1990s?) • :Officially classified as critically endangered. The last reliable record of this bird was in 1985, with an unconfirmed sighting in 1990. • Maui akepa, Loxops ochraceus (Maui, Hawaiian Islands, 1988) • Oahu akepa, Loxops wolstenholmei (Oahu, Hawaiian Islands, 1900s) • Ula-ai-hawane, Ciridops anna (Big Island, Hawaiian Islands, either 1892 or 1937) • Black mamo, Drepanis funerea (Molokai, Hawaiian Islands, 1907) • Hawaii mamo, Drepanis pacifica (Big Island, Hawaiian Islands, 1898) • Laysan honeycreeper, Himatione fraithii (Laysan, Hawaiian Islands, 1923) • Poouli, Melamprosops phaeosoma (Maui, Hawaiian Islands, 2004) Emberizidaebuntings and New World sparrows • Hooded seedeater, Sporophila melanops (Brazil, 20th century?) • :Officially classified as critically endangered. It is known only from a single male collected in 1823 and has variously been considered either an aberrant specimen of the yellow-bellied seedeater (Sporophila nigricollis) or a hybrid. • Bermuda towhee, Pipilo naufragus (Bermuda, West Atlantic, 17th century?) • :Known from subfossil bones and possibly from a travel report by William Strachey in 1610. ==Possibly extinct bird subspecies or status unknown==

The extinction of subspecies is a subject that is very dependent on guesswork. National and international conservation projects and research publications such as red lists usually focus on species as a whole. Reliable information on the status of vulnerable, endangered or critically endangered subspecies usually has to be assembled piecemeal from published observations, such as regional checklists. Therefore, the following listing contains a high proportion of bird taxa that may still exist, but are listed here due to any one of, or any combination of, these three factors: absence of recent records, a known threat such as habitat destruction, or an observed decline. ===Struthioniformes=== Ratites and related birds • Struthioostriches • Arabian ostrich, Struthio camelus syriacus (Arabia, 1966) • :The last record of this subspecies of the common ostrich was a bird found dead in Jordan in 1966. ===Apterygiformes=== • North Island little spotted kiwi, Apteryx owenii iredalei (North Island, New Zealand, late 19th century) • :A doubtfully distinct subspecies of the little spotted kiwi. ===Casuariiformes=== • Dromaiusemu • King Island emu, Dromaius novaehollandiae minor (King Island, Australia, 1822) • :An island dwarf subspecies of the emu; extinct in the wild c. 1805, the last captive specimen died in 1822 in the Jardin des Plantes. • Kangaroo Island emu, Dromaius novaehollandiae baudinianus (Kangaroo Island, Australia, 1827) • :Another island dwarf subspecies of the emu; extinct since c. 1827. • Tasmanian emu, Dromaius novaehollandiae diemenensis (Tasmania, Australia, mid-19th century) • :Yet another island dwarf subspecies of the emu; the last wild bird was collected in 1845, but it may have survived in captivity until 1884. It may be invalid. ===Anseriformes=== Ducks, geese and swans • Bering cackling goose, Branta hutchinsii asiatica (Commander and Kuril Islands, N Pacific, c. 1914 or 1929) • :A formerly recognised subspecies of the cackling goose (formerly called the Bering Canada goose (Branta canadensis asiatica)) which was not distinct from the similar-looking and still-existing Aleutian cackling goose (B. h. leucopareia) and is now considered to be invalid. • Rennell Island teal, Anas gibberifrons remissa (Rennell Island, Solomon Islands, c. 1959) • :A doubtfully distinct subspecies of the Sunda teal which disappeared due to predation on ducklings by introduced Mozambique tilapia (Oreochromis mossambicus). • Niceforo's yellow-billed pintail, Anas georgica niceforoi (Colombia, 1950s) • :A subspecies of the yellow-billed pintail that has not been recorded since the 1950s. • Borrero's cinnamon teal, Anas cyanoptera borreroi (Colombia, mid-20th century?) • :A subspecies of the cinnamon teal known only from a restricted area in the Cordillera Occidental of Colombia, with a couple of records from Ecuador. It was discovered in 1946 and thought to have become extinct by 1956. • Coues's gadwall, Mareca strepera couesi (Teraina, Kiribati, c. 1900) • :This island subspecies of the gadwall was discovered and named in 1874 after two birds were shot and has not been recorded since, with none found by a 1924 expedition from Honolulu's Bishop Museum. ===Galliformes=== Quails and relatives • Lake Amik black francolin, Francolinus francolinus billypayni (southern Turkey, possibly Lebanon, 1960s) • :A doubtfully distinct subspecies of the black francolin. • Sicilian black francolin, Francolinus francolinus ssp.

(Raoul, Kermadec Islands, Southwest Pacific, late 19th century?) • :Reports of the former occurrence of the species on Raoul seem to be plausible enough, but they may refer to vagrant individuals of another subspecies of the buff-banded rail. • Peruvian rail, Rallus semiplumbeus peruvianus (Peru, 20th century?) • :A subspecies of the Bogota rail which is known from a single specimen collected in the 1880s. It may still exist. • Western Lewin's rail, Lewinia pectoralis clelandi (southwestern Australia, late 1930s?) • :A subspecies of Lewin's rail not recorded since 1932 despite multiple surveys in the late 20th century. • Assumption white-throated rail, Dryolimnas cuvieri abbotti (Assumption, Astove and Cosmoledo, Aldabra, early 20th century) • :A subspecies of the white-throated rail. • Jamaican wood rail, Amaurolimnas concolor concolor (Jamaica, West Indies, late 19th century) • :The nominate subspecies of the uniform crake declined rapidly and became extinct following the introduction of the small Indian mongoose (Urva auropunctata) to Jamaica in 1872. • Intact rail, Gymnocrex plumbeiventris intactus (Melanesia, 20th century?) • :A doubtfully distinct subspecies of the bare-eyed rail known from a single specimen, c. mid-19th century, either from the Solomon Islands or New Ireland. It may still exist. • Bornean Baillon's crake, Zapornia pusilla mira (Borneo, 20th century?) • :A subspecies of Baillon's crake known from a single 1912 specimen and not found since; it may be extinct, but the species is hard to find. • Moroccan bustard, Ardeotis arabs lynesi (Morocco, late 20th century?) • :A subspecies of the Arabian bustard. Last observed in 1993 at Lac Merzouga / Lac Tamezguidat. • Luzon sarus crane, Antigone antigone luzonica (Luzon, Philippines, late 1960s) • :A subspecies of the sarus crane which is not always accepted as valid by all authorities, possibly because the existing specimens have not been thoroughly studied since it was first described. ===Pelecaniformes=== Herons and related birdspossibly paraphyletic • Ardeidaeherons, egrets, and bitterns • Bonin nankeen night heron, Nycticorax caledonicus crassirostris (Nakoudo-jima and Chichi-jima, Ogasawara Islands, c. 1890) • :A subspecies of the nankeen night heron. ===Columbiformes=== Pigeons, doves and dodos • Madeiran wood pigeon, Columba palumbus maderensis (Madeira, East Atlantic, early 20th century) • :A subspecies of the common wood pigeon. • Lord Howe pigeon, Columba vitiensis godmanae (Lord Howe Island, Southwest Pacific, 1853) • :This subspecies of the metallic pigeon was last recorded in 1853 and almost certainly became extinct by 1869. • Tongan metallic pigeon, Columba vitiensis ssp. (Vavau, Tonga, late 18th century?) • :This subspecies of the metallic pigeon is only known from a footnote in John Latham's General History of Birds and seems to have become extinct some time before 1800; possibly, however, the location is erroneous and the footnote really refers to the still-existing population on Fiji. • Réunion pink pigeon, Nesoenas mayeri duboisi (Réunion, Mascarenes, c. 1700) • :A subspecies of the pink pigeon, formerly in Streptopelia. There seems to have been at least another species of pigeon on Réunion (probably a blue pigeon species), but bones have not yet been found. It became extinct at the same time as this subspecies did. • Amirante turtle dove, Nesoenas picturatus aldabrana (Amirante Islands, Seychelles, late 20th century) • :This subspecies of the Malagasy turtle dove survived until at least 1974, after which it was hybridised out of existence through crossbreeding with the introduced nominate subspecies (N. p. picturatus). • Catanduanes bleeding-heart, Gallicolumba luzonica rubiventris (Catanduanes, Philippines, late 20th century?) • :A subspecies of the Luzon bleeding-heart known from a single specimen collected in 1971. There have been recent reports of this bird and, as much of its forest habitat still remains, it is likely that it may still exist. • Basilan bleeding-heart, Gallicolumba crinigera bartletti (Basilan, Philippines, mid-20th century?) • :A subspecies of the Mindanao bleeding-heart last reported in 1925 and, given the massive habitat destruction, is likely extinct. • Vella Lavella ground dove, Pampusana jobiensis chalconota (Vella Lavella, Makira and Guadalcanal, Solomon Islands, late 20th century?) • :A subspecies of the white-breasted ground dove or possibly a distinct species. Known from only four specimens; there are no recent records and the natives report that it has disappeared. • White-headed Polynesian ground dove, Pampusana erythroptera albicollis (Central Tuamotu Islands, 20th century?) • :This subspecies of the Polynesian ground dove, often referred to as P. e. pectoralis, became extinct at an undetermined date, but it may still exist on some unsurveyed atolls. The identity of the northern Tuamotu population, which may also possibly still exist, is undetermined to date. • Ebon crimson-crowned fruit dove, Ptilinopus porphyraceus marshallianus (Ebon?, Marshall Islands, late 19th century?) • :A subspecies of the crimson-crowned fruit dove of doubtful validity known from a single specimen collected in 1859; it is not certain whether or not this bird actually did occur on Ebon. All that can be said is that this subspecies is no longer found anywhere. • Mauke lilac-crowned fruit dove, Ptilinopus rarotongensis "byronensis" (Mauke, Cook Islands, mid- or late 19th century) • :A subspecies of the lilac-crowned fruit dove known only from the description of a now-lost specimen. The prehistorically extinct population on Mangaia likely belongs to another distinct subspecies also. • Negros spotted imperial pigeon, Ducula carola nigrorum (Negros and probably Siquijor, late 20th century?) • :A subspecies of the spotted imperial pigeon not recorded since the 1950s. • Norfolk pigeon, Hemiphaga novaeseelandiae spadicea (Norfolk Island, Southwest Pacific, early 20th century) • :A subspecies of the kererū or New Zealand pigeon not recorded since 1900. Similar birds were reported from Lord Howe Island; these seem to represent another extinct subspecies, but are undescribed to date. • Raoul Island kererū, Hemiphaga novaeseelandiae ssp. nov.

It may be a hybrid but if it is not, it is probably extinct. • Assumption Island coucal, Centropus toulou assumptionis (Assumption Island, Seychelles, early 20th century) • :A subspecies of the Malagasy coucal last recorded in 1906. It is sometimes considered synonymous with the Aldabra subspecies (C. t. insularis) which has since recolonized Assumption Island. • Cabo San Lucas groove-billed ani, Crotophaga sulcirostris pallidula (Mexico, c. 1940) • :A weakly differentiated and probably invalid subspecies of the groove-billed ani. • Bahia rufous-vented ground cuckoo, Neomorphus geoffroyi maximiliani (eastern Brazil, mid-20th century?) • :A subspecies of the rufous-vented ground cuckoo. ===Strigiformes=== True owls and barn owls Strigidaetrue owls • Sulu reddish scops owl, Otus rufescens burbidgei (Sulu, Philippines, mid-20th century) • :A subspecies of the reddish scops owl only known from a single questionable specimen. It may be invalid. • Virgin Islands owl, Gymnasio nudipes newtoni (Virgin Islands, West Indies, 20th century?) • :A subspecies of the Puerto Rican owl of somewhat doubtful validity, which occurred on several of the Virgin Islands. The last reliable records were in 1860; there were a number of unconfirmed reports during the 20th century, but it was not found in thorough surveys in 1995. • Socorro elf owl, Micrathene whitneyi graysoni (Socorro, Revillagigedo Islands, mid-20th century?) • :A subspecies of the elf owl officially classified as critically endangered. The last specimen was taken in 1932, but there was apparently still a large population in 1958; it was not found in subsequent searches and it appears to have become extinct. • Antiguan burrowing owl, Athene cunicularia amaura (Antigua, St. Kitts and Nevis, West Indies, c. 1900) • :A subspecies of the burrowing owl, last collected in 1890 and extinct by 1903. • Guadeloupe burrowing owl, Athene cunicularia guadeloupensis (Guadeloupe and Marie-Galante, West Indies, c. 1890) • :Another subspecies of the burrowing owl, extinct by 1890. • Lord Howe boobook, Ninox novaeseelandiae albaria (Lord Howe Island, Southwest Pacific, 1950s) • :A subspecies of the morepork last recorded in the 1950s. • Norfolk boobook, Ninox novaeseelandiae undulata (Norfolk Island, Southwest Pacific, 1990s) • :Individuals of the nominate subspecies of the morepork were introduced in a last-ditch effort to save the local owl population. There now exists a hybrid population of a few dozen birds; the last certainly distinct individual of N. n. undulata, a female named Miamiti, died in 1996, though individuals descended from her remain. Tytonidaebarn owls • Cave-nesting masked owl, Tyto novaehollandiae troughtoni (Nullarbor Plain, Australia, 1960s) • :Doubtfully distinct from the nominate subspecies of the Australian masked owl, but differed behaviorally. • Buru masked owl, Tyto sororcula cayelii (Buru, Indonesia, mid-20th century?) • :A subspecies of the Moluccan masked owl last recorded in 1921; the identity of a similar bird found on Seram remains to be determined. It may still exist, as an owl matching this bird's description was encountered in August 2006. • Peleng masked owl, Tyto rosenbergii pelengensis (Peleng, Banggai Islands, mid-20th century) • :A subspecies of the Sulawesi masked owl or a distinct species. It may possibly still exist, but the only known specimen was taken in 1938 and there have been no further records since then. • Samar bay owl, Phodilus badius riverae (Samar, Philippines, mid-20th century) • :A subspecies of the Oriental bay owl or a possibly distinct species. Its taxonomy is doubtful, but the only known specimen was lost in a 1945 bombing raid, so its validity cannot be verified; no population exists on Samar today. ===Apodiformes=== Swifts and hummingbirds • Miravalles indigo-capped hummingbird, Saucerottia cyanifrons alfaroana (Costa Rica, Central America, 20th century?) • :This subspecies of the indigo-capped hummingbird is only known from a specimen collected in Costa Rica in 1895. It is likely to have become extinct since then. • Alejandro Selkirk firecrown, Sephanoides fernandensis leyboldi (Alejandro Selkirk Island, Juan Fernández Islands, Southeast Pacific, 1908) • :A subspecies of the Juan Fernández firecrown last recorded in 1908. • Luzon Whitehead's swiftlet, Aerodramus whiteheadi whiteheadi (Luzon, Philippines, 20th century?) • :The nominate subspecies of Whitehead's swiftlet is only known from four specimens collected at Mount Data in 1895. Because of the lack of further records and massive habitat destruction, it is usually considered extinct. Given the size of the island, though, it may still exist. ===Coraciiformes=== Kingfishers and related birds • Sangihe dwarf kingfisher, Ceyx fallax sangirensis (Sangihe, Indonesia, 1998?) • :This subspecies of the Sulawesi dwarf kingfisher was last seen in 1997 but not during a thorough survey one year later; it is either close to extinction or already extinct. Sometimes it is said to occur on the Talaud Islands also, but this is erroneous. • Guadalcanal little kingfisher, Ceyx pusillus aolae (Guadalcanal, Solomon Islands, ?) • :A subspecies of the little kingfisher. • Rarotonga kingfisher, Todiramphus cf. tutus (Rarotonga, Cook Islands, mid-1980s?) • :There exist reports of locals that kingfishersprobably a subspecies of the chattering kingfisher (Todiramphus tutus) which is found on neighboring islands, but possibly vagrants from therewere found until around 1979 and there is a last record from 1984. Presently, no kingfishers are known to exist on Rarotonga. • "Ryukyu kingfisher", "Todiramphus cinnamominus miyakoensis" (Miyako-jima, Ryukyu Islands, late 19th century) • :Previously considered as a distinct species, then reclassified as a subspecies of the Guam kingfisher. Only seen once by scientists in 1887; the specimen taken is somewhat damaged, making identification by anything other than molecular analysis difficult. It is now thought likely that the specimen came from Guam, where the aforementioned species was distributed, rather than Miyako, which would make this subspecies invalid (it was declared invalid by the International Ornithological Congress in 2022). • Sakarha pygmy kingfisher, Corythornis madagascariensis dilutus (southwestern Madagascar, late 20th century?) • :This subspecies of the Madagascar pygmy kingfisher is only known from one specimen taken in 1974 in an area where most of its habitat had already been destroyed. However, there have been records of the species (or an uncertain subspecies) from near the type locality, suggesting it is likely that it may still exist. • Ticao hornbill, Penelopides panini ticaensis (Ticao, Philippines, 1970s) • :A subspecies of the Visayan hornbill of somewhat uncertain taxonomic status (it was possibly either a distinct species or a color morph); the last confirmed report was in 1971 and it became extinct shortly thereafter. ===Piciformes=== Woodpeckers and related birds • Grand Bahama West Indian woodpecker, Melanerpes superciliaris bahamensis (Grand Bahama, Bahamas, 1950s) • :A subspecies of the West Indian woodpecker of somewhat uncertain validity. • Javan buff-rumped woodpecker, Meiglyptes tristis tristis (Java, Indonesia, c. 1920?) • :The nominate subspecies of the buff-rumped woodpecker became rare during the 19th century due to habitat destruction. The last confirmed record was in 1880, and it is now considered to be at least very rare. • Guadalupe red-shafted flicker, Colaptes auratus rufipileus (Guadalupe Island, East Pacific, c. 1906) • :A subspecies of the northern flicker (formerly considered to be a subspecies of the red-shafted flicker, as C. cafer rufipileus), it was last recorded in 1906 and not found again in both 1911 and 1922. It may be invalid. Recently, vagrant birds of a mainland red-shafted northern flicker subspecies (which one is unknown) have begun recolonizing the island as the habitat improved after the extirpation of feral goats. • Northern white-mantled barbet, Capito hypoleucus hypoleucus (Colombia, extant) • :The nominate subspecies of the white-mantled barbet has been considered extinct, but has been recorded recently. • Botero white-mantled barbet, Capito hypoleucus carrikeri (Colombia, extant) • :Another subspecies of the white-mantled barbet, also considered extinct by some sources, but confirmed extant by researchers in Colombia. • Todd's jacamar, Brachygalba lugubris phaeonota (Brazil, late 20th century?) • :A subspecies of the brown jacamar, or possibly a hybrid, a color morph or a distinct species. It may still exist, as it is only known from a remote and seldom-visited area. • Cebu white-bellied woodpecker, Dryocopus javensis cebuensis (Cebu, Philippines, 20th century) • :A subspecies of the white-bellied woodpecker only known by three specimens collected before 1900. ===Accipitriformes=== Birds of prey • Cape Verde kite, Milvus (milvus) fasciicauda (Cape Verde Islands, East Atlantic, 2000) • :Considered either a subspecies of the red kite, a distinct species, or a hybrid between the red and black kite (Milvus migrans), the validity of this taxon has recently been questioned on the basis of molecular analysis; however, hybridization and a confusing molecular phylogeny of red kite populations, coupled with the distinct phenotype of the Cape Verde birds, suggest that the taxonomic status of this form is far from resolved. • Car Nicobar sparrowhawk, Accipiter butleri butleri (Car Nicobar, Nicobar Islands, 20th century?) • : The nominate subspecies of the Nicobar sparrowhawka species which is itself currently classified as vulnerableis possibly extinct. It was last reliably recorded in 1901 and, despite searches, has not been sighted after an unconfirmed record in 1977; however, the species is known for being very shy and a population may persist unrecorded. ===Falconiformes=== Falcons • Volcano Islands peregrine falcon, Falco peregrinus furuitii (Ogasawara Islands, 1940s) • :A subspecies of the peregrine falcon from the Ogasawara Islands. No sightings have been reported since 1945. A survey in 1982 failed to record it. Only known from Iwo Jima and Torishima. ===Psittaciformes=== Parrots • Sangir red-and-blue lory, Eos histrio histrio (Sangir Archipelago, Indonesia, 1990s?) • :The nominate subspecies of the red-and-blue lory was hybridised out of existence through crossbreeding with escaped captive individuals of its other still-existing subspecies, Challenger's red-and-blue lory (E. h. challengeri), with the last certainly distinct individuals disappearing in the 1990s or even much earlier than that. • Réunion parakeet, Psittacula eques eques (Réunion, Mascarenes, mid-18th century) • :Known only from a painting and descriptions; the nominate subspecies of the echo parakeet, with the other one being the still-existing Mauritius parakeet (P. e. echo). • Siquijor hanging parrot, Loriculus philippensis siquijorensis (Siquijor, Philippines, 20th century?) • :A subspecies of the Philippine hanging parrot or colasisi; it is either very rare or already extinct. • Sinú brown-throated parakeet, Eupsittula pertinax griseipecta (Colombia, mid- or late 20th century?) • :A subspecies of the brown-throated parakeet known from only two specimens collected in 1949 which are of unclear taxonomic and conservation status. • Culebra Island amazon, Amazona vittata gracilipes (Culebra Island, West Indies, early 20th century) • :A weakly differentiated subspecies of the Puerto Rican amazon, which is itself highly endangered. ===Passeriformes=== Perching birds Pittidaepittas • Bougainville black-faced pitta, Pitta anerythra pallida (Bougainville, Solomon Islands, mid-20th century?) • :A subspecies of the black-faced pitta. Once common on Bougainville; not recorded since 1938, but it is likely to have been overlooked. • Choiseul black-faced pitta, Pitta anerythra nigrifrons (Choiseul, Solomon Islands, late 20th century?) • :Another subspecies of the black-faced pitta. Not found during recent searches; doubtful records from nearby islands, but it is also likely to have been overlooked.

It has not been recorded since the 1950s. Furnariidaeovenbirds • Peruvian scale-throated earthcreeper, Upucerthia dumetaria peruana (Peru, 20th century?) • :A subspecies of the scale-throated earthcreeper; it is known only from two specimens taken in the early 1950s at Puno, Peru and has not been seen or found since. It may still exist, as there is no obvious reason why it should have become extinct. • Northern stripe-crowned spinetail, Cranioleuca pyrrhophia rufipennis (northern Bolivia, 20th century?) • :A subspecies of the stripe-crowned spinetail known only from a few specimens and not recorded since the 1950s; it may be endangered or possibly extinct. Formicariidaeantpittas and antthrushes • Northern giant antpitta, Grallaria gigantea lehmanni (Colombia, 20th century?) • :A subspecies of the giant antpitta (or possibly of the great antpitta, in which case it would be G. excelsa lehmanni) apparently not recorded since the 1940s. It may still exist in Puracé National Natural Park, where there is plentiful habitat remaining. • Antioquia brown-banded antpitta, Grallaria milleri gilesi (Antioquia, Colombia, 20th century?) • :A subspecies of the brown-banded antpitta recently described from a specimen collected in 1878. It has not been recorded since, despite surveys at a number of likely locations. MaluridaeAustralasian "wrens" • MacDonnell Ranges thick-billed grasswren, Amytornis modestus modestus (Northern Territory, Australia, 1936) • :The nominate subspecies of the thick-billed grasswren.

The latest record comes from 2002, suggesting a population is likely to still exist, but it is very rare. PetroicidaeAustralasian "robins" • Tiwi Island hooded robin, Melanodryas cucullata melvillensis (Tiwi Islands, Australia, 1992) • :A subspecies of the hooded robin last observed in 1992 and not found in exhaustive searches later in the 1990s. Cinclosomatidaewhipbirds and allies • Mount Lofty spotted quail-thrush, Cinclosoma punctatum anachoreta (Australia, mid-1980s?) • :A subspecies of the spotted quail-thrush last recorded in 1983 and not found in a survey the following year. Artamidaewoodswallows, currawongs and allies • Western pied currawong, Strepera graculina ashbyi (Victoria, Australia, 1927) • :This subspecies of the pied currawong has been hybridised out of existence by crossbreeding with other subspecies, which probably came into contact with it following habitat destruction in the 1830s. The last certainly distinct individuals were recorded in 1927. Monarchidaemonarch flycatchers • Negros celestial monarch, Hypothymis coelestis rabori (Negros and possibly Sibuyan, Philippines, late 20th century?) • :A subspecies of the celestial monarch; not uncommon on Negros in 1959, but not recorded since then.

(Marshall Islands, Micronesia, c. 1880?) • :Oral tradition and some early reports mention a bird called the annañ which inhabited some of the Marshall Islands. The best match is the Nauru reed warbler; the annañ might have been an undescribed subspecies of that species or a distinct but related species of reed warbler. the last unquestionable record dates from 1897 and a thorough search in 1901 failed to record it. • San Clemente Bewick's wren, Thryomanes bewickii leucophrys (San Clemente Island, East Pacific, 1941) • :Another subspecies of Bewick's wren last recorded in 1941. • Daito wren, Troglodytes troglodytes orii (Daito Islands, Northwest Pacific, c. 1940) • :A disputed subspecies of the Eurasian wren; it is known from a single specimen that may have been a vagrant individual and, therefore, it is possibly invalid. • Guadeloupe house wren, Troglodytes aedon guadeloupensis (Guadeloupe, West Indies, late 20th century?) • :Found in 1914, 1969 and the 1970s; now very rare or already extinct.

It could have been wiped out by introduced feral cats, but the island is poorly known and so it should not be presumed extinct yet. • Isle of Pines solitaire, Myadestes elisabeth retrusus (Isla de la Juventud, West Indies, 20th century) • :A subspecies of the Cuban solitaire. The last confirmed records were in the 1930s, with unconfirmed reports in the early 1970s.
