Cuban macaw

Early explorers of Cuba, such as Christopher Columbus and Diego Álvarez Chanca, mentioned macaws there in 15th- and 16th-century writings. Cuban macaws were described and illustrated in several early accounts about the island. Bechstein's description was based on the bird's entry in the French naturalist François Le Vaillant's 1801 book Histoire Naturelle des Perroquets, wherein it was referred to as ''l'Ara Tricolor''. Le Vaillant's account was itself partially based on the late 18th century work Planches Enuminées by the French naturalists Comte de Buffon and Edme-Louis Daubenton, as well as a specimen in Paris; as it is unknown which specimen this was, the species has no holotype. The French illustrator Jacques Barraband's original watercolour painting, which was the basis of the plate in Le Vaillant's book, differs from the final illustration in showing bright red lesser wing covert feathers ("shoulder" area), but the significance of this is unclear. in Museum für Naturkunde, Berlin, one of 19 specimens in existence Today, 19 skins of the Cuban macaw exist in 15 collections worldwide (two each in Natural History Museum at Tring, Muséum national d'histoire naturelle in Paris, the Swedish Museum of Natural History, and the Smithsonian Museum), but many are of unclear provenance. Several were provided by the Cuban naturalist Juan Gundlach, who collected some of the last individuals that regularly fed near the Zapata Swamp in 1849–50. Some of the preserved specimens are known to have lived in captivity in zoos (such as Jardin des Plantes de Paris, Berlin Zoo, and Amsterdam Zoo) or as cagebirds. The single specimen at World Museum, National Museums Liverpool died in Edward Smith-Stanley, 13th Earl of Derby's aviaries at Knowsley Hall in 1846. Several more skins are known to have existed, but have been lost. Four subfossil specimens have been discovered: half a carpometacarpus (a hand bone) from a possibly Pleistocene spring deposit in Ciego Montero, identified by extrapolating from the size of Cuban macaw skins and bones of extant macaws (reported in 1928), a rostrum from a Quaternary cave deposit in Caimito (reported in 1984), a worn skull from Sagua La Grande, which was deposited in a waterfilled sinkhole possibly during the Quaternary and associated with various extinct birds and ground sloths (reported in 2008), and a fragmentary carpometacarpus from Upper Pleistocene layers of the El Abrón Cave in Pinar del Río, the first physical evidence from the western part of Cuba (reported in 2024). In 2021, the first archaeological remains were reported, a tarsometatarsus (a lower leg bone) and upper beak from two sites in Old Havana dated to the 17th and 18th centuries. Related Caribbean macaws As many as 13 now-extinct species of macaw have variously been suggested to have lived on the Caribbean islands, but many of these were based on old descriptions or drawings and only represent hypothetical species. Only three endemic Caribbean macaw species are known from physical remains: the Cuban macaw, the Saint Croix macaw (A. autochthones), which is known only from subfossils, and the Lesser Antillean macaw (A. guadeloupensis), which is known from subfossils and reports. Macaws are known to have been transported between the Caribbean islands and from mainland South America to the Caribbean both in historic times by Europeans and natives, and in prehistoric times by Palaeoamericans. Historical records of macaws on these islands, therefore, may not have represented distinct, endemic species; it is also possible that they were escaped or feral foreign macaws that had been transported to the islands. All the endemic Caribbean macaws were likely driven to extinction by humans in historic and prehistoric times. The identity of these macaws is likely to be further resolved only through fossil finds and examination of contemporary reports and artwork. A stylised 1765 painting of a macaw by the British Lieutenant L. J. Robins, published in a volume called The Natural History of Jamaica, matches the Cuban macaw, and may show a specimen that had been imported there; however, it has also been claimed that the painting shows Gosse's macaw. In 2017, the Australian ornithologist Joseph M. Forshaw found the Cuban, the Lesser Antillean, and the supposed Gosse's macaw so similar that they could have been the same species transported between islands, or, with macaws that possibly occurred on other islands, been closely related and possibly derived from the scarlet macaw (A. macao). Rothschild's 1907 book Extinct Birds included a depiction of a specimen in the Liverpool Museum which was presented as a Cuban macaw. In a 1908 review of the book published in The Auk, the American ornithologist Charles Wallace Richmond claimed that the picture looked sufficiently dissimilar from known Cuban macaws that the specimen may actually be of one of the largely unknown species of macaw, such as a species from Haiti. This suggestion has not been accepted. The idea that the name Ara tricolor applied to a Hispaniolan species had gained acceptance by 1989, but in 1995, the British ornithologist Michael Walters pointed out that birds had indeed been described from Cuba prior to 1822, that the supposed differences in colouration were of no importance, and that the basis of Wetherbee's argument was therefore invalid. There is no clear evidence for a species of macaw on Hispaniola, and later researchers concurred with Walters. }} The Cuban macaw was smaller than the related extant species, and one of the smallest Ara species, which suggests smaller size may have been the ancestral state of the group, though it may also have become smaller after becoming established in the Antilles. Johansson and colleagues estimated that the Cuban macaw had diverged from its mainland relatives around 4 million years ago, during the early Pliocene. Since this is after the land bridge that is thought to have connected the Greater Antilles with South America ceased to exist, the ancestors of the Cuban macaw must have dispersed to the Antilles over open water. Therefore, the Cuban macaw was not a recent offshoot of the scarlet macaw, having a long independent history on Cuba. Johansson and colleagues therefore noted that though many of the extinct species of Caribbean macaws that had been described in the past are probably dubious, there would have been ample time for a radiation of macaws there, based on how long the Cuban species had been separated from the mainland species. == Description ==

, Leiden The Cuban macaw had a red forehead fading to orange and then to yellow at the nape of the neck. It had white unfeathered areas around the eyes, and yellow irises. The face, chin, chest, abdomen and thighs were orange. The upper back was brownish red with feathers scalloped with green. The rump, undertail feathers, and lower back were blue. The wing feathers were brown, red and purplish blue. The upper surface of the tail was dark red fading to blue at the tip, and the under surface of the tail was brownish red. The sexes were identical in external appearance, as with other macaws. The Cuban macaw was physically distinct from the scarlet macaw in its lack of a yellow shoulder patch, its all-black beak, and its smaller size. The American zoologist Austin Hobart Clark reported that juvenile Cuban macaws were green, though he did not provide any source for this claim. It is unclear whether green birds spotted on the island were in fact juvenile Cuban macaws or if they were instead feral military macaws. == Behaviour and ecology ==

Little is known about the behaviour of the Cuban macaw and its extinct Caribbean relatives. Gundlach reported that it vocalised loudly like its Central American relatives and that it lived in pairs or families. Its speech imitation abilities were reportedly inferior to those of other parrots. Nothing is known about its breeding habits or its eggs, but one reported nest was a hollow in a palm. It is thought to have been unique to this species, and is therefore an example of coextinction. The feather mite species Genoprotolichus eurycnemis and Distigmesikya extincta have also been reported from Cuban macaw skins, the latter new to science. == Distribution and habitat ==

, 2009; the Cuban macaw lived in the area The range of the Cuban macaw's distribution at the time of European settlement on the main island of Cuba is unclear, but the species was reportedly becoming rare by the mid-19th century. It may have been restricted to the central and western part of Cuba. Most accounts from the 19th century are based on Gundlach's reports from the immense Zapata Swamp, where the species was somewhat common near the northern edge. By the 1870s, it was becoming rarer and had retreated to the interior. Early writers also claimed it lived on Haiti and Jamaica, but this is no longer accepted. The habitat of the Cuban macaw was open savanna terrain with scattered trees, typical of the Zapata Swamp area. Cuba was originally widely covered in forest, much of which has since been converted to cropland and pastures. Lomas de Rompe, where the macaw was also reported, had rainforest-like gallery forest. == Extinction ==

Hunting has been proposed as a factor in the extinction of the Cuban macaw. Parrots were hunted, kept as pets, and traded by Native Americans in the Caribbean before the arrival of Europeans. The Cuban macaw was reportedly "stupid" and slow to escape, and therefore was easily caught. It was killed for food; the Italian traveler Gemelli Careri found the meat tasty, but Gundlach considered it tough. According to the British writer Errol Fuller, aviculturalists are rumoured to have bred birds similar in appearance to the Cuban macaw. These birds, however, are reportedly larger in size than the Cuban macaw, having been bred from larger macaw species. == References ==
