Lilford's wall lizard

P. lilfordi is named in honour of Thomas Powys, 4th Baron Lilford, a British ornithologist who studied the fauna of the Balearics. ==Description==

Lilford's wall lizard grows to a maximum snout-to-vent length (SVL) of , but adults are usually a little smaller than this. The tail is about 1.8 times as long as the body. It is a robust streamlined lizard with a short head and rounded body with smooth, unkeeled scales. The dorsal surface is usually greenish or brownish but varies much between different island subpopulations. There is usually a pale dorso-lateral stripe and there may be several dark streaks or three dark lines running along the spine. The flanks may be slightly reticulated and the underside is white, cream or pinkish. The throat may be blotched with darker colour. Juveniles sometimes have a blue tail. ==Geographic range==

Lilford's wall lizard is native to the Gymnesian Islands, including Mallorca, Menorca, the Cabrera Archipelago to the south of Mallorca, and the neighbouring rocky islets, which united into a single landmass during the colder periods of the Pleistocene. In historical times it has been extirpated from the two large islands and is now only present on the islets. It was never found on the Pityusic Islands, west of the Gymnesian Islands. ==Habitat==

P. lilfordi is found at low altitudes. It is a mainly ground-dwelling species and largely inhabits rocky areas and scrubland, although it is found in woodland on Cabrera. ==Behaviour==

Lilford's wall lizard is a relatively tame lizard and easy to approach. It mainly feeds on insects, spiders and other arthropods, snails and some vegetable matter. This includes flowers and fruits, nectar and pollen. Some plants endemic to the Gymnesian Islands depend on this lizard for pollination. It is opportunistic around birds' nests in the use of scraps of food that have been regurgitated by gulls for their chicks. It also sometimes moves to the vicinity of nests of the Eleonora's falcon (Falco eleonorae) and feeds on the remains of its prey and the flies that accumulate around the nesting site. It is sometimes cannibalistic, eating juveniles and the tails of other lizards of its own species. ==Reproduction==

P. lilfordi is oviparous. ==Conservation status==

The population of this lizard seems to be in decline. It was at one time very numerous on Menorca and Mallorca but is no longer found on either. This extirpation may have been caused by the proliferation of cats and by other introduced predators, possibly the false smooth snake (Macroprotodon cucullatus) and the weasel (Mustela nivalis). Its total area of occupancy on all the small islands on which it is now present is less than ; so the IUCN lists it as being "Endangered". ==Subspecies==

There are 27 recognized subspecies many of which are found on only a single island: • Podarcis lilfordi lilfordi – Aire islet, off the southeastern coast of Menorca • Podarcis lilfordi addayae • Podarcis lilfordi balearica • Podarcis lilfordi brauni – Colom islet, off Menorca • Podarcis lilfordi carbonerae – Carbonera islet, off Menorca • Podarcis lilfordi codrellensis – Binicondrell islet, off the southern coast of Menorca • Podarcis lilfordi colomi – Colomer islet, off northeast Menorca • Podarcis lilfordi conejerae • Podarcis lilfordi espongicola • Podarcis lilfordi estelicola • Podarcis lilfordi fahrae • Podarcis lilfordi fenni – Sanitja islet, off northern Menorca • Podarcis lilfordi gigliolii – Dragonera islet, off east of Majorca • Podarcis lilfordi hartmanni • Podarcis lilfordi hospitalis • Podarcis lilfordi imperialensis • Podarcis lilfordi isletasi • Podarcis lilfordi jordansi • Podarcis lilfordi kuligae • Podarcis lilfordi nigerrima • Podarcis lilfordi planae • Podarcis lilfordi probae • Podarcis lilfordi porrosicola – Porros islet, north of Menorca • Podarcis lilfordi rodriquezi – Ratas Island lizard – Formerly Ratas Island, in Mahón's harbour (Menorca). Extinct after island was demolished in harbour expansion. • Podarcis lilfordi sargantanae – islets located by the north coast of Majorca (Sargantana, Ravells, Bledes and Tusqueta). • Podarcis lilfordi toronis • Podarcis lilfordi xapaticola Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in genus other than Podarcis. ==References== ==Further reading==
