The long-legged bunting (Emberiza alcoveri) is an extinct flightless species of bunting. It was distinguishable by its long legs and short wings, and it inhabited Tenerife, one of the Canary Islands. It is one of the few flightless passerines known to science, all of which are now extinct.

Taxonomy

The yellowhammer (Emberiza citrinella), a close relative of the long-legged bunting

This bunting belongs to the genus

Emberiza, and is most closely related to Cabanis's bunting (E. cabanisi) and the yellowhammer (E. citrinella).[1] Emberiza is a genus inside the bunting family, Emberizidae, which is made up of small, seed-eating birds with distinctive bill shapes.[2] The species name, alcoveri, is in honour of J. A. Alcover, who contributed to fossil fauna knowledge and information.[1]

Description

The

omnivorous, like the other species in its genus. It likely ate seeds and invertebrates. However, because of its differently-shaped bill, harder seeds could have been included in its diet.[1]

Distribution and habitat

The long-legged bunting was a native of the Canary Islands. Bones from this species have only been found in the volcanic cave Cueva del Viento, on the island of Tenerife. Other species that lived alongside this bunting include various birds, mammals, and lizards. This species likely lived in the laurel forest or the transition forest, as food would be plentiful and the herb layer would protect against aerial predators.[1]

Extinction

The long-legged bunting had lived in Tenerife during the

Upper Pleistocene and the Holocene. Humans arrived over 2,000 years ago, bringing with them invasive species such as goats, pigs, cats, and sheep that may have preyed on the birds or modified their habitat. The Europeans affected Tenerife even more when they arrived in the 1400s, introducing rats and clearing forest for agriculture. The long-legged bunting seems to have been driven to extinction because of these invasive species and the destruction of its habitat.[1]
