The Chilean woodstar (''Eulidia yarrellii'') is a small bird in the hummingbird family, Trochilidae. It is restricted to northernmost Chile with reports from southern Peru. Its natural habitats are dry shrubland and rural gardens. It is threatened by habitat loss and is classed as a Critically endangered species. It is usually classified in its own genus ''Eulidia'' but is sometimes placed with the purple-collared woodstar in the genus ''Myrtis''. In 2013 it was classed as Endangered but recently, it was classed as Critically Endangered by the IUCN Red List. ==Description== It is the smallest bird in Chile,〔Aves de Chile (1999-2008) (Chilean Woodstar. ) Retrieved 2 July 2008.〕 7.2 to 7.5 centimetres long with the bill accounting for 1.5 centimetres of this.〔Schulenberg, Thomas S.; Stotz, Douglas F.; Lane, Daniel F.; O'Neill John P. & Parker, Theodore A. III (2007) ''Field Guide to the Birds of Peru'', Christopher Helm, London. ISBN 978-0-7136-8673-9〕 The bill is black, straight, slender and fairly short, about the same length as the head. The tail is often held in a cocked position. The adult male is iridescent green above and whitish below with green sides. The throat is reddish-purple and blue but often appears blackish. The tail is long, black and forked with long, pointed outer-feathers that curve inwards. Females are green above and have a white throat while the rest of the underparts are mostly very pale buff, darkest on the belly and thighs. The tail is short and slightly graduated with green inner feathers. The outer feathers are black with a rufous base and white tip. Immature males are similar to the female but have a mottled throat and may have elongated outer tail-feathers.〔Jaramillo, Alvaro; Burke, Peter & Beadle, David (2003) ''Field Guide to the Birds of Chile'', Christopher Helm, London. ISBN 0-7136-4688-8〕 The Peruvian sheartail is similar but the male has two elongated white feathers in its tail while the female tends to have a whiter belly and more buff throat than the woodstar. The tail is rarely cocked but is frequently pumped vigorously up and down unlike the woodstar.〔 The call is a series of rasping notes, quieter and less musical than the call of the Peruvian sheartail.〔 The male has a high-pitched, buzzing display call.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chilean woodstar」の詳細全文を読む スポンサード リンク
