The turquoise-throated hummingbird ( Eriocnemis godini ), also known as turquoise snow pants , is a presumably extinct hummingbird from the genus of woolen pants .
description
This species reached a length of 10 to 11 centimeters. The plumage of the males was predominantly green in color with a purple-blue throat. Both sexes had purple-blue under tail-coverts and a straight black beak. The top and most of the bottom shimmered gold-green in the males. The rear part and the upper tail-coverts were colored bluish green. The throat was a pale purplish blue tint and the forked tail was bluish black. In the females, the throat markings were missing, the plumage was less bright and the belly had a more intense gold color. As with all woolen pants, the legs were covered with fluffed tufts of white feathers.
distribution
The turquoise-throated hummingbird was widespread in Ecuador on the Guayllabamba south of Perucho in the Pichincha Province in the north of the country. Two other specimens are believed to come from Pasto in the southern Nariño Province in Colombia .
status
The IUCN classifies the species in the category of "threatened with extinction" ( critically endangered ) with the addition "possibly extinct" ( possibly extinct ) a. Only six specimens of this hummingbird are known, which were found in the 19th century. Four are from Ecuador and two bellows were in the Colombian Bogotá acquired. The bushland in its original homeland in the Guayllabamba Valley has been completely destroyed. After an unconfirmed sighting in 1976, an intensive search was carried out in 1980, but it did not bring any result.
Etymology and history of research
The type specimen of the turquoise-throated hummingbird came from the gorges of the Guayllabamba valley and was brought back by Bourcier on his return from Ecuador. Jules Bourcier described the species under the name Trochilus Godini . It was later assigned to the genus Eriocnemis . This name is derived from the Greek words »erion ἔριον « for »wool« and »knēmis κνημίς « for »cuff, leg splint «. Since the author described Trochilus Bougueri and Trochilus Condamini in the same article, the specific epithet is most likely dedicated to Louis Godin (1704–1760), who worked with Pierre Bouguer (1698–1758) and Charles Marie de La Condamine (1701–1774) between 1735 and was on an expedition to the viceroyalty of Peru in 1744 .
