The black-bellied hummingbird ( Eriocnemis nigrivestis ) or sometimes black-breasted snow pants is a species of bird from the hummingbird family (Trochilidae). The species is endemic to Ecuador . The IUCN classifies the population as " Critically Endangered " .

features

The black-bellied hummingbird with panties reaches a body length of about 9 cm, with the short, straight black beak 1.5 cm and the slightly forked dark steel-blue tail 3.5 cm long. The males have a blackish underside with a purple-blue throat and under tail-coverts. There are white puffs on the feet. The upper side of the females shimmers bronze-green, which turns into a bluish green color at the rump and upper tail-coverts. The underside is golden green with a pale blue on the chin. The under tail-coverts and tufts of legs are like those of the male.

behavior

For food intake they prefer to look for the species Palicourea amethystina , which belongs to the red family , but the flowers of bushes, herbs and vines are also among their sources of food. In a study of the ecology of the species, they flew to the heather family Macleania macrantha , Thibaudia floribunda , Disterigma acuminatum , the myrtle- like species Miconia hymenanthera , the fuchsia species Fuchsia sylvatica, and species of the Rubus genus . The vines that were flown to included the species Heppiella ampla , which belongs to the Gesneria family , the species Manettia recurva , which belongs to the red family , the genus Burmeistera , which belongs to the bluebell family, and the species Tropaeolum pubescens, which belongs to the nasturtium . They have also been observed on Miconia corymbiformis and on the shrub species Psychotria uliginosa . Usually they get their nectar directly from the entrance of the flowers. The flowers are about as long as the beak of the black-bellied hummingbird. Occasionally they drill into the flowers or use holes that the steel hookbill ( Diglossa lafresnayii ) has already made.

Vocalizations

Her singing sounds like a monotonous metallic Tsit, Tsit, Tsit ... on.

distribution and habitat

Distribution area (green) of the black-bellied hummingbird

You move on grassy slopes with crippled mountain forests with blueberry bushes and heather. The males move to higher altitudes outside of the breeding season. The species occurs at altitudes between 2440 and 3700 meters. They are only very limited on the Pichincha and Atacazo and possibly on the Imbabura . There are few reports of occurrence in the mountainous areas adjacent to the volcanoes.

Etymology and history of research

Jules Bourcier and Étienne Mulsant described the black-bellied panty hummingbird under the name Trochilus nigrivestis . The type specimen came from Tumbaco . In 1849 Heinrich Gottlieb Ludwig Reichenbach introduced the new genus Eriocnemis , which was only later assigned to the black-bellied hummingbird. This name is derived from the Greek words »erion ἔριον « for »wool« and »knēmis κνημίς « for »cuff, leg splint «. The species name is composed of the Latin words "niger" for "black" and "vestis" for "garment".
