Endangered
Black Rosy Finch
Leucosticte atrata
Black Rosy Finch is a perching bird in the family Fringillidae (order Passeriformes) — Leucosticte atrata, recorded as Endangered.
Appearance
There is a patch of grey at the back of the head. The grey-crowned rosy finch has a brown body instead of black and the brown-capped rosy finch and lacks the grey patch on the back of the head.
Published measurements include mass about 25.
Range and habitat
The black rosy finch's breeding habitat is mountain areas above the tree-line, amongst alpine rocks and cliffs. Its distribution range is between that of the grey-crowned rosy finch (L. Tephrocotis), that is located to north and west, and the brown-capped rosy finch (L. Australis), that is located to the south and east. The black rosy finch or black rosy-finch is a passerine bird in the family Fringillidae native to alpine areas above treeline, of the western United States.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Breeding
The black rosy finch builds a cup nest in a cavity on a cliff. Most birds migrate short distances to lower elevations and further south and return to the alpine areas in April.
A male will defend its female's territory during breeding season, not just the nest but wherever she goes. When breeding both males and females develop throat pouches, known as gular pouches or gular skin, to carry food to their chicks, a trait seen in only one other North American genus, Pinicola.
