Black Rosy Finch

The black rosy finch, or Leucosticte atrata, presents a striking plumage with a predominantly black head, back, and breast. A delightful contrast is seen in the pink hues adorning the belly, rump, and wings. A distinctive grey patch graces the back of the head, while the bird's legs are short and black, complementing a long, forked tail.

Identification Tips

When identifying the black rosy finch, look for the black plumage on the upper parts and the pink on the underparts. The grey patch at the back of the head is a key distinguishing feature. The bird's short black legs and forked tail are also characteristic.

Habitat

This species is native to the alpine areas above the treeline, where it frequents rocky terrains and cliffs. Such habitats contribute to its status as one of North America's least studied birds due to the challenging accessibility.

Distribution

The black rosy finch is the most range-restricted member of its genus, found in the western United States. Its range lies between that of the grey-crowned rosy finch to the north and west, and the brown-capped rosy finch to the south and east.

Behaviour

These birds exhibit a partial migratory pattern, moving to lower elevations and further south during the colder months, returning to alpine areas in April. They forage on the ground and may also catch insects in flight. The black rosy finch is known to feed in small flocks, occasionally mixing with grey-crowned rosy finches. During the breeding season, males defend their mate's territory vigorously. Both sexes develop gular pouches to transport food to their chicks, a trait shared with only one other North American genus.

Song & Calls

The call of the black rosy finch is a distinctive buzz-sounding "chew," which can be heard across the alpine landscapes they inhabit.

Breeding

The black rosy finch constructs a cup-shaped nest within cavities on cliffs, often in protected areas such as mine shafts or caves. The nests are crafted from grass and stems and lined with fine grass, hair, and feathers.

Similar Species

The grey-crowned rosy finch can be differentiated by its brown body and lack of a grey patch on the back of the head. The brown-capped rosy finch also lacks this grey patch and has a different body coloration.

Diet and Feeding

The diet consists mainly of seeds from weeds and grasses, as well as insects. These birds often feed in areas where snow is melting, uncovering food items and where new plant shoots are growing.

Conservation Status

The black rosy finch is currently listed as Endangered on the IUCN Red List. Its specialized habitat and limited range make it a species of conservation concern.
