The
Black Rosy-Finch is a rather uncommon bird that breeds in high elevation
areas of the northern Rocky Mountains in the western United States.
They summer in rocky tundra areas above treeline, often in areas near
permanent snow and ice. They are most often encountered by people
during the winter months, as they move to lower elevations for the winter,
and can sometimes be found at feeders in suburban areas. They may
hybridize with Brown-capped
Rosy-Finch and the
Gray-crowned Rosy-Finch where their ranges overlap. All three
species are closely related.
Habitat: Found in barren tundra areas on high
elevation areas of the Rocky Mountains, usually in rocky areas with
permanent snowfall nearby. During the winter, they will move to lower
elevation valleys and plateaus, using a variety of open habitats.
Diet: Feeds heavily on seeds, especially during
the winter months when seeds may make up nearly all of its diet.
During the summer months, they also will feed on insects, particularly
during the breeding season when young are being raised. They will also
sometimes eat other items such as new shoots and buds of plants.
Behavior: Does most of its foraging by walking
along the ground in search of seeds. They will also sometimes feed in
low vegetation, or fly up from the ground to capture insects in flight.
Nesting: The nest of a Black Rosy-Finch is a cup
of grasses and moss, built in a crevice on a cliff face or in a crevice
between large rocks. The female usually lays 4 or 5 eggs, and she
alone incubates them. After the eggs hatch, both parents help to feed
the young. The young leave the nest after about 3 weeks.
Song: The song of a Black Rosy-Finch is a slow
series of whistling notes that descend throughout the song.
Migration: Most birds move to lower elevations in
the fall, with some found in winter well south of their breeding range.
Feeders: Will attend feeders for various
seeds.
