Habitat:
The black rosy finch is found in high-altitude grasslands and alpine rocks, also using desert areas during the winter. They are found at altitudes of 3.000-4.500 m.

Breeding:
Black rosy finches breed in June-August. The nest is a bulky cup made of grasses, moss, and sometimes feathers mixed with grass and animal hair. It is placed in a crevice or hole in a cliff, usually in an inaccessible place, or sometimes in a niche among boulders of a rock slide. There the female lays 3-6 white eggs, which she incubates alone for 12-14 days. The chicks are fed by both parents and fledge about 20 days after hatching, only becoming fully independent 2 weeks later. Each pair raises a single brood per year.

Conservation:
IUCN status – LC (Least Concern)
This species has a large breeding range and a global population estimated at 20.000 individuals. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
