Cool Facts

  • The Gray-crowned Rosy-Finch is divided into six subspecies. The Pribilof and Aleutian forms are particularly large, weighing approximately twice as much as the smaller forms. The three subspecies found in the interior mountains have brown cheeks and the others have gray cheeks.
  • Perhaps because of its remote breeding sites, which allow little contact with humans, the Gray-crowned Rosy-Finch seems almost fearless. On its breeding grounds, foraging birds can be approached to within 1-2 meters (3-6 feet).
  • Although all forms of rosy-finches in North American were merged with the Asian Rosy-Finch (Leucosticte arctoa) into a single species from 1983 to 1993, justification for this action was viewed as insufficient and was contradicted by genetic, biochemical, and morphological evidence. Once again, three distinct North American species of rosy-finch are recognized, with Gray-crowned Rosy-Finch being the most widely distributed and abundant form.
  • Because of the remoteness of its breeding sites, few nests of the Gray-crowned Rosy-Finch have been found.

Habitat


Mountains

Breeds in alpine areas, usually near snow fields or glaciers, talus, rockpiles, and cliffs. Winters in open country, including mountain meadows, shrublands, roadsides, towns, cultivated areas, rocky hillsides, and margins of dry ditches.

Food

Behavior


Ground Forager

Generally forages among low plants and picks insects from plants and off of snowfields. Also captures flying insects on the wing and forages in conifers.

Conservation

status via IUCN

Least Concern

Little information. Remoteness of breeding sites reduces impacts of human activity.
