- 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.
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.
Seeds, insects, and some vegetation.
- Clutch Size
- 2–6 eggs
- Egg Description
- White and unmarked, or with some reddish or brownish specks.
- Condition at Hatching
- Helpless and covered with long, fluffy gray down that only partially conceals skin.
Bulky cup of moss, lichen, grass, and sedge, lined with fine grass, hair, wool, and feathers. Placed in crack or hole in cliff or on small cliff ledge under overhanging rocks, occasionally on the ground, and rarely on a building. Usually not visible, totally hidden in cracks or holes or among boulders.
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.
Little information. Remoteness of breeding sites reduces impacts of human activity.
