Distribution:
Breeds in rocky alpine habitats in central Idaho, southwestern Montana, the
Tetons, and the Ruby mountains near Elko, Nevada.
Habitat:
Barren,
rocky or grassy areas with cliffs among glaciers above treeline. Winters in
open areas at lower elevations, sometimes visiting human habitation with feeders.
Diet:
Insects and other
invertebrates in the spirng and summer, seeds and other plant parts in the fall
and winter.
Ecology:
Not truly territorial in that the male follows the female wherever
she goes. Feed on snowbanks at high elevations and glean insects that are too
cold to move. In winter they flock
, with Gray-crowned Rosy-Finches
on exposed ridges and near feeders. At night they roost
in caves, mine shafts,
or in abandoned Cliff Swallow nests.
Reproduction:
monogamous
. Female builds a cup nest
in a cliff crevice where she lays 4-5 eggs. Female incubates
for 12-14 days, then the
altricial
young are fed for an additional
16-22 days by both male and female.
