Brown-capped Rosy-Finch
Leucosticte australis
At a Glance
Rosy-finches in general are birds of the Arctic and alpine zones, but this one inhabits the high peaks of the Rockies from Wyoming south to New Mexico. Even where highways take the observer to areas above treeline, this species can be elusive in summer, seeming to favor the most remote and barren cliffs and isolated snowfields. In winter, when the birds move to lower elevations, they are often much easier to find, even coming to feeders in valley towns.

Behavior
Eggs
3-5. White, unmarked. Incubation is by female only, about 12-14 days.
Young
Both parents feed the nestlings. Young leave the nest about 18 days after hatching, and may remain with parents through end of summer and into the fall. 1 brood per year.
Diet
FEEDING. Diet and feeding behavior are very similar to those of Gray-crowned Rosy-Finch
Nesting
At high elevations where this bird nests, snow may cover nesting sites until late June in some years. Birds may be already paired when they arrive at breeding areas. Nest site is in a crevice or hole in a cliff, sometimes a very narrow crevice where the nest is quite inaccessible; sometimes under a rock, in mine shaft, or in abandoned building. Nest (built by female) is a bulky cup of moss, grass, weeds, rootlets, lined with fine grass and sometimes with feathers or animal fur.
Conservation
Conservation Status
Uncommon and local. Its isolated mountaintop habitats are likely to be especially vulnerable to the effects of climate change.
