The gray-crowned rosy-finch is
perhaps one of the most elusive of Canadian birds, detectable only by its
melodious warble which resembles that of a goldfinch, or by the in-flight
chattering that can be heard when it moves in flocks.
The plumage of this small songbird helps it to blend into the rocky
surroundings which it inhabits. The gray-crowned rosy-finch can be found
atop mountains well above the tree line, in grassy patches among slopes
and along cliffs in nests of dried grass, rootlets, plant down,
moss and feathers constructed in crevices and under rocks.
These birds are mainly ground feeders that forage for seeds of weeds
and wild plants. During breeding season, they capitalize on the abundance
of insects and switch to a more protein-rich diet. After mating, females
lay eggs in groups of four or five, and incubate them for 12 to 14 days.
Gray-crowned rosy-finches are western birds, summering in the Yukon,
British Columbia and Alberta and, from late fall to early spring, dwelling
in valleys and along the BC coast, as well as on the steppes of Alberta
and Saskatchewan.
