Scientists study rare finch nest in cliffs
- Share via
Following a coffee-shaded bird as it darted from cliffs above the timberline in Wyoming’s Snowy Range, bird-watchers discovered one of the six to eight brown-capped rosy finch nests ever reported.
University of Wyoming zoologist David McDonald examined four chicks tucked into a crevice. The bird nests in Rocky Mountain precipices to avoid squirrels, coyotes, ravens and people.
Researchers know little about the birds, which number about 20,000. The National Audubon Society considers the species at risk due to its limited range. Scientists will study the birds, which are closely related to gray-crowned rosy finches in the Sierra.
