Habitat and Distribution
The breeding habitat is coniferous and mixed forest across Canada and the western mountainous areas of the US and Mexico. It is a very rare vagrant to the British Isles, with just two records so far.Its range has expanded to the far east possibly due to plantings of maples Manitoba maples and shrubs around farms and the availability of bird feeders in winter. The migration of this bird is variable; in some winters, it may wander as far south as the southern U.S.
These birds forage in trees and bushes, sometimes on the ground. They mainly eat seeds, berries, and insects. Outside of the nesting season they often feed in flocks. Sometimes, they will swallow fine gravel.
The nest is built on a horizontal branch or in a fork of a tree.
