Like a slightly larger, longer-billed version of the Purple Finch, Cassin’s Finch is a resident of mountains and conifer forests of the West. It is sometimes found at very high elevations, in the scrubby forest just below treeline, especially in late summer. At other times, little roving flocks wander through the woods, often feeding on buds and seeds high in the trees. The complicated song of the male often includes brief imitations of other birds.

A western counterpart to the Scarlet Tanager, this species occurs in summer farther north than any other tanager — far up into northwestern Canada. Western Tanagers nest in coniferous forests of the north and the high mountains, but during migration they may show up in any habitat, including grassland and desert; the bright males often draw attention by pausing in suburban yards in late spring.
