The Purple Finch, a sexually dimorphic species, is moderately common across the northern United States, southern and central Canada, and the west coast of North America. The male, with its complex warbling song and raspberry red coloration, is one of the more conspicuous birds in its range. The female, by contrast, is an inconspicuous, drab, sparrow-like bird. Primarily an inhabitant of moist coniferous forests during the breeding season, this finch also breeds in mixed forest, in ornamental plantations, and in clearings associated with bogs. During the winter, it ranges throughout much of the eastern United States and southern Canada and migrates into lower-elevation areas in the west. It feeds almost exclusively on buds and seeds and is frequently observed at bird feeders.
