Breeds from portions of Alaska and Canada, south to northern Baja California, central highlands of Mexico, Kansas, Pennsylvania, and southern New Jersey. Winters from breeding range, south to Gulf Coast and northern Florida.
Found in forests and woodlands, parks, gardens, and yards in suburban areas. During migration and in winter, found in variety of woodland and forest habitats, in partly-open situations with scattered trees, and in open fields, pastures, and savannas. Preliminary results of Idaho-Montana study suggest species prefers old-growth stands over rotation-aged stands in Douglas- fir/ponderosa pine forests.
Eats seeds (e.g., alder, birch, pine, maple, thistle) and insects.
Bulds saucer-shaped nest in tree. May form loose colonies when nesting. Takes food from foliage, or forages on ground. gregarious. In fall and winter, travels in flocks of typically 50-200 individuals; occasionally, a few siskins will travel in flocks with goldfinches and redpolls.
Female incubates 3-4 eggs (sometimes 5), for 13 days. Nestlings are altricial and downy. Both parents tend young, which leave nest 15 days after hatching. Female sometimes produces 2 broods/yr.
