Each forest type attracts its own subset of summer birds. The aspen–birch community supports ovenbirds, red-eyed vireos, veeries, ruffed grouse, black-capped chickadees, least flycatchers, and black-throated green warblers. The same species appear in the aspen–birch–fir forest with the addition of white-throated sparrows, magnolia warblers, yellow-rumped warblers, and winter wrens. The most common overwinterers are black-capped chickadees, gray jays, pine grosbeaks, and hairy and downy woodpeckers. Specific to the pine forests are Blackburnian warblers, hermit thrushes, eastern wood pewees, golden-crowned kinglets, brown creepers, and red-breasted nuthatches.
