Some of the larger species in the range include the red-breasted sapsucker, common ravens, peregrine falcons, the pileated woodpecker, turkey vultures, wood duck, common nighthawks, and the red-tailed hawk. Birds in lower numbers include Vaux's swifts, the endangered spotted owl, bald eagles, the downy woodpecker, hairy woodpeckers, the pine siskin, the hermit warbler, Pacific-slope flycatchers, golden-crowned kinglets, and ruffed grouse.
