Numerous species of songbirds extract seeds from Douglas-fir cones or forage for seeds on the ground. The most common are the Clark's nutcracker, black-capped chickadee, mountain chickadee, boreal chickadee, red-breasted nuthatch, pygmy nuthatch, red crossbill, white-winged crossbill, dark-eyed junco, and pine siskin. Migrating flocks of dark-eyed juncos may consume vast quantities of seeds and freshly germinated seedlings. Woodpeckers commonly feed in the bark of Rocky Mountain Douglas-fir. Blue grouse forage on needles and buds in winter; they and other birds rely heavily on Rocky Mountain Douglas-fir communities for cover.
