Dusky grouse

The dusky grouse (Dendragapus obscurus) is a species of forest-dwelling grouse native to the Rocky Mountains in North America. It is closely related to the sooty grouse (Dendragapus fuliginosus), and the two were previously considered a single species, the blue grouse.

Their breeding habitat is the edges of conifer and mixed forests in mountainous regions of western North America, from southeastern Alaska and Yukon south to New Mexico. Their range is closely associated with that of various conifers. Their nest is a scrape on the ground concealed under a shrub or log.

These birds forage on the ground, or in trees in winter. In winter, they mainly eat fir and douglas-fir needles, occasionally also hemlock and pine needles; in summer, other green plants (Pteridium, Salix), berries (Gaultheria, Mahonia, Rubus, Vaccinium), and insects (particularly ants, beetles, grasshoppers) are more important. Chicks are almost entirely dependent on insect food for their first ten days.

Males sing with deep hoots on their territory and make short flapping flights to attract females. Females leave the male's territory after mating.
