Sooty grouse

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

Adults have a long square tail, light gray at the end. Adult males are mainly dark with a yellow throat air sac surrounded by white, and a yellow wattle over the eye during display. Adult females are mottled brown with dark brown and white marks on the underparts. Females have longer skinnier necks than males. The males have stouter bodies than the females.
