Ruffed grouse are named for a series of black iridescent feathers on the sides of the neck called the ruff, which is erected by males to form an ring around the neck during courtship displays.
This forest-dwelling species, favored by upland game-bird hunters, is well known for the drumming of the males during courtship displays in the spring.
It is a common resident throughout most forested regions of the state. It occupies most forests at low to moderate elevations east of the Cascade crest, primarily the east slope of the Cascades from Ft. Klamath and upper Klamath Lake and Blue Mountains, but also forested aspen stands of southeast Oregon desert regions.
