spruce grouse facts

The spruce grouse (Canachites canadensis), also known as Canada grouse, spruce hen or fool hen, is a medium-sized grouse closely associated with the coniferous boreal forests or taiga of North America. It is the only member of the genus Canachites. It is one of the most arboreal grouse species, fairly well adapted to perching and moving about in trees. When approached by a predator, it relies on camouflage and immobility to an amazing degree; for example, letting people approach within a few feet before finally taking flight. Races vary slightly in plumage, especially in the tail pattern and in the extent of white on the underparts, but in general adult males are mainly grey above and black below, with white spots along the side, and a red patch of bare skin over the eye called the "eyebrow comb". This red eyebrow comb, should not be confused by a similar yellow marking found on other species of grouse including, but not limited to, sharp-tailed and dusky grouse. Adult females are mottled brown or mottled grey with dark and white bars on the underparts. Juveniles resemble females. Females may be confused with ruffed grouse but they have a dark tail with a pale band at the end and they do not erect their crown feathers when alarmed the way ruffed grouse do.
