Ruffed Grouse are found in dense, brushy, mixed-conifer and deciduous tree cover, often along stream bottoms. It has been noted that drumming males mostly select mixed hardwood-coniferous forest or pure hardwood forest in association with openings such as clear-cuts, fields, or meadows, and that a shrub layer with vertical structure was more important than one with horizontal structure. species obtained from Ridgely, R.S., T.F.

Maps | Area of Occupancy. As the hardwood component of the forest declines with increasing elevation (due to both a decline in logging intensity and the general natural decrease in hardwoods as elevation increases in Washington), the dominant grouse becomes the Blue Grouse. Amphibians and reptiles of Montana. Breeding Bird Atlas (BBA), other datasets and experts throughout the state, as part of the Washington Gap Analysis Species exhibits moderate age of maturity, frequency of reproduction, and/or fecundity such that populations generally tend to recover from decreases in abundance over a period of several years (on the order of 5-20 years or 2-5 generations); or species has moderate dispersal capability such that extirpated populations generally become reestablished through natural recolonization (unaided by humans).

Male ruffed grouse will perch on logs and flap their wings so fast they become a blur. Redmond. These chickenlike birds eat mostly the needles of fir, spruce, and pine, an aromatic diet that makes them unpalatable to many hunters. The habitats were CommentBreeding Bird Survey (BBS) has relatively low credibility in Montana, but shows a decline of 3.8% per year since 1980 which is a 22% decline over a 10 year time period. Females are intricately scaled with brown, buff, and white. Where they occur with other grouse, Ruffed Grouse are to be found in microhabitats more characteristic of hardwood areas than coniferous areas, and they exist well in managed forest areas.

Mussehl (1971) says they inhabit the denser cover of mixed conifer and deciduous trees and brush, and are often along stream bottoms. There is quite a bit of overlap between the two species however, with Blue Grouse occurring in moderate-elevation forests, and in mixed forests just above the Puget Trough (along with Ruffed). How Climate Change Will Reshape the Range of the Ruffed Grouse Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.

Legend: = Core Habitat = Marginal Habitat. Since the Ruffed Grouse may occur in patches of deciduous vegetation below our mapping resolution in conifer forests, conifer forests were included knowing there may be smaller pockets of habitat suitable for this Grouse.
