Description
The Dusky Grouse is a large, plump game bird native to western North America's coniferous and mixed forests. Males are known for their elaborate courtship display, fanning their dark tails and inflating colorful air sacs to attract mates. They are generally shy and well-camouflaged, blending into their forest environment.
