Bonasa is a genus of birds commonly known as grouse, which are part of the family Phasianidae. These birds are primarily found in North America and are known for their distinctive plumage and strong, stocky bodies. The most recognized species within this genus is the ruffed grouse, which is often associated with forested habitats. Grouse are ground-dwelling birds that are well-adapted to their environments, using their camouflage to blend in with the forest floor. They are known for their unique courtship displays, where males perform elaborate rituals to attract females. Bonasa species primarily feed on seeds, berries, and leaves, making them important for the ecosystem.
