The ruffed grouse is a medium-sized bird native to North America, commonly found in forests and woodlands. It has a distinctive ruff of feathers around its neck, which can be raised or lowered, and its plumage is mottled brown and gray, providing excellent camouflage against tree bark and leaves. These birds are known for their unique drumming display during mating season, where males beat their wings against their bodies to create a resonant sound. Ruffed grouse primarily feed on leaves, buds, and berries, making them an important part of their forest ecosystem.
