The dappled, grayish or reddish Ruffed Grouse is hard to see, but its “drumming on air” display is a fixture of many spring forests. It can come as a surprise to learn this distant sound, like an engine trying to start, comes from a bird at all. This plump grouse has a cocky crest and a tail marked by a broad, dark band near the tip. Displaying males expose a rich black ruff of neck feathers, giving them their name.
