The male makes his familiar drumming sound by rapidly vibrating his wings over a hollow log, while raising his crest and ruff. Drumming is a mating display to attract females. Ruffed grouse stay in small family groups during the summer,  and gather into large flocks in winter.

Habitat:

  • Mixed evergreen and broad-leaved forest and shrubs; most often in broad-leaved woodlands. Their diet consists of young green shoots and leaves, insects and berries during the spring months. In winter they feed on seeds and buds.

Notes:

  • Similar in size to spruce grouse and sharp-tailed grouse, but has larger, fan-shaped tail.
  • Named for the “ruff” of dark feathers along the sides of the neck. (Many people incorrectly call this bird the “Rough” grouse.)
  • Calls with a series of squawks, peeps, and clucks.
  • During spring mating season, the male “drums” his wings over a fallen log, making a characteristic “whump-whump-whump-pump-pump-pump” sound that is often heard by turkey and mushroom hunters.
  • Secretive, cautious birds that flush from the ground with an explosive burst of speed when disturbed.
