Ruffed Grouse

Bonasa umbellus

The Ruffed Grouse is the most widespread and common grouse, and can be found throughout much of Canada, the extreme northern U.S., and higher elevations in the U.S.  An extremely low-pitched "drumming" sound is given by the male in spring, and can be heard over half a mile away.  Two color morphs exist, the more common gray morph, and the red morph (which is found primarily in the Appalachians, and the Pacific Northwest).  

Habitat: Can be found in a variety of forest types, but generally prefers mixed forests of conifer (for shelter) and deciduous (for foraging).  On occasion they can be found in pure conifer forest.

Diet: Omnivorous.  The majority of the diet is plant material, including seeds, berries, leaves, buds, flowers, and fresh shoots.  They will also eat insects, spiders, snails, and occasionally small reptiles or amphibians.

Nesting: May through July

Song: Ruffed Grouse Call.  

Migrations: A semi-permanent resident, with birds making short moves between more open areas during breeding season to denser cover in the winter.

Status: Generally stable throughout its range, with natural local population fluctuation.
