Although the loud drumming can be heard a quarter of a mile away, spotting the slow movements of the Ruffed Grouse might take a little patience during quiet walks. The grouse feed almost exclusively on vegetation and in the fall, acorns and soft fruits are a main source. In the harsh winter, their food becomes buds and twigs from aspen, willow and birch as they are able to digest foods high in cellulose.
