The highly camouflaged Ruffed Grouse is more often heard than seen, as it noisily bursts through the trees when startled. In spring, males display by beating their wings to create a low, rhythmic drumming sound.

Ruffed Grouse
The Ruffed Grouse is a widespread year-round resident of Canada's deciduous and mixed-wood forests, with a range spanning from Yukon and British Columbia to Newfoundland and Labrador. The Canadian population of approximately 15 million individuals represents over 80% of the global breeding population and a very high responsibility for Canada. Both the Breeding Bird Survey and the Christmas Bird Count indicate that the population has shown little overall change since about 1970. Although the reliability of each survey is only medium, confidence in status is high because the trends agree. The national population of Ruffed Grouse is within its goal range.
The best source of information on the population status of Ruffed Grouse is the Breeding Bird Survey (BBS). Although the northernmost portion of its range is poorly covered, precision of trends is high. The national BBS trend indicates a long-term trend of little change in abundance since the early 1970s, with a slight increase over the past decade. Little change has occurred in most Canadian Bird Conservation Regions where reliability is at least medium, but moderate declines have been observed in the Prairies, Pacific Coast and south-central British Columbia. The Christmas Bird Count (CBC) also provides data on Ruffed Grouse with medium reliability, although at a time of year when there is less vocalization. Consistent with the BBS, CBC data also show little change in population size across Canada.
The goal for Ruffed Grouse is to maintain its population at or above the level it was at in the early 1970s, based on the Breeding Bird Survey. Recent data show that the population is within its goal range.

The highly camouflaged Ruffed Grouse is more often heard than seen, as it noisily bursts through the trees when startled. In spring, males display by beating their wings to create a low, rhythmic drumming sound.
Ruffed Grouse is observed uniformly throughout the year in Canada. A slight drop in summer may represent more reclusive behaviour during the breeding season.
