This video from the USA says about itself:

Male Ruffed Grouse performs his drumming display on a resonant, fallen log in the forest. Drumming announces a male’s territory and his desire for a mate. Ruffed Grouse thrive in young forests. Wildfires once created that type of habitat. The ruffed grouse (Bonasa umbellus) is a medium-sized grouse occurring in forests from the Appalachian Mountains across Canada to Alaska. It is non-migratory. It is the only species in the genus Bonasa.
The ruffed grouse is sometimes incorrectly referred to as a “partridge“, an unrelated phasianid, and occasionally confused with the grey partridge, a bird of open areas rather than woodlands.
