Sooty Grouse - Dendragapus fuliginosus

Song: Male's display calls are very low-pitched pulsating hoots like water bubbling down a clogged drain "glooop glooop glooop". Both sexes cluck softly and make grating "grr grr grr" or barking sounds.

Sound: John Neville (Bird Songs of Canada's West Coast); Canada, British Columbia; Salt Spring Island; Adult; Primary Sound;
