Ruffed Grouse

A male Ruffed Grouse (Bonasa umbellus) displays its umbrella-like ruff of feathers in the snow. To encourage courtship the grouse engages in "drumming", a non-vocal acoustic display, that involves rapid wing-beating to create a low frequency sound which can be heard for over 500m. When an interested hen approaches, he then extends his feathers into a spectacular ruff as seen in this shot. Cariboo Mountains, British Columbia, Canada
