Black Grouse - Tetrao tetrix

Black Grouse | North Wales
Canon 800mm f5.6 for 1/1600th @ iso800

Even at shutter speeds in excess of 1600th of a second the Black Grouse fights can be hard to capture.

The bird on the left of the photograph has taken the upper hand and with a beak full of feathers is about to send the bird on the right off to the outer edges of the lek.
