The state bird of Pennsylvania, the ruffed grouse (Bonasa umbellus) gets its name from the tufts of black feathers on its neck, which are raised into a ruff by the male during its courtship display. The ruffed grouse has the biggest range of all North American grouse species. The patterning of light and dark on the feathers of the ruffed grouse helps to break up the bird’s silhouette. This is known as ‘disruptive’ or ‘cryptic’ colouration.
