These birds feed mainly on vegetation, but also on insects, especially when feeding young. Several of the forest-living species are notable for eating large quantities of conifer needles, which most other vertebrates refuse. In all but one species (the Willow Grouse, called Willow Ptarmigan in America), males are polygamous, and many species have elaborate courtship displays. These heavily built birds have legs feathered to the toes. }}
