THE NATIONAL GEOGRAPHIC MAGAZINE O National Geographic Society DEEP WOODS RESOUND WITH THUNDEROUS DRUMMING OF THE RUFFED GROUSE The male drums with his wings to summon his mates, to challenge other cock grouse to battle, and sometimes just to wear off excess energy. Ranging widely in Canada and the northern and eastern United States, this hardy bird thrives on nuts, grain, seeds, buds, fruit, and insects. During the unexplained "crazy season" in the fall, many RUFFED GROUSE kill themselves by flying into obstacles. As winter approaches, they grow "snowshoes," horny, comblike pro jections on the toes, which help support their weight in deep snow.
