THE NATIONAL GEOGRAPHIC MAGAZINE ( National Geographic Society LARGEST OF TIE GROUSE, THE SAGE HEN CLINGS TO SAGEBRUSH PLAINS Large flocks of male SAGE HENS (in foreground with female) assemble in earliest spring to croak, strut, and posture. This vainglory is punctuated with frequent vicious fights. These birds, also known as "sage grouse," are found from southwestern Canada to California and Nebraska. At the top is a female COLUMBIAN SHARP-TAILED GROUSE (left) with two males. Much grayer plumage and a more southerly range distinguish the Columbian from the northern sharp-tailed grouse.
