Range. - The prairies, chiefly west of the Mississippi; north to Manitoba, east to Ohio, and west to Colorado.
This familiar game bird of the west is about 18 inches in length, brownish above and grayish below, with bars of brownish black both above and below. In the place of the ruffs of the Ruffled Grouse, are long tufts of rounded or square ended feathers, and beneath these a peculiar sac, bright orange in the breeding season, and capable of being inflated to the size of a small orange; this is done when the bird makes its familiar "booming" noise. They are very good "table birds" and although they are still very abundant in most of their range, so many are being killed for market, that it has become necessary to make more stringent laws relating to the killing and sale of Pinnated Grouse, as they are often called. They nest anywhere on the prairie, in hollows on the ground under overhanging bushes or tufts of grass. They lay from eight to fifteen eggs having a buffy or olive buff ground color, sparingly and finely sprinkled with brown; size 1.70 x 1.25.
