Dr. Newberry regards this Grouse, when in full plumage, as rather a handsome bird, and much better looking than any figure he has seen of it. It is much the largest of American Grouse, weighing from five to six pounds. The female is much smaller than the male, and is of a uniform sober-brown color. The male bird has a distinctive character in the spaces of bare orange-colored skin which occupy the sides of the neck, and are usually concealed by the feathers, but may be inflated to a great size. The species was not found in the valleys of California, but belongs both to the fauna of the interior basin and to that of the Rocky Mountains, the dry desert country lying on both flanks of this chain. He first found it high up on Pit River, and once came suddenly upon a male in an oasis near a warm spring, which started up with a great flutter and rush, and, uttering a hoarse hek-hek, flew off with an irregular but remarkably well-sustained flight, which was continued until the bird was out of sight. In searching around he soon found its mate, which rose from under a sage-bush with a noise like a whirlwind. This specimen was secured, and these birds were afterwards found to be quite abundant, but very strong-winged and difficult to kill. It was no uncommon thing, Dr. Kennerly states, for him to pour a full charge of shot into them at a short distance, dislodging a quantity of feathers, and yet to have them fly off to so great a distance before they dropped that he could not follow them. He found them only in the vicinity of the sage-bushes, under which they were usually concealed. He afterwards saw them very abundant on the shores of Wright and Rhett Lakes. In one instance he observed a male bird to sink down on the ground, as the train approached, depressing its head, and lying as motionless as a stick, which it greatly resembled. As he moved towards it, the bird lowered its head until it rested on the ground, and made itself as small as possible, and did not rise until he had arrived within fifteen feet of it. West of the Cascade Range it did not occur, and all its preferences and habits seemed to fit it for the occupancy of the sterile region of the central desert. Its flesh is dark and highly flavored with the wormwood. The young, if parboiled and stewed, are said to be quite good; but, on the whole, this Grouse is inferior for the table to any other American species.
Dr. Cooper gives this bird as common in Washington Territory, on the high barren hills and deserts east of the Cascade Mountains, and limited in its range by the growth of the Artemisia tridentata, the leaves of which shrub seem to be the principal part of its food; the flesh tasting so strongly of it as to be unpalatable. He saw none north of the Spokane Plains, the country being apparently too woody. On those plains they were very common. He describes its flight as more heavy and less noisy than that of most Grouse, and when they are started, it commonly extends a long distance before alighting.
Dr. Suckley found the Sage-Cock abundant on the plains of Oregon, near Snake River, on both sides of the Blue Mountains, as also along the line of the Columbia, on the open plains, and on the sage barrens of the Yakima and Simcoe Valleys,—in fact, wherever the artemisia was found. The leaves of this shrub either are preferred or are necessary to its existence, for no other food was found in their full stomachs, even in localities where abundance of grass-seed, wild grain, grasshoppers, and other kinds of food, might be found. This species has apparently the power of going a long while without water. Lieutenant Fleming informed Dr. Suckley that he found them about twelve miles west of Fort Laramie, but they were not seen east of that point so far south. In August, 1853, one was procured about two hundred miles east of the Rocky Mountains. He also observed a small flock on the plains bordering on Milk River, in Nebraska. Near Soda Lake, the sink of the Mohave River, Dr. Cooper met with it, which is without doubt the most southern point at which it has been discovered. Dr. Coues has never met with it in Arizona.
Mr. Ridgway encountered it everywhere in the Great Basin where there was a thrifty growth of the artemisia, which appears everywhere to regulate its existence. He corroborates the accounts given of its heavy, lumbering flight; and when it has once escaped, it flies so far that the sportsman rarely has a second opportunity to flush it. It rises apparently with great effort. He was told by the settlers of Nevada and Utah that the Sage-Hen was never known to touch grain of any kind, even when found in the vicinity of grain-fields. This is attributed to a very curious anatomical peculiarity of the species,—the entire absence of a gizzard; having instead a soft membranous stomach, rendering it impossible to digest any hard food. In a large number of specimens dissected, nothing was found but grasshoppers and leaves of the artemisia.
Two eggs in my cabinet, from Utah, measure, one 2.20 by 1.50 inches, and the other 2.15 by 1.45. They are of an elongate-oval shape, slightly pointed at one end. Their ground-color varies from a light-greenish drab to a drab shaded with buff. They are thickly freckled with small rounded spots of reddish-brown and dark chestnut.
