Part 109

The female sits very close, and rather than leave will sometimes suffer herself to be taken by the hand. In one instance when a nest was approached, the female crouched as much as possible, in the hope that she might not be noticed, which would have happened had not one of the party observed her eye. Her summer plumage was almost exactly of the same color with the soil, and hardly distinguishable from it. The man was within three feet, and, making a swoop, caught her on the nest.

Excepting in 1862, Mr. MacFarlane did not meet with any of this species west of the Swan River, on his various journeys to Franklin Bay. Every season, almost immediately on leaving the woods fringing Swan River, birds began to be seen as far as and all along the Arctic coast. Although constantly found feeding in large numbers on the Barrens, it was always difficult to find their nests. They were most numerous between Horton River and Franklin Bay, and were frequently seen standing singly, or feeding on the ground, or an occasional pair might be seen, but it was seldom any number were observed in company.

Mr. Dall states that this species was not uncommon in the Romanzoff Mountains, northwest of Fort Yukon, but did not know of its being found farther south or west. It was obtained by S. Weston at Fort Yukon, and among the mountains by Mr. McDougal.

The eggs of this species closely resemble those of L. albus, but are somewhat smaller in size. They measure 1.63 inches in length by 1.18 in breadth, varying slightly in size. Their ground is a deep reddish cream-color, nearly covered by large blotches of a reddish-chestnut, giving a beautifully variegated effect to the whole.

SP. CHAR. Male? winter (4,578, Fort Halkett, Liard’s River). Entirely pure white, including the tail. Wing, 6.70; tarsus, 1.00; middle toe, 1.00; bill, .35 by .29.

Summer. Wings, tail, abdomen, crissum, and legs immaculate snowy-white. Ground-color of rest of plumage grayish-white on head and neck and ashy-buff on other portions, finely and rather sparsely sprinkled with black,—more in form of ragged transverse bars anteriorly and on sides. (♀, 16,002, Camp Skagitt, N. W. B., August 16; C. B. Kennerly.)

HAB. Alpine summits of the Western mountains, from lat. 39° in the Rocky Mountains north into British America, and west to the Cascades of Oregon, Washington, and British Columbia.

HABITS. This species was first procured by Mr. Drummond, and described by Swainson in the “Fauna Borealis.” Five specimens were taken on the Rocky Mountains in the 54th parallel, and another, by Mr. MacPherson, on the same chain, nine degrees farther north. They were said to have all the habits of the other Ptarmigans, and to inhabit the snowy peaks near the mouth of the Columbia, as well as the lofty ridges of the Rocky Mountains.

We have but little reliable information in regard to the habits and distribution of this species. It seems to be confined entirely to the range of the Rocky Mountains, and to be found only among their highest points, occurring at least as far to the south as Cochetope Pass, in latitude 39°, and extending north to an undetermined extent. Specimens were procured in 1858 by Captain R. B. Marcy, on his march from Fort Bridger, in Utah, across the Rocky Mountains to Santa Fé. They were met with near the summit of the mountains not far from Cochetope Pass.

Mr. Charles E. Aiken writes me that he has been informed that this bird is common on Snowy Range, in Colorado Territory. He was informed by an old miner, who claimed to have met with these birds breeding near the top of the range in June, that their nest, composed of leaves and grass, is placed on the ground among bushes on hillsides; that the eggs are fourteen in number, of a light bluish-brown, marked and spotted with a darker shade of brown.

Mr. J. A. Allen (Am. Nat., June, 1872) mentions finding, among the snow-fields of the higher parts of the mountains of Colorado, this Grouse as one of the essentially Arctic species that were not met with below the region of snow. The Ptarmigans were quite common, and in the winter descend into the timbered land, where a great number are killed by the miners for food.

An egg, given to Mr. Allen as a genuine egg of this species, was taken on Mount Lincoln, Colorado, by Mr. Arthur Meade. It is of an oblong-oval shape, and measures, as well as its imperfect condition permitted its length to be estimated, about 1.80 inches by 1.20 in breadth. Its ground is a deep ochraceous cream-color, marked with small rounded spots of a deep chestnut. These are pretty uniformly sprinkled over the surface. Except in size, it bears a close resemblance to the eggs of the European Tetrao urogallus.

FAMILY PERDICIDÆ.—THE PARTRIDGES.

CHAR. Nostrils protected by a naked scale. The tarsi bare and scutellate.

The Perdicidæ differ from the Grouse in the bare legs and naked nasal fossæ. They are much smaller in size and more abundant in species. They are widely distributed over the surface of the globe, a large number belonging to America, where the subfamilies have no Old World representatives whatever. The head seldom, if ever, shows the naked space around and above the eye, so common in the TETRAONIDÆ; and the sides of the toes scarcely exhibit the peculiar pectination formed by a succession of small scales or plates.

SUBFAMILY ORTYGINÆ.

CHAR. Bill stout, the lower mandible more or less bidentate on each side near the end.

The Ortyginæ of Bonaparte, or Odontophorinæ of other authors, are characterized as a group by the bidentation on either side of the edge of lower mandible, usually concealed in the closed mouth, and sometimes scarcely appreciable. The bill is short, and rather high at base; stouter and shorter than what is usually seen in Old World Partridges. The culmen is curved from the base; the tip of the bill broad, and overlapping the end of the lower mandible. The nasal groove is short. The tail is rather broad and long.

Synopsis of Genera found in the United States.

b. Head with a crest of a few long narrow, keel-shaped feathers.

=Oreortyx.= Crest-feathers very long, linear; tail scarcely more than half the wings; bill stout; claws blunt, the lateral not reaching the base of the middle claw. Toes of the outstretched foot reaching beyond the tail.

=Lophortyx.= Crest-feathers widening much terminally, and recurved at the ends. Tail nearly or quite as long as wings. Bill rather small. Claws acute, the lateral reaching to the base of middle one. Toes not reaching the tip of tail.

c. Crest soft, full, and tufted; composed of short, broad, depressed feathers.
