Lagopus albus.
Sp. Char. Bill very stout. Bill as high as the distance from the nasal groove to its tip. Tail always black, narrowly tipped with white; wing (except upper coverts) pure white.
Summer. Male (43,505, Fort Anderson, September 8; MacFarlane). Head, neck, and jugulum deep cinnamon-rufous; whole upper parts (except wings) paler, more fulvous brown, broadly and closely barred with black. Top of head spotted with black, and the jugulum and neck with scattered bars of the same. Wing, 7.50; bill, .40 from nostril, and .35 deep. Female (53,526, Fort Anderson, June, 1865; MacFarlane). Entire plumage (except wings, tail, and legs) fulvous-buff, heavily spotted and barred above, and regularly barred beneath, with black. Wing, 7.20; bill, .40 by .40.
Winter. Entire plumage, except the tail (which is black with a white tip), immaculate snowy-white; shafts of primaries black. Male (34,968, Northwest R., Labrador; D. Smith). Wing, 7.50; bill, .42 by .45. Female (50,060, Nulato, Lower Yukon, April 12, 1867; W. H. Dall). Wing, 7.50; bill, .42 by .42.
Chick (2,648, Fort Anderson, July, 1864). Prevailing color greenish-buff, tinged with sulphur-yellow on the throat and abdomen, and washed with fulvous on the upper parts. A large oval vertical patch of chestnut-rufous, bordered all round by a black line, which, from the occiput, is continued down the nape in a broad distinct stripe of black. On the upper part of the back this stripe bifurcates, and continues in two broad parallel stripes to the lower part of rump, where they again unite. A black stripe across the wing and one through the eye and auriculars.
Hab. Arctic America from Newfoundland to Sitka.
Lagopus albus.
Habits. Richardson regarded this species as an inhabitant of the fur countries from the 50th to the 70th parallel of latitude, being partially migratory within those limits. It was found to breed among the valleys of the Rocky Mountains, on the barren grounds, and along the Arctic coasts. On the approach of winter it collects in flocks, and retires southward as the severity of the weather increases. They remain, however, in considerable numbers as far north as latitude 67° even in the coldest winters. It was found to be tolerably abundant at the 65th parallel all the year, assembling in vast flocks on the shores of Hudson Bay in the winter time. Mr. Hutchins states that ten thousand of these birds have been captured in a single season at Severn River. Richardson adds that in 1819 these birds made their first appearance at Cumberland House, latitude 54°, in the second week of November, and that they returned to the northward again before the beginning of spring. In the winter they are said to shelter themselves in thickets of willows and dwarf birches, on the banks of marshes and lakes, the buds of the smaller shrubs being the principal part of their food at that season. Denuded sandy spots were their favorite resorts in the daytime, but they passed their nights in holes in the snow. When pursued by sportsmen or birds of prey, they often terminate their flight by hastily diving into the loose snow, working their way beneath its surface with considerable celerity. In thick, windy, or snowy weather they were very shy, perching on the taller willows, where it required a sharp eye to distinguish them from flakes of snow. In the summer season they feed chiefly on the berries of the alpine arbutus and other shrubs and plants, which are laid bare by the thaw, and which do not disappear until they are replaced by a new crop. They incubate about the beginning of June, at which time the females moult. The males assume their red-colored plumage as soon as the rocks and eminences become bare, at which time they are in the habit of standing upon large stones, calling in a loud and croaking voice to their mates, which, still in their white wintry garb, are hidden in the snows below. These birds are more usually in motion in the milder light of night than in the broad glare of day.
Captain Blakiston traced this Grouse across the interior from Hudson’s Bay to near the Rocky Mountains, and obtained a single specimen near Fort Carlton. It does not come down every winter, however, so far south on the Upper Saskatchewan. Near Lake Winnipeg, at Fort Cumberland, and to the eastward, they are common every winter, and numbers are obtained from the shores of Hudson’s Bay. Mr. Ross gives this species as common on the Mackenzie. Mr. Robert MacFarlane found it around Fort Anderson, where, he writes, it was always very numerous in that quarter at all seasons, and generally not difficult of approach. During the breeding-season the males were to be found perched upon trees and stumps in the vicinity of the nest, while the female would rarely leave the latter until almost trodden on. They are also said, by Mr. MacFarlane, to assume their summer plumage earlier than the males, differing in this statement from Dr. Richardson’s. Their nest is always on the ground, and consists only of a few decayed leaves placed in a depression. Sometimes other materials, such as hay, moss, feathers, etc., are found. While incubating, the female occasionally sits so close as to allow herself to be caught, rather than leave the nest.
