SP. CHAR. Prevailing colors, clear dusky-black above, and pure

white beneath; no buff about the head. Upper parts variegated with

transverse, rather zigzag, spots of yellowish-brown; scapulars with

broad, elliptical, longitudinal medial spots of pure white; wing-coverts

with large rounded, and outer webs of primaries with smaller and more

quadrate, spots of pure white. Breast thickly covered with broad

V-shaped, and the sides with less numerous sagittate, marks of uniform

clear slaty or dusky. Legs densely feathered, the long hair-like

feathers reaching beyond the claws, and completely hiding the toes.

Throat thickly spotted with dusky. No appreciable differences in

plumage between the sexes. _Male_ (31,616, Fort Resolution, Dec. 1862;

J. Lockhart). Wing, 8.60; tail, 4.50, the two middle feathers one inch

longer.

HAB. British America, from Hudson’s Bay Territory, south to northern

shore of Lake Superior, and west to Alaska and British Columbia.

HABITS. The Arctic form of the Sharp-tailed Grouse is found throughout

the Arctic regions, from Alaska southward and eastward to an extent not

fully ascertained. Mr. Dall states that this variety is not uncommon at

Fort Yukon, where Mr. Lockhart found it breeding and obtained its eggs.

It has also been seen some two hundred miles down the river, but it is

said not to be found below the cañon known as the Ramparts. Captain

Ketchum, in his adventurous winter trip from Nulato to Fort Yukon,

is said to have killed several of these birds. Specimens are in the

Smithsonian Museum from Moose Factory and elsewhere along the southern

part of Hudson’s Bay, and it is said to be abundant about Nipigon Lake,

north of Lake Superior.

Mr. Kennicott found the nest of this bird at Fort Yukon, at the foot

of a clump of dwarf willows. It was in dry ground, and in a region in

which these willows abounded and were quite thickly interspersed with

other trees, especially small spruces, but no large growth. The nest is

said to have been similar to that of _Cupidonia cupido_. Mr. Lockhart

also found it breeding in the same region. The nests seen by him were

likewise built on a rising ground under a few small willows.

Richardson assigns as the northern limit of this species the region

of the Great Slave Lake, latitude 61°, and as its most southern point

latitude 41°. It was found in abundance on the outskirts of the

Saskatchewan plains and throughout the wooded districts of the fur

countries, frequenting the open glades or low thickets on the borders

of lakes, especially where the forests have been partially cleared;

perching on trees in the winter, but keeping to the ground in the

summer; and, at all seasons, met with in small flocks of from ten to

sixteen. They are said, early in spring, to select some level place,

where a covey meets every morning and runs round in a circle of about

twenty feet in diameter, so that the grass is worn quite bare. If any

one approaches this circle, the birds squat close to the ground; but if

not alarmed by a too near approach, they soon stretch out their necks to

survey the intruder, and resume their circular course, some running to

the right and others to the left, meeting and crossing each other. These

“partridge-dances” are said to last a month or more, or until the female

begins to incubate. This Grouse rises from the ground with the usual

whirring noise, and alights again at a distance of a few hundred yards,

sometimes on the ground or on the branches of a tree. In winter they

hide in the snow, and make their way with ease through the loose drifts,

feeding on the buds of the willows, larches, aspens, etc. In summer and

autumn their food is principally berries. They are said to lay about

thirteen eggs early in June; the nest being on the ground, formed of

grasses lined with feathers.

The eggs of this variety closely resemble those of the _columbianus_,

but are generally of a decidedly darker ground. They average 1.75

inches in length by 1.28 in breadth. Their ground is a dark tawny-brown

minutely dotted with darker spots of brown.
