AW-KIS-COW. Cree Indians. 
This species, heretofore confounded with the Sharp-tail Grouse inhabiting the western portions of the United States, is found in Arctic 
America, . 2 >ientiful around Hudson’s Bay, but never yet, I believe, has it been obtained within the limits of the Union. It is easily 
distinguishable from its near ally, its prevailing black and wEite colors forming a strong contrast to the brownish yellow of the P. 
Columbianus. 
My friend Mr. Kennicott, well known for his successful labors in the various branches of natural history, amid the wilds of the frozen 
North, sent to the Smithsonian Institution many examples of this species, obtained by him in his last expedition. These were the first 
ever in the possession of any American ornithologist, and were named by Dr. Buckley in honor of the gentleman who procured them, as 
they were evidently very different from the bird commonly known as P. Phasianelhis, so abundant in some portions of our Western 
prairies. But, on a more critical examination, it was found that this was the species to which Linmeus had long since given the name 
of Phasianelhis, and, consequently, it of course took precedence over that of P. Kennicotti, which sank into a synonym. 
The present bird resembles its relative in its habits, goes in flocks, and is destitute of any gular sack. It may be described as 
follows ; 
General color black. Top of head black, a few faint marks of rusty toward the occiput, sides of head black, the feathers tijiped 
with white ; those on the side and back of neck tipped with rusty ; throat white, spotted with black. The back is also black, the 
feathers margined with rufous brown; the rump is lighter, caused by the feathers being tipped broadly with grayish; the elongated 
central feathers of the tail are jet black, irregularly crossed with yellowish white and gray. Wings blackish brown, with large white 
spots on all the coverts in addition to the rusty margins of the feathers ; primaries blackish, with white marks on their outer webs. Tail 
sometimes grajdsh at the base, with white tips or pure white. Under parts pure white, with a black Y-shaped mark, near the centre 
of the feathers on the breast and flanks, gradually growing smaller and fainter as they approach the abdomen and vent. The white 
feathers of the legs are hair-like, and extend over the toes quite to the nails. Bill black ; feet dark brown. 
The figures in the plate are of the size of life.
