ZOOLOGY. 
This bird replaces the pinnated grouse in the western country. We first noticed the species 
in Nebraska, near Fort Union, at the mouth of the Yellowstone river. From that point to the 
Cascade mountains of Oregon and Washington Territories the species is exceeding abundant 
wherever there is open country and a sufficiency of food. In certain places they are in great 
numbers in the autumn, congregating in large flocks, especially in the vicinity of patches of 
wild rye, and more recently near settlements where there are wheat stubbles. They resemble 
the pinnated grouse in habits, and are good both for the table and for sport. In places where 
they are numerous they may frequently be found on cold mornings in the autumn or early 
winter perched on fences or leafless trees, sunning themselves in the early sunlight. 
At Fort Dalles, on the 1st of April, 1855, a young bird scarcely two days old was brought to 
me. This early incubation would lead us to suspect that the species, in favorable situations, 
has two or more broods during the season. The young bird above mentioned was confided to 
the matronly care of a hen with a young brood of chickens, but the young grouse, not under¬ 
standing the kindness of its foster parent, ran and hid itself as soon as possible, and probably 
perished that very night from cold. 
The settlers on the Upper Columbia speak of a “gray grouse,” which is probably nothing 
else than the full-grown young of the present species in their first plumage.—S. 
Note. — I have occasionally heard of a grouse which “turns white in winter” that is said to 
be found on Mount Rainier, one of the lofty snow peaks of the Cascade range. Dr. Townsend 
also mentions a Ptarmigan in his list of Oregon birds. All the efforts of myself and friends 
have thus far proved unsuccessful in obtaining a specimen.—S. -

The ruffed grouse, partridge, or pheasant, as it is most commonly called in this Territory, is 
very abundant everywhere about the borders of woods and clearings. It is common near the 
forests east of the Cascade mountains up to the 49th degree. These birds vary considerably 
in plumage there, a pale grayish hue predominating ; while west of the mountains they are all 
of a very dark brown. There seems, however, to be no difference in their habits or cries from 
those of the same bird elsewhere.—C. 
The western ruffed grouse is abundant in the timbered districts throughout Washington and 
Oregon Territories. In habits they are identical with the same bird east. Owing to the mild¬ 
ness of the season in the vicinity of Fort Steilacoom the males commence drumming as early as 
January, and in February I have heard them drumming through the whole night. In autumn 
these grouse collect in great numbers in the crabapple thickets, near the salt marshes, at the 
mouths of the rivers emptying into Puget Sound. Here they feed for about six weeks on the 
ripe fruit of the northwestern crabapple, the Pyrus rivularis of Nuttall.—S.
