ZOOLOGY. 
the 28th of April, 1856. It was shot by my servant, who described it as being excessively 
wild and difficult to approach. 
This is the only specimen of the species I have seen, and I consider it therefore accidental 
west of the Cascade mountains.—S.

Collyrio borealis, Baird, Gen. Rep. Birds, p. 324. 
Sp. Ch.—A bove light bluish ash, obscurely soiled with reddish brown. Forehead, sides of the crown, scapulars, and upper 
tail coverts hoary white. Beneath white, the breast with fine transverse lines. Wings and tail black; the former with a 
white patch at base of primaries and tips of small quills; the latter with the lateral feathers tipped with white. Bill blackish 
brown; considerably lighter at the base. Black stripe from the bill through and behind the eye, but beneath the latter 
interrupted by a whitish crescent. Female and young with the gray soiled with brownish. Length, 9. 85; wings, 4. 50; tail, 
4. 80; its graduation, . 90. 
Length, lOf inches; extent, 14J inches; feet, black; bill, brownish black. 
Eab. —Northern regions, from Atlantic to Pacific; in winter south, through most of the United States. 
The northern shrike is only a winter resident in the Territory, appearing along the coast in 
November and remaining until March. It frequents bushy places, and seems to live chiefly on 
insects. I never saw them attack small birds, though often in company with them.—C. 
I obtained one specimen of this shrike at St. Mary’s valley, Washington Territory, in 1853. 
As a group the butcherbirds are but poorly represented in number in Oregon or Washington 
Territories.—S.

Sp. Ch. —Third, fourth, and fifth quills nearly equal; second and sixth usually about equal, and about . 25 of an inch 
shorter than third; the exposed portion of spurious quill about one-fourth the third. Above greenish olive; the head and 
hind neck ashy, the back slightly tinged with the same. Lores dusky; a white streak from the base of the upper mandible

slate color; bill, brown. 
Hab .—Atlantic to Pacific coast of the United States. 
I did not notice tbe arrival of the warbling vireo, near Puget Sound, until about the middle 
of May, but it was quite common afterwards. Its song, more lively than in other species, was
