BRITISH COLUM 
BIA AND HYPOTHETICAL LIST. O75 
Recognition Marks.—Crow size: rufous shoulder distinctive; underparts usually rich 
red; averaging a little smaller than Swainsoni. 
Nesting.—Nest-: in trees, of sticks, sometimes lined with bark strips and the like. 
Eggs: 3-5, pale bluish white, with a rough or chalky surface, and spotted or blotched with 
rufous or yellowish brown: occasionally unmarked. Avy. size, 2.14 X 1.67. 
General Range.—Western Texas to the Pacific, north, regularly, to Oregon, less com- 
monly to British Columbia; south to Lower California. 
Occurrence in British Columbia.—i have twice seen undoubted adults of this Buzzard 
at Chilliwack but have been unable to take a specimen. The coloration of the tail and the 
under surface of the wings is of a very conspicuous pattern and when the bird is seen 
sailing overhead its identification js easy to one acquainted with the Eastern form. 
Occurrence in Washington.—Presumptive as above. Also tentative records for Fast- 
side. 
B. C. & H. No. 14. 
WHITE GYRFALCON. 
A. O. U. No. 353. Falco islandicus Brunn. 
Description.—Adult: General color pure white, unmarked on head and underparts, or 
with mere traces of blackish on crown and flags; remaining upperparts marked, barred or 
transversely spotted in variable pattern with slaty black—much like the Snowy Owl in this 
regard. Bull bluish; cere, eyelids and feet yellow; iris brown. Young birds are still white 
but are marked more heavily with dark brown, chiefly in lengthwise pattern, Length of

15.50-16.50; tail 10.00. 
General Range.— Arctic regions, including Arctic America and Greenland; wandering 
south in winter to Labrador, Maine and British Columbia 
Occurrence in British Columbia.—A fine adult male was brought to me at Comox in 
December, 1903. It had been killed by a boy with a “22” rifle on the 4th of the month. 
B. C. & H. No. 15. 
RICHARDSON’S GROUSE. 
A. O. U. No. 207 b. Dendrapus obscurus richardsonii (Dougl.). 
Description.—Similar to D. 0. fuliginosus (q. v. p. 571) but somewhat lighter in 
coloration, the female also with less of tawny; the terminal gray of the tail (in both sexes) 
reduced or wanting. 
General Range.—Rocky Mountain region of the northern United States and British 
Columbia, shading into D. obscurus in southern Idaho and Wyoming, and into D. 0. 
fuliginosus along western boundaries of range. 
Occurrence in British Columbia.—All specimens taken east of the Cascades are re- 
ferred to this form. 
Supposed Occurrence in Washington.—We should expect to find the Richardson 
Grouse the prevailing form in the Kalispell Range and in the Blue Mountains, but further 
study is necessary to elucidate this point.
