502 THE WESTERN GOSHAWK. 
breeding form occurring thruout the State; while the more lightly marked 
atricapillus is the form found in winter and during migrations. Mr. Brewster 
refers® two specimens taken by Captain Bendire “in the immediate vicinity 
of Walla Walla during the autumn and winter of 1881-82” to the typical 
form, while doubtfully consigning two others from the same lot to the 
sub-species. Dr. Merrilt refers’ all specimens taken at Fort Sherman, 
Idaho, to this form, and notes that the bird is rather common during the 
migrations and in winter. Mr. Brooks says®: “I have taken both forms 
east and west of the Cascades. The latter [i. e. striatulus] seems to be 
the only form that breeds in southern British Columbia where I have 
noticed it in summer as far east as Arrow Lake. The two sub-species inter- 
grade perfectly.”
