BRITISH COLUMBIA AND HYPOTHETICAL LIST. 975 



Recognition Marks. — Crow size; rufous shoulder distinctive: imderparts usually rich 

 red; averaging a little smaller than Szcainsoiii.

General Range. — Western Texas to the Pacific, north, regularly, to Oregon, less com- 

 monly to British Columbia; sfiuth tn 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 wdien the bird is seen 

 sailing overhead its identihcatinn is easy to one acquainted with the Eastern form. 



Occurrence in Washington. — Presumptive as above. Also tentative records for East- 

 side.

 ferred to this form.
