30 CALIFORNIA ACADEMY OF SCIENCES. 



25. Accipiter velox rufilatus Ridgw. WESTERN SHARP- 

 SHINNED HAWK. 



San Diego. L. B. Tolerably common winter visitant. 



Volcan Mountains. W. 0. Emerson. Seen Febru- 

 ary 22. 



Volcan Mountains. F. E. Blaisdell. From August 

 21 to November 28, not common. 



Cooper, 1870. They probably breed more generally 

 towards the southern and lower parts of the State than 

 that species ( A. cooperi), as I have seen a few of them 

 (or perhaps A. mexicanus), in the warmer months. 



Henshaw, 1876. A common resident throughout 

 southern California. 



L. B. Common during summer months in the upper 

 Sierra. (Birds Central Cal., 1879). My later observa- 

 tions are greatly at variance with the statement of 1879. 

 During the summer of 1885, nearly all of which I spent at 

 the Summit of the Central Pacific Railroad, altitude 7,000 

 feet, and upward, I saw but a single individual, a fine 

 adult male, shot July 4. About September 15, it became 

 common; still more so about October 1. It may be a 

 common summer resident in a very few localities in 

 central and southern California, especially in mountains 

 having the height of Mount Whitney where Mr. Hen- 

 shaw probably saw it. 



Alameda and Contra Costa counties. W. E. Bry- 

 ant. Tolerably common winter visitant. 



Haywards. W. 0. Emerson. March 21, 1884, last 

 seen; first seen in fall, August 28. 



Berkeley. T. S. Palmer. March 9, 1885, last seen. 

 Tolerably common winter visitant. In 1886, seen March 

 7 and April 12. 



Willamette Valley. O. B. Johnson. Moderately com- 

 mon nesting in trees.
