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 

 ^ierra. (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.
