62 CALIFORNIA ACADEMY OP SCIENCES. 



Cooper, 1870. Abundant in the Colorado Valley [Fort 

 Mojave?j. 



[I believe there are no records of its occurrence in 

 California west of the Sierra Nevada, nor of its occur- 

 rence in any part of Lower California, though it is likely 

 to be found in the northeastern part of the latter. By 

 the Sierra Nevada I wish to signify the mountain chain 

 which extends at least as far south as lat. 31° in Lower 

 California and which separates the Colorado Desert from 

 the coast region in California, includes the Cuayamaca, 

 Volcan, San Jacinto, San Bernardino Mountains, and 

 connects with or continues as the Cascade Mountains. 

 A striking feature of these mountains along the head of 

 the Gulf of California is that they are very rocky and 

 steep].

Volcan Mountains. F. E. Blaisdell. — August 21, 

 November 28, 1884, frequently noticed. 



Santa Isabel. W. 0. Emerson. — Seen from January 

 23, 1884, to April 3. 



San Bernardino. F. Stephens. — Rare resident of the 

 valleys and foothills; found nesting in the valley. 



Henshaw, 1876. Ranges from the lower valleys up 

 into the mountains to a height of at least 6,000 feet, 

 where, near Fort Tejon, I found it fairly numerous 

 among the pines, this being the only locality where I 

 found it among the conifers. 



Cooper, 1870. It frequents the oaks and smaller trees 

 almost exclusively, avoiding the coniferous forests. I 

 have not observed it west of the coast range except at 

 Santa Barbara, nor have I seen any around gardens or 

 orchards.
