Calypte anna (Lesson) 

 Anna Hummingbird 



Nowhere abundant, though observed and found breeding in 

 various parts of the mountains. Apparently most numerous on 

 the northern slopes of the range, where they were seen at Cab- 

 ezon (one bird, May lt>>. in some numbers at Schain's Ranch, 

 June 16-30, and occasionally at Puller's Mill, June -'>1 to July 6. 

 About the summit of Santa Rosa Peak, the last week in .June, 

 several were noted. These were probably wanderers Prom below, 

 but others were seen about half way up the mountain, at the 

 Garnet Queen .Mine (altitude 6000 feet), and at this point the 

 species was breeding. A nest was found here, built on the 

 branching limit of a golden oak, overhanging the trail, of the 

 usual structure and covered with lichens. This nest contained 

 t wo young on -I une 26. 



In Strawberry Valley, in July, some were encountered from 

 time to time, bul they were not abundant. A single bird was 

 taken in Hound Valley, July 9. Al Hemel Lake. August 5 to 15, 

 and on Thomas .Mountain. Augusl 16 21, they were seen daily. 

 At Dos Palmos, Augusl '_'•"> i'7. a few were noted along the creek 

 bottom, though the species had not been seen here on our pre- 

 vious visits early in the summer.

Rufous Hummingbird 



After the first week in July many hummingbirds of this and 

 tin 1 closely related species. S. alleni, were seen in the higher parts 

 of the mountains, and during the remainder of our stay here. 

 nearly two months, they continued to he numerous. The two 

 species are so nearly alike thai it is ordinarily impossible to dis- 

 tinguish them in life, and we were unable to ascertain their 

 relative abundance; but of the specimens obtained the majority 

 are 8. rufus. There can be no doubt that neither breeds in the
