Early Summer Birds in Yosemite Valley. 



123 



The following list of fifty-five birds contains only those 

 species recognized with certainty by the writer and his 

 wife, and within the valley proper, or along its walls as 

 high as Eagle Peak, or in Little Yosemite. The period 

 of observation extended from May 22d to June I, 191 1 ; 

 at least half of each day was spent in tramping about, 

 though the much-traveled trails were tabooed as far as 

 practicable. 



The beginning bird student will find adequate descrip- 

 tions of all these birds, and additional ones which will 

 doubtless be found to occur in the valley, in Bailey's 

 "Handbook of Birds of the Western United States," 

 (Houghton, Mifflin and Company, 1904).
