Two nests were found, one at the Garnet Queen Mine, June 

 27, containing three young in natal down, the other in Straw- 

 berry Valley, July 9, also with young. The first, placed in a 

 golden oak, thirty feet up, was a rather bulky structure, built 

 of sticks and crooked twigs, and lined with cedar bark. The 

 female parent had been shot two days previous to the discovery 

 of the nest, but the male bird had evidently since kept the young 

 supplied with food, for in the nest were two headless and care-

The Strawberry Valley nest, also in a golden oak. was similar 

 to the first one. 



Buteo borealis calurus Cassin 

 Western Red-tailed Hawk 



A common species encountered at every part of the range 

 visited by our parties, except at the very highest altitudes above 

 iH Mil i feet. Individuals were seen circling over the desert at the 

 mouth of Palm Canon, and at the upper limit of Transition, 

 just below Round Valley. No nests were found, but full grown 

 young, two or three together, attended by the old birds, were 

 seen ;it Keiiworthy on June 5. and near Vandeventer Flat, June 

 25 and July 2. 



No specimens were preserved. 



Buteo swainsoni Bonaparte 

 Swainson Hawk 

 A dark-colored hawk, doubtfully identified as of this species, 

 was seen at Kenworthy. May 22. At Hemet Lake, August 7, two 

 were seen under circumstances permitting of absolute recognition. 

 though neither was secured. One was very dark colored, the 

 other in the light phase, showing the white throat and dark 

 pectoral band peculiar to the species. 



Aquila chrysaetos (Linnaeus) 



Golden Eagle 



From the number of birds seen it seemed probable that 



there were several pairs of eagles breeding in the region covered 



by us. Individuals were observed many times, at the San Gor-
