THE CONDOR 



Vol. XIX 



27. Accipiter cooperi. Cooper Hawk. Occurs sparingly throughout the county. 

 One was seen near Spencer, July 18, and one near Small, August 11. 



28. Buteo borealis calurus. Western Red-tail. One pair observed in Little Dry 

 Creek Canyon, June 19. Probably nesting. 



29. Buteo swainson i. Swainson Hawk. Fairly common throughout the county. 

 Seen most frequently along low foothills and over sage plains, early in the morning and 

 late in afternoon, in search of small rodents. 



On the first of August I found two dead weasels near the edge of a cultivated field 

 on the Burnside Ranch, near Spencer. I had often seen Swainson Hawks circling low 

 over the fields, and concluded that the weasels were killed by the hawks by mistake, as 

 they probably would not be desirable as food.
