THE CONDOR

pearance. The little one seemed ashamed of its juvenile clothes and could be seen 

 sitting on the tent pulling out the old fuzzy feathers as fast as it could. It would 

 grab a piece of down, brace itself and give a hard yank and out came the feather. 

 By this time the hawks began to hop around on the boxes and liked to sit on 

 top of the tent when the sun was shining. They were verj^ sociable and would 

 come into the tent when allowed to do so, and showed much interest in the work 



being carried on, showing es- 

 pecial interest in the bird 

 bodies. Often they would find 

 a roll of cotton or some other 

 soft warm place and nestle 

 down and go to sleep. 



On July 21 the larger bird 

 weighed twenty-six ounces 

 and the smaller one twent}'- 

 five ounces. They seemed to 

 have reached almost their full 

 size and the large one began 

 to fly on this date. He was 

 particularly "sassy" and^was 

 ready to fight anything at any 

 time. 



As the birds were sitting on 

 top of the tent a crow came 

 "cawing" over them. They 

 both let out a defiant duck hawk war cry and did not seem to be in the least 

 afraid. The smaller one died a few days later and from that time on I heard the 

 older one utter the duck hawk yell onl}^ once. He seemed to miss his mate very 

 much and spent most of the time gazing wistfully up into the blue. 



On July 23, or practically six weeks after thej^ hatched, the oldest duck hawk 

 was able to fl}^ and after that I had to keep him tied to a long piece of fish line to 

 keep him from flying away altogether.

SUMMER BIRDS OF THE TUI.ARE I.AKE REGION 



By E. A. GOLDMAN 



THE Tulare L,ake region occupies a depression along the western side of the 

 southern part of the San Joaquin Valley in California. Besides Tulare lyake 

 it may be understood to include the marshy areas from Summit I^ake on the 

 north to Kern Eake and Buena Vista Lake on the south. Summit Lake, perhaps 

 less known than the others, is a small sheet of open water in the delta of Kings 

 River, hemmed in by floating masses of peat and wooded islands. The sluggish 

 currents of various sloughs carry the river waters away in two directions — north- 

 ward to the San Joaquin River and southward to Tulare Lake. 



In the course of field work for the Biological Survey the writer visited the re- 

 gion in the early summer of 1907, remaining from June 18 to July 12. Small col- 

 lections of birds were made at Summit Lake, at various points along the northern
