42 CALIFORNIA ACADEMY OF SCIENCES. 



Alameda and Contra Costa counties. W. E. Bryant. 

 Rare resident; eggs taken. 



Central California. L. B. Rare winter visitant; 

 probably breeds in Hope Valley, Alpine County, Califor- 

 nia, on the east slope. San Diego County, winter, rare; 

 mountains south of Campo, May, rare; first seen at 

 Summit, Central Pacific Railroad, September 2, 1885. 



37. Falco peregrinus anatum (Bonap.) DUCK HAWK. 



San Diego. L. B. Winter, rare. 



Cooper, 1870. I have found this species along the 

 whole southern coast of California, where it resides con- 

 stantly. 



Henshaw, 1876. Appears to be rather common in 

 southern California, being perhaps most so on the coast. 

 It is numerous on the Santa Barbara Islands, also pres- 

 ent around Kern Lake. 



Alameda and Contra Costa counties. W. E. Bryant. 

 Rare resident. 



Central California. L. B. Rare winter visitant, but 

 perhaps breeds on Butte Slough, Butte County, where I 

 have seen two or more in June. 



Cooper, 1860. Of the western duck hawk I have seen 

 only two pairs, which, in March, 1854, frequented a 

 high wooded cliff at Shoal water Bay. 



British Columbia. John Fannin. Rare summer resi- 

 dent. 



Bendire. Only seen near Malheur Lake attracted by 

 the great number of water fowls of all kinds. 



Ridgway. Observed only at Pyramid Lake and along 

 the lower portions of the Truckee River; at the former 

 locality only a single pair. 



[I have taken the liberty of placing Dr. Cooper's notes 

 on the duck hawk under this species although they were 

 originally under the head of Falco nigriceps Cassin.
