Falconidae. 



Archibuteo lagopus sancti-johannis (Gmelin). 

 rough-legged hawk. 



I have a female shot at Herschel Island, May 21, 1914, by Mr. J. 

 Heard, Jr. It contained an ovary measuring seven eighths of an 

 inch. Mr. Heard found these birds very common at Herschel Island 

 when he took this specimen. 



Mr. Dixon noted this species at Humphrey Point, on May 13, and 

 I saw a single specimen at Demarcation Point, on May 24. 



Haliaeetus albicilla brooksi (Hume). 



eastern gray sea eagle. 



At Cape Shipunski, on May 22, 1913, three eagles were seen, two 

 with white tails, and one in brown plumage. 



Haliaeetus leucocephalus alascanus C. H. Townsend. 



ALASKAN bald EAGLE. 



Bald Eagles were common in southeastern Alaska in April, 1913. 

 Nests were found on Woewodsky Island and on the North Semidi 

 Island. 



Thalassaetus pelagicus (Pallas). 



kamchatkan sea eagle. 



Two very large eagles were seen near the mouth of Avatcha Bay, 

 May 10, 1913. No doubt they were this form. 



The collection contains an adult male acquired by purchase.

peale's falcon. 



We did not see this bird, but secured a pair taken at Copper Island 

 by Dr. I. S. Kalinin, April 10 and 12, 1913, and a female from Bering 

 Island.
