its ^Terttest abundance, the coastal 

 area south of Juneau. The number 

 of Ahiskan eaole stomachs that con- 

 tained suiiicient food for the esti-

Aleutian Islands. — Because of the 

 peculiarities of the prey fauna of 

 the bald eagle on the Aleutian 

 Ishmds, the available information 

 on its food habits on those far- 

 Hung islands has been segregated 

 liere. Much of our knowledge on 

 tlie subject rests on the observations 

 made and specimens collected by 

 Glaus J. Murie and his associates in 

 11)36 and 1937 (Murie 1940). Al- 

 tliough the eagle studies were inci- 

 dental to a more comprehensive bio- 

 logical survey of the area, food 

 remnants and ejected pellets of the 

 bald eagle were gathered from 10 

 nests in 1936 and 18 nests in 1937, 



and a total of 399 food items identi- 

 fied therefrom. Collections were 

 nnide at various points from the end 

 of the Alaskan Peninsula to islands 

 near the end of the chain, 700-800 

 miles to the west. Material from 

 the 1936 expedition was examined 

 l)y Cecil S. Williams in "Washing- 

 ton, 1), C, while the remainder was 

 examiiied by Murie, aided (in a few 

 determinations) by the senior au- 

 thor of this paper. 



Table 3, condensed from two ta- 

 bles in the earlier article (Murie 

 1910), and including a few addi- 

 tions from later identifications, re- 

 veals the bald eagle's dominant 

 foods on the Aleutian Islands. Be- 

 cause of the nature of the material, 

 the percentages listed for the differ- 

 ent items have been based on the 

 proportion that the number of in- 

 dividuals of each species bears to
