FAUNA OF THE ALEUTIAN ISLANDS AND ALASKA PENINSULA 143 



Females: wing, 113.5 to 127 (120.5) ; exposed oilmen, 27 to 33 

 (30.7) 



The Aleutian sandpiper nests throughout the Aleutian Islands, 

 where it is the common shorebird ; it also nests along the Alaska 

 Peninsula and adjacent islands — at least as far east as Port 

 Moller (Jaques 1930), and undoubtedly all the way to the base

 by Johnson, at Nushagak, July 11 and 18, 1884, and another was 

 taken April 18, 1885 — all these specimens appear to be couesi. 

 There may be some question in regard to the breeding status of 

 this bird on Kodiak Island ; however, it winters there.

The Nesting Period 



Extensive observations on the nesting of the Aleutian sand- 

 piper were possible in 1925, when I spent a season on Unimak 

 Island and the adjacent part of Alaska Peninsula. On April 29, 

 flocks of Aleutian sandpipers (as many as 20 birds) were feed- 

 ing along the lagoon at Urilia Bay. The first mated pairs were 

 noted on May 3; these mated birds had left the shorelines and 

 were nesting on the mossy tundra. By May 7, they had become
