192 AMERICAN GAME BIRD SHOOTING 



Akutan and Unimak of the Aleutian group. It spends 

 most of the time on higher ground, but at the breed- 

 ing season comes down to the narrow valleys to rear 

 its young. The nest is usually placed in tall grass 

 in some valley or on the open tundra. 



Turner's ptarmigan, another subspecies, is found 

 at Atka, one of the islands of the Aleutian chain. It 

 occurs also on Amchitka Island. The bird is larger 

 than the mainland form, and is quite numerous on 

 these islands. Mr. Turner reports the eggs as from 

 eleven to seventeen in number. The habits of the 

 subspecies are not known to differ from those of the 

 other forms of this ptarmigan. 



Townsend's ptarmigan from Kiska Island, Ever- 

 mann's ptarmigan from Attu Island, 'Chamberlain's 

 ptarmigan from Adak Island, Dixon's ptarmigan from 

 the Sitkan Islands, and Kellog's ptarmigan from Mon- 

 tague Island, complete the list of closely related forms 

 from the Alaskan Islands, where this species seems to 

 have been very easily influenced by local conditions.
