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.
