TURNER’S PTARMIGAN. 
Ne inhabitant of the western part of the Aleutian 
chain, this bird is quite numerous on Atka, Am- 
chitka, and Attu islands. It was discovered by Mr. 
Turner, who has furnished all that is known about it. 
He says that he was struck with its great size, shape of 
the bill, and length of claws, and it frequents the low- 
lands and hills of the western islands, and builds its nest 
among the rank grasses near the beach. This is care- 
lessly made of dried grass and similar materials, and the 
eggs, varying in number from eleven to seventeen, are 
darker in color than those of the Rock Ptarmigan, and 
slightly smaller than those of the Willow Grouse. In 
habits it resembles the first species. On account of 
the number of foxes on Attu this bird frequents higher 
elevations than it 1s accustomed to do on the other 
islands. The natives assert that this Ptarmigan is also 
found on Agattu and, on account of the absence of foxes, 
is quite numerous on that island.
