Habitat. — Arctic America from Newfoundland to Sitka. Mr. 0. J. Bampton, 

 Registrar of Algoma, also reports this bird as a rare winter visitor about Sault 

 Ste. Marie. Mr. Alexander H. Taylor of Ottawa, also reports that some winters 

 it may frequently be seen on the market there, having been brought in by the 

 hunters from the back country. 



The peculiar change of plumage of these birds is a provision of nature shown 

 in the covering of many of the birds and animals of the Arctic regions, as the 

 Arctic fox, hares, leemings, owls, etc. It enables the defenceless ones to escape 

 more readily the observation of their many enemies and the foxes, bears, owls, 

 etc., the more readily to approach their prey. 



This Grouse is said to be quite equal, as a game bird, to tbe Scotch Grouse, 

 which it is not unlike. As an article of food they are considered equal to any 

 other of the members of this family.
