are, according to Mr. Audubon, in the United States, 

 north of the Ohio. 



Rose-breasted Grosbeak. (Coccothraustes Ludoviciana.) 



F. B. A. 2. p. 271. 



Mr. King obtained a specimen of this charming bird 

 on Lake Winipeg, and has made a note of its irides 

 being red. Audubon and Wilson state them to be 

 hazel. 



The Spotted Grouse. [Tetrao canadensis.) F.B. A. 2. 



p. 347. t. 62. 



This bird ranges from the northern districts of the 

 United States to the extremities of the woods on the 

 banks of the Mackenzie (lat. 68°) ; and from the facility 

 with which it can be killed at certain seasons when game 

 is scarce, is of great service to the Indian hunter. It 

 inhabits thick forests, and particularly swampy places 

 where the black spruce grows, and on this account is 

 called by the Canadian voyagers perdrix de savanne. 

 The leaves of the spruce form its food, which gives its 

 dark-coloured flesh a strong resinous taste. Franklin's 

 grouse, an inhabitant of the acclivities of the Rocky 

 Mountains, and the country to the westward of that 

 ridge, differs from the spotted grouse in the twelve 

 upper tail coverts being broadly tipped with white, and, 

 according to Mr. Douglas, their eggs are also dissimilar. 



The Willow Grouse. (Lagopus saliceti.) F. B. A. 2. 



p. 351. 



This ptarmigan is of still more importance to the
