COUES ON BIRDS OF DAKOTA AND MONTANA. 593 



List of specimens — Con tinned. 



JUNCO HYBMALIS, {Linn.) ScL 



Eastern Snowbird. 



The Snowbird appeared along the Mouse Eiver about the middle of 

 September in troops, as usual, and at once became abundant. I had 

 expected to find it breeding on Pembina and Turtle Mountains, and 

 still judge it likely that it does so, though it did not come under my ob- 

 servation. It may not be generally known that in the Eastern States 

 it breeds as far south as Virginia and the Carolinas, if not still farther. 

 While on the South Virginian Alleghanies, in the summer of 1875, at 

 an altitude of about 5,000 feet, I scared a female off her nest, which 

 contained four eggs. This southerly breeding-range in the mountains 

 explains the sudden appearance of the birds upon the first cold snap in 

 October. While in the Eocky Mountains, in August, 1874, I expected 

 to find either this species or J. oregonus, but none appeared in the 

 vicinity of our camp. The Mouse River specimens seem to be pure 

 hyemalis, though the Zonotrichia of this same locality is Z. intermedia, 



not Z. leucophrys.
