altogether so shrill and slender as to sound almost like the 

 faint filing of a saw. This species extends its migrations to 

 Newfoundland, according to Pennant. In the month of 

 Tune, Audubon found the nest in Labrador placed about 

 " feet from the ground, in the fork of a small branch, close 

 to the main stem of a fir-tree. It was formed of green and 

 white moss and lichens, intermixed with coarse dried grass ; 

 within this was a layer of bent-grass, the lining, of dark-colored 

 dry moss, looked like horse-hair, and was arranged in a circu- 

 lar direction with great care ; lastly was a thick bed of large 

 soft feathers, — some of them were from Ducks, but most of 

 them from the Willow Grouse. It contained 4 eggs. 



The Black-poll breeds sparingly in northern New England, New 

 Brunswick, and northern Michigan, building chiefly beyond the 

 Laurentian hills, in Quebec and Ontario ; though Dr. L. B. Bishop 

 found it breeding in numbers on the Magdalen Islands, and Mr. 

 J. P. Norris took a number of nests on Grand Menan. It ranges 

 northward to the Barren Grounds and to Alaska, and winters in 

 northern South America.

This common species, to the commencement of winter, in- 

 habits all parts of the United States,"" and probably extends 

 its northern migrations to the forests of Newfoundland. It 

 arrives in Pennsylvania at the close of March and beginning of 

 April, and soon after is seen in all parts of New England, 

 amidst the pine and juniper forests, in which it principally
