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 
June, Audubon found the nest in Labrador placed about 
3 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 m 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
