THE BLACK-THROATED BLUE WOOD- WARBLER. 
Sylvicola canadensis, Linn . 
PLATE XCY. — Maze and Young. 
I have met with this species in every portion of the Southern and Western 
States, where, however, it is seen only in the early part of spring and in 
autumn, on its passage to and from its summer residence. In South Carolina 
it arrives about the 25th of March, and becomes more abundant in April ; 
but it has left that country by the 10th of May. During its stay there, it 
keeps in deep woods, where it may be seen passing among the boughs, at a 
height of from ten to twenty feet from the ground. 
Proceeding eastward, we hnd it more numerous, but residing only in the 
depths of the morasses and swampy thickets. 1 saw many individuals of the 
species in the Great Pine Forest of Pennsylvania, after which I traced it 
through the upper parts of the State of New York into Maine, the British 
Provinces, and the Magdeleine Islands, in the Bay of St. Lawrence. In 
Newfoundland I saw none, and in Labrador only a dead one, dry and 
shrivelled, deposited like a mummy in the fissure of a rock, where the poor 
bird had fallen a victim to the severity of the climate, from which it had 
vainly endeavoured to shelter itself. 
I am indebted to the generous and most hospitable Dr. MacCulloch of 
Halifax for the nest and eggs of this Warbler, which had been found by his 
sons, who are keen observers of birds. The nest is usually placed on the 
horizontal branch of a fir-tree, at a height of seven or eight feet from the 
ground. It is composed of slips of bark, mosses, and fibrous roots, and is 
lined with fine grass, on which is laid a warm bed of feathers. The eggs, 
four or five in number, are of a rosy tint, and, like those of most other Syl- 
via}, scantily sprinkled with reddish-brown at the larger end. Only one 
brood is raised in a season. The young, when fully fledged, resemble their
