SYLVICOLID^E — THE WARBLERS. 271 



between the 8tli and the 24th of May, and all built on branches of the red 

 pine and near tlie top. Several nests of this Warbler, found in Lynn, Mass., 

 by Mr. George 0. Welch, are alike in their mode of construction, and differ 

 in their materials from other accounts. They are all somewhat loosely put 

 together, and are composed externally of fine strips of the bark of the red 

 cedar, fine inner bark of several deciduous trees, dry stalks of plants, the 

 exuviae of insects, and fine dry grasses. The cavities of these nests, which 

 are comparatively large and deep, were lined with the fur of the smaller 

 mammals, the silky down of plants, and feathers. A few fine wiry roots 

 were also intermingled. These nests are about two and a half inches in 

 height and three in diameter. 



The eggs of this Warbler are of a rounded oval shape, have an average 

 length .of .72 of an inch, and a breadth of .55. They resemble in size and ap- 

 pearance the eggs of the D. castanea, but the spots are more numerous, and the 

 blotches larger and more generally distributed. The ground-color is a bluish- 

 white. Scattered over this are subdued tintings of a fine delicate shade of 

 purple, and upon this are distributed dots and blotches of a dark purplish- 

 brown, mingled with a few lines almost black.

This species is only known from the description of Wilson, Vieillot, and 

 Audubon, and we are not aware that a specimen is to be found in any collec- 

 Lion. If described correctly, it appears different from any established species, 

 although the most nearly related to D. pinus, which, however, differs in the 

 absence of a yellow frontlet, in having a greener back, less distinct streaks 

 beneath, and in the' white of the anal region. 



Habits. Whether the Blue Mountain Warbler is a genuine species or an 

 unfamiliar plumage of a bird better known to us in a different dress is a
