with an entrance on the side, and is composed principally of hanging mosses.” Capen says: “ Nests are 
purse-shaped, having a small hole for entrance at the top or side. They are composed of hanging mosses 
and lichens, with a slight lining of pine grasses and a few hairs, occasionally without any lining 
whatever. They are usually placed near the end of a branch in a hemlock, cedar, oak, or old orchard 
tree, from ten to fifty feet from the ground.” 
EGGS: 
The same writer continues: “Eggs are four in number, and rarely five. They are white in ground- 
color, finely spotted with light reddish-brown, intermingled with lilac, chiefly about the crown; others 
quite heavily blotched, and often tending to form a ring about the crown. They are usually laid the 
first week in June, and measure about .62 by .43 of an inch.” Davie gives their size from .62 to .65 in 
long-diameter by .49 to .52 in breadth. Maynard gives the same dimensions as from .66 to .70 and .48 
to .50 of an inch. A set of four eggs before me measures as follows: .62 x. 51, .63 x .52, .63 x .50, and 
.62 x .48. The ground-color of the shell is pure, glossy white. About the base, two of the eggs are 
spotted and speckled plentifully with very dark brown, almost black; about two-thirds of these marks 
are beneath the surface, some deeply, others but slightly, so that there are several shades of brown, 
becoming lilac in the deepest laid marks, the balance of the eggs being but very sparingly speckled. 
The other two eggs contain several blotches at the crown; otherwise they are similar. 
REMARKS : 
Plate LXVIII, Fig. 3, represents three eggs of the Blue Yellow-backed Warbler, from Eastern 
New York. They are of the common sizes, shapes, and markings. There is but little doubt that this 
Warbler builds in Ohio, though I can find no nest and eggs in anv of the local cabinets. It has been 
seen in late June in the central part of the State, and I have in my possession a nest and two eggs 
from near Mt. Sterling which probably belong to this species, though the materials of construction are 
very dissimilar from that of the eastern nests. It contains a few threads of long gray lichen or tree 
moss of some kind, and numerous wiry threads of vegetable fibre. In appearance it resembles a 
Baltimore Oriole’s nest, but is much smaller.
