COMMON BIRDS : SECOND SERIES.

nest, and utters, when alarmed or excited, a loud, scolding chatter. 
The song, which is often delivered while the male is sitting on the 
eggs, resembles in form that of the Red-eyed Vireo, but is louder, 
slower, and sweeter, though marred by an occasional harsh note. 
The Yellow-throated Vireo is not found in northern New England, 
but from Massachusetts southward it is a common bird. It winters 
outside the limits of the United States. 
Chestnut-sided Warbler. 15. 
[dendrceca pennsilvanica.] 
In the shrubbery that borders all well-kept country roads, and 
in the young growth of forest clearings, the Chestnut-sided War¬ 
bler finds food and shelter. It is easy to find the bird, if one fol¬ 
lows the bright song that sounds at regular intervals from the 
shrubbery, and very easy to recognize the singer from its bright 
and varied markings. The female resembles the male, but has 
duller colors. The song is extremely like that of the Yellow War¬ 
bler, but ends with a more decided wee'-chee. The two birds are 
not likely to inhabit the same places, the Yellow Warbler prefer¬ 
ring the neighborhood of water or the vicinity of man. Besides 
this sharp, emphatic song, the Chestnut-sided Warbler has also a 
looser, weaker one, which for some people is harder to distinguish 
from other Warbler songs. The Chestnut-sided Warbler reaches 
New England early in May, and by the end of the month has built 
in some low bush, often on a blackberry cane, a dainty nest of thin 
bark, mixed with downy substances, and lined with hairs. Here 
are laid four or five eggs, colored, like most of the Warblers’ eggs, 
white with reddish markings. The birds find their insect food in the 
trees and bushes, and occasionally fly out after some winged creature 
that they have disturbed. A few individuals, possibly migrants 
from the north, pass through New England in early October, and 
the winter quarters of the race are in the tropics.
