The Connecticut Warbler, nearly everywhere considered a rare bird, 
has been taken, in varying numbers, from Virginia to Massachusetts in 
the east, and from Illinois to Wisconsin in the west, and in nearly all 
the intermediate States. It appears to be more common in the western 
portions of its range, Mr. Nelson regarding it as equally common in 
spring and fall in Northern Illinois. In most places it is particularly 
rare in fall, but, for several seasons, was found by Messrs. Henshaw and 
Brewster, abundant in the vicinity of Cambridge, Mass. It is usually 
found near the ground, in swamp thickets. 
It is given by Dr. Kirtland, in 13388, he having taken a single speci-

the vicinity of Cincinnati, in the spring of 1876. Dr. Darby, of Cleve- 
land, has a specimen which flew in an open window of a house where 
he was visiting JI have taken two specimens, both in the same up- 
land woods; one, a young male, September 16, 1874, was shot from 
a low branch of a young sapling, to which it flew, when alarmed, 
from a thicket of blackberry bushes, a few feet distant. Its actions, 
during the few moments that I observed it, were remarkably Thrush- 
like. It concealed its head behind the trunk of the sapling, and sat 
quiet. in fancied security, while its body was entirely exposed. This 
specimen had the chin and throat soiled whitish-buff, passing insensibly 
into grayish on the auriculars, and brownish-olive on the breast, where 
it formed a tolerably well defined band; other under parts yellow, with 
more olive shading than in the adult; upper parts olive-green, tinged 
with brownish on the head, neck, and upper back. The second specimen
