t^The Connecticat 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 1338, he having taken a single speci- 

 men. Mr. Langdon mentions a single specimen, taken by Mr. Dury, in 

 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. I 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-bufi', 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 j upper parts olive-green, tinged 

 with brownish on the head, neck, and upper back. The second specimen
