isli-green, tinged with ash on crown and sides of head. Yellow beneath, with throat and upper breast, ashy, becoming

 northward, wintering south of our limits. DIMENSIONS. Length, 5'25; stretch, 9'00; wing, 3'00; tail, 2'28; bill, '40; tar- 

 sus, -80. 



HABITS. 



The munitions of (he Connecticut Warblers are quite singular, for although it is one 

 of the rarest birds which are to be found in Eastern Massachusetts, during spring, in au- 

 tumn, it is quite common, frequenting swampy thickets, when it lias much the same hab- 

 its as the Water Thrush. At this time, the note is a low chirp, and I have never met with 

 this species in spring.

 in number,- oval in form, white in color, dotted with reddish-brown. Dimensions from '50 x '70 to - 55x'72. 



HABITS. 



The Kentucky Warbler is quite rare in the Eastern of the Middle States, and does 

 not occur in New England at all, but the great strong-hold of the species appears to be 

 in the West, along the Mississippi River. I have never met with this bird living, so can 

 give nothing new relative to its habib.

 number, elliptical in form, white in color, spotted and blotched with reddish-brown and lilac. Dimensions from 'GOx'HO 

 to -07 x <J5. 



HABITS. 



The Yellow-breasted Chats appear to be somewhat local in distribution; thus, I did 

 not find them common in the valley of the Susquehanna, between Williamsport and Wat- 

 sontown, a distance of some thirty miles, but they are abundant in some sections of the 

 State, while the only place that I know in Massachusetts, where they occur regularly, is 

 in the neighborhood of Lynn. I did, however, shoot a specimen in Newton, some years 

 ago. These birds frequent thickets, much after the manner of the Cat Bird, and breed about 

 the same time. They sing very sweetly,
