ish-green, tinged with ash on crown and sides of head. Yellow beneath, with throat and upper breast, ashy, becoming 
darker posteriorly. Ring around eye, white. Female, and Young , similar but much duller throughout. 
Observations. Known by the square tail, white ring around eye, and ashy throat. Occurs in summer from Maine, 
northward, wintering south of our limits. Dimensions. Length, 5-25; stretch, 9’OG; wing, 3*00; tail, 2'28; bill, ‘46; tar¬ 
sus, ’80. 
HABITS. 
The migrations of the 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 has 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. 
OPORORNIS FORMOSTJS. 
Kentucky Warbler. 
Oporornis formosus Bd., Birds N. A.; 1858, 247. 
Sp. Cii. Form, slender. Size, small. Color. Adult male. Above and on sides, yellowish-green. Crown and sides 
of head and patch on side of neck, black with feathers on top of head narrowly tipped with dark ash. Superciliary line 
and under parts, bright yellow. Female , similar but duller, and with less black on head. 
Observations. Known by the black crown and yellow under parts. Breeds from New York, westward and south¬ 
ward; wintering south of our limits. Dimensions. Length, 5*36; stretch, 8'85; wing, 2 - 85; tail, 2'20; bill, *43; tarsus, ’82. 
Nests and Eggs. Nests, placed on grass stalks, composed of fine grass, rootlets, strips of bark, etc. Eggs, four to six 
in number, oval in form, white in color, dotted with reddish-brown. Dimensions from *50 x *70 to '55 x ‘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 habits. 
ICTERIA VIRIDIS. 
YeHow-breasted Chat. 
Icterid viridis Bon., Obs. Wils.; 1826. 
Sp. Ch. Form, slender. Size, large. Bill, slightly curved. Color. Adult male. Above, ashy-green; beneath to 
middle of breast, light-yellow; ring around eye and line from it to bill, and remainder of under parts, white. Spot in front

of our limits. Dimensions. Length, 6'75; stretch, 9*75; wing, 2*93; tail, 3*16; bill, - 58; tarsus, l'OO. 
Nests and Eggs. Nests, placed in hushes and composed of grass, grape-vine bark, weeds, etc. Eggs, three or four in 
number, elliptical in form, white in color, spotted and blotched with reddish-brown and lilac. Dimensions from *60 x *80 
to *67 x 95. 
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,
