oval in form, creamy-white in color, spotted and blotched with reddish-brown. Dimensions from ^x'SB to '4Sx'6u. 
HABITS. 
The only time that I ever met with the beautiful, little Blue Warbler was at* Williams¬ 
port, Pennsylvania, about the tenth of May. There was a large migration of Warblers 
passing at the time, and this species was among them, but was rather rare. In general 
habits, this bird resembled other Warblers, and I was not fortunate enough to hear the 
song. 
DENDRCECA BLACKBURNI2E 
Blackburnian Warbler. 
Dendrceca Blackburnice Bd., Birds N. A.; 1858, 274. 
Sp. Cii. Eorm, slender. Size, large. Color. Adult male. Above, sides of head and neck, and streaks on sides, 
black. Outer edge of secondaries, large patch on wings and one on inner webs of three outer tail feathers, white. Spot 
on crown, superciliary stripe, patch on neck, throat, and upper breast, bright orange, becoming creamy on remainder of 
lower surface. Iris, bill, and feet, brown. Female, similar but duller, and the white patch on wings is divided into two 
bands. Young, like adult female but very much paler, the yellow on the breast and streakings above in young females 
being nearly obsolete. 
Observations. Known by the dark colors above, orange throat and superciliary line, which are discernible in all stag¬ 
es. Occurs in summer from Maine, northward; wintering south of our limits. Dimensions. Length, 5 25; stretch, 8 20; 
wing, 2 - 65; tail, 1*85; bill, ’75; tarsus, -38. 
HABITS. 
I shot a female Blackburnian Warbler at Williamsport, Pennsylvania, that exhibited 
unmistakable evidences of having recently deposited her eggs, and afterward saw several 
other specimens there, so I have no doubt but what these Warblers breed in that section, 
though as a rule, they nest much further north, in the evergreen woods of Maine, where they 
are very abundant. The Blackburnians are rare in Eastern Massachusetts during migra¬ 
tions, but are remarkably abundant in the valley of the Susquehanna at this time, insomuch 
so, that I have counted upward of twenty in sight at once. I have never met with the nest 
and eggs of this species, but am confident that it breeds in high evergreen trees. 
DENDRCECA CASTANEA. 
Bay-breasted Warbler. 
Dendrceca castanea Bd., Birds N. A.; 1858, 276. 
Sp. Ch. Form, slender. Size, medium. Color. Adult. Sides of head and upper parts, sooty black with the feath¬ 
ers of all but head, edged with greenish-ash. Two bands on wings and patch on inner webs of three outer tail feathers, 
white; back part of crown, throat, and sides, dark-chestnut; patch on side of neck and under tail coverts, buff; remainder 
of under parts, creamy; iris and bill, brown; feet, bluish. Female, similar to male but the chestnut is not as extended and 
the top of the head is greenish. In autumn, and Young. Above, where there are streakings of dusky, and sides of head 
and neck, greenish becoming bufiy-yellow below; there is often only a trace of chestnut on flanks, and this occasionally 
is absent in young females. 
Observations. Known by the chestnut markings; also see observations on page 30. Occurs in summer from Maine, 
northward; winters south of our limits. Dimensions. Length,5 55; stretch, 8‘75; wing, 2‘85; tail, 2'05; bill, ’73;tarsus, '40.
