117 . SYLVIA PARUS , WILSON. HEMLOCK WARBLER. 
WILSON, PLATE XLIV. FIG. III. — MALE. 
This is another nondescript, first met with in the 
Great Pine swamp, Pennsylvania. From observing it 
almost always among the branches of the hemlock 
trees, I have designated it by that appellation, the 
markings of its plumage not affording me a peculiarity 
sufficient for a specific name. It is a most lively and 
active little bird, climbing among the twigs, and hanging 
like a titmouse on the branches; hut possessing all the 
external characters of the warblers. It has a few low 
and very sweet notes, at which times it stops and 
repeats them for a short time, then darts about as 
before. It shoots after flies to a considerable distance ; 
often begins at the lower branches, and hunts with 
great regularity and admirable dexterity, upwards to 
the top, then flies off to the next tree, at the lower 
branches of which it commences hunting upwards as 
before. 
This species is five inches and a half long; and 
eight inches in extent ; bill, black above, pale below , 
upper parts of the plumage, black, thinly streaked with 
yellow olive ; head above, yellow, dotted with black ; 
line from the nostril over the eye, sides of the neck, 
and whole breast, rich yellow; belly, paler, streaked 
with dusky ; round the breast, some small streaks of 
blackish ; wing, black, the greater coverts and next 
superior row, broadly tipt with white, forming two broad 
bars across the wing ; primaries, edged with olive, 
tertials, with white ; tail-coverts, black, tipt with olive ;
