SPECIES 35. SYLVM PARUS. 
HEMLOCK WARBLER. 
[Plate XLIV. — Fig. 3.] 
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 pe- 
culiarity 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; but possessing all the external char- 
acters 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 dis- 
tance; often begins at the lower branches, and hunts with great 
regularity and admirable dexterity, upwards to the top, then 
flies oflT to the next tree, at the lower branches of which it com- 
mences 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 plu- 
mage black, thinly streaked with yellow olive; head above yel- 
low, 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; prim- 
aries edged with olive, tertials with white; tail coverts black, 
tipt with olive; tail slightly forked, black, and edged with olive; 
the three exterior feathers altogether white on their inner vanes; 
legs and feet dirty yellow; eye dark hazel; a few bristles at the 
mouth; bill not notched. 
This was amale. Of the female I can at present give no account.
