are in their usual health. Still, however, the effect might 
have been different, had the daily food of the bird been cockle 
burs, instead of Indian corn.

SETOPHAGA CANADENSIS. — Swainson.* 
Sylvia pardalina, Bonap. Synop. p. 79. 
This is a solitary, and, in the lower parts of Pennsylvania, 
rather a rare species ; being more numerous in the interior, 
particularly near the mountains, where the only two I ever 
met with were shot. They are silent birds, as far as I could 
observe ; and were busily darting among the branches after 
insects. From the specific name given them, it is probable 
that they are more plenty in Canada than in the United 
States ; where it is doubtful whether they be not mere pas- 
sengers in spring and autumn. 
* Mr Swainson, in a note to the Northern Zoology, has hinted his suspicion 
that this bird and Muscicapa Bonapartii of Audubon are the same : as far as 
we can judge from the two plates, there does not seem any resemblance. Mr 
Swainson adds, “ As regards the generic name, (of Setophaga Bonapartii,') we 
consider the whole structure of the bird as obviously intermediate between 
the Sylvicolce and the typical Setophaga, but more closely allied to the latter 
than the former.” For the present, we shall place the two following species 
in Setophaga, but suspect that this intermediate form will hereafter rank in 
the value of a sub-genus.* To this also maybe referred the Muscicapa Selbii 
of Audubon, which seems to approach nearer Setophaga in the more flattened 
representation of the bill, and stronger bristles. Mr Audubon has only met 
with it three times in Louisiana. The upper parts are of a dark olive colour ; 
the whole under parts, with a streak over each eye, rich yellow. The length 
is about five inches and a half ; it was very active in pursuit of flies, and the 
snapping of the bill, when seizing them, was distinctly heard at some distance.

* They are all furnished with rietorial bristles ; but the bill is not so much depressed. 
The habits are those of Setophaga.
