CANADA FLYCATCHER. 253 
death of a tame Carolina Paroquet,to ascertain the fact of the poison- 
ous effects of their head and intestines on cats. Having shut up a cat 
and her two kittens, the latter only a few days old, in a room with the 
head, neck, and whole intestines of the Paroquet, I found, on the next 
morning, the whole eaten, except a small part of the bill. The cat 
exhibited no symptom of sickness; and, at this moment, three days 
after the experiment has been made, she and her kittens 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.

Tuis 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 passen- 
gers in spring and autumn. 
This species is four inches and a half long, and eight in extent; 
front, black ; crown, dappled with small streaks of gray and spots of 
black ; line from the nostril to,and around the eye, yellow ; below the 
eye, a streak or spot of black, descending along the sidesof the throat, 
which, as well as the breast and belly, is brilliant yellow, the breast 
* 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 nume (of Setophaga Bonapartii,) we consider the 
whole structure of the bird as obviously Sieonedinte herrea the Sylvicolce and 
the typical Setophagce, but more closely allied to the Jatter than the former.” - For 
ahe present, we shall place the two following species in Setophaga, but suspect that 
this intermediate form will’ hereafter rank in the value of a su -genus.* To this, 
also, may be referred the Muscicapa Selbii of Audubon, which seems to approach 
- nearer Setophaga in the more flattened representation of the bill and stronger bris- 
tles. Mr. Audubon-has only met with it three times in Louisiana. The upper parts 
are of a dark olive color; the whole under parts, with a streak over-each eye, rich 
yellow. The length is about five inches abd ahalf. It was very active in pursuit 
of flies, and the snapping of the bill, when seizing them, was distinctly heard at 
some distance. — ED. 
* They are all furnished with rictorial bristles, but tae bill is not so much depressed. 
The habits are those 3S Setophaga. i
