BLACK-THROATED BLUE WARBLER. 
The Blue-eyed Warbler is five inches long and seven broad ; hind 
head and back greenish yellow ; crown, front and whole lower parts rich 
golden yellow ; breast and sides streaked laterally with dark red ; wings 
and tail deep brown, except the edges of the former and the inner vanes 
of the latter, which are yellow ; the tail is also slightly forked ; legs a 
pale clay color; bill and eyelids light blue. The female is of a less 
brilliant yellow, and the streaks of red. on the breast are fewer and more 
obscure. Buffon is mistaken in supposing No. 1, of PI. Enl. Plate lviii., 
to be the female of this species.

I KNOW little of this bird. It is one of those transient visitors that 
in the month of April pass through Pennsylvania on its way to the north 
to breed. It has much of the Flycatcher in its manners, though the 
form of its bill is decisively that of the Warbler. These birds are occa- 
sionally seen for about a week or ten days, viz., from the twenty-fifth of 
April to the end of the first week in May. I sought for them in the 
Southern States, in winter, but in vain. It is highly probable that they 
breed in Canada ; but the summer residents among the feathered race, 
on that part of the continent, are little known, or attended to. The 
habits of the bear, the deer and beaver, are much more interesting: to 
those people, and for a good substantial reason too, because more lucra- 
tive ; and unless there should arrive an order from England for a cargo 
of skins of Warblers and Flycatchers, sufficient to make them an object 
worth speculation, we are likely to know as little of them hereafter as at 
present. 
This species is five inches long, and seven and a half broad, and is 
wholly of a fine light slate color above ; the throat, cheeks, front 
and upper part of the breast is black ; wings and tail dusky black, 
the primaries marked with a spot of white immediately below their 
coverts ; tail edged with blue ; belly and vent white ; legs and feet dirty 
yellow ; bill black, and beset with bristles at the base. The female is
