BLACK-THROATED BLUE WARBLER.

a week or ten days, viz. from the 25th 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 lucrative ; 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 colour above; the throat, 
cheeks, front and upper part of the breast, are 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 more of a 
dusky ash on the breast; and, in some specimens, nearly 
white. 
They, no doubt, pass this way on their return in autumn, 
for I have myself shot several in that season ; but as the 
woods are then still thick with leaves, they are much more 
difficult to be seen, and make a shorter stay than they do in 
spring.
