184 BLACK-TIIROATED 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 Iviii., 

 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 tho 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 

 whoUj'- of a fine light slate color above; the throat, cheeks, from 

 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
