This is another scarce species in Pennsylvania, making its appear- 
ance here about the beginning of May ; and again in September on its 
return, but is seldom seen here during the middle of summer. It is an 
active silent bird. Inhabits also the state of New York, from whence 
it was first sent to Europe. Latham has numbered this as a variety of 
the Yellow-fronted Warbler, a very different species. The specimen 
sent to Europe, and first described by Pennant, appears also to have 
been a female, as the breast is said to be yclloio, instead of the brilliant 
orange with which it is ornamented. Of the nest and habits of this 
bird I can give no account, as there is not more than one or two of 
these birds to be found here in a season, even with the most diligent 
search. 
The Blackburnian Warbler is four inches and a half long, and seven 
in extent ; crown black, divided by a line of orange ; the black again 
bounded on the outside by a stripe of rich orange passing over the eye ; 
under the eye a small touch of orange yellow ; whole throat and breast 
rich fiery orange, bounded by spots and streaks of black ; belly dull 
yellow, also streaked Avitk black ; vent white ; back black, skirted with 
ash ; wings the same, marked with a large lateral spot of white ; tail 
slightly forked ; the interior vanes of the three exterior feathers white ; 
cheeks black ; bill and legs brown. The female is yellow where the 
male is orange ; the black streaks are also more obscure and less 
numerous.
