BLUE-WINGED YELLOW WARBLER. 
181 
The first specimen of this bird taken notice of by European writers 
was transmitted, with many others, by Mr. William Bartram to Mr. 
Edwards, by whom it was drawn and etched in the 277th plate of his 
Ornithology. In his remarks on this bird he seems at a loss to determine 
whether it is not the Pine Creeper of Catesby ;* a difficulty occasioned 
by the very imperfect coloring and figure of Catesby's bird. The Pine 
Creeper, however, is a much larger bird, is of a dark yellow olive above, 
and orange yellow below ; has all the habits of a Creeper, alighting on 
the trunks of the pine trees, running nimbly round them, and, according 
to Mr. Abbot, builds a pensile nest. I observed thousands of them in 
the pine woods of Carolina and Georgia, where they are resident, but 
have never met with them in any part of Pennsylvania. 
This species is five inches and a half long, and seven and a half 
broad; hind head and whole back a rich green olive; crown and front 
orange yellow ; whole lower parts yellow, except the vent feathers, 
which are white ; bill black above, lighter below : lores black ; the form 
of the bill approximates a little to that of the Finch; wings and tail 
deep brown, broadly edged with pale slate, which makes them appear 
wholly of that tint, except at the tips ; first and second row of coverts 
tipped with white, slightly stained with yellow ; the three exterior tail 
feathers have their inner vanes nearly all white ; legs pale bluish ; feet 
dirty yellow ; the two middle tail feathers are pale slate. The female 
differs very little in color from the male. 
This species very much resembles the Prothonotary Warbler of 
Pennant and Buffon ; the only difference I can perceive on comparing 
specimens of each, is that the yellow of the Prothonotary is more of an 
orange tint, and the bird somewhat larger.
