INSECTIVOROUS BIRDS. 
PROTHONOTARY WARBLER. 
{Sylvia protonotar ius, Lath. Wilson", iii. p. 72. pi. 24. fig. 3. Dacnis 
protonotarius , Audubon, pi. 3. Phil. Museum, No. 7020.) 
Sp. Charact. — Yellow; back and small wing-coverts yellow- 
olive * wings black ; rump and tail-coverts greyish-blue ; all the 
tail-feathers, except the 2 middle ones, with a spot of white on 
their inner vanes ; tail nearly even ; bill short. 
This beautiful species inhabits the Southern States 
commonly in summer, being plentiful in the low, dark, 
and swampy forests of the Mississippi near New Orleans, 
and in the wilds of Florida. In these solitary retreats 
they are seen nimbly flitting in search of insects, cater- 
pillars, and larvae, and every now and then utter a few 
creaking notes, scarcely deserving the name of song. 
They sometimes, though very rarely, proceed as far north 
as Pennsylvania. 
The usual length of this species is 5J inches ; alar stretch 8J. 
Inner vanes of the quills and tail black, edged with pale blue. Vent 
white. Bill black, rather long and robust. Legs and feet leaden- 
grey. Iris hazel. — In the female the yellow and blue are rather 
duller. 
BLUE-WINGED YELLOW WWRBLER. 
{Sylvia solitaria , Wilson, ii. p. 109. pi. 15. fig. 4. Dacnis solitaria , 
Audubon, pi. 20. Phil. Museum, No. 7307.) 
Sp. Charact. — - Olive-green ; forehead and all beneath yellow ; 
lores black ; wings with 2 whitish bands, and with the tail grey- 
ish-blue ; the 3 lateral tail-feathers with their inner vanes almost 
wholly white. 
About the beginning of May this species enters Penn- 
sylvania from the South, and frequents thickets and 
shrubberies in quest of the usual insect food of its tribe. 
At the approach of winter, very different from the Pine 
Warbler, with which it has sometimes been confounded, it 
retires to pass the winter in tropical America, having been
