410 INSECTIVOROUS BIRDS. 



PROTHONOTARY WARBLER. 



{Sylvia protonotarius, Lath. WiLsopf, iii. p. 72.pl. 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 larva3, and every now and then utter a few 

 creaking notes, scarcely deserving the name of song. 

 They sometimes, though very rarely, pjbceed as far north 

 as Pennsylvania. 



The usual length of this species is 5^ inches ; alar stretch 8^. 

 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.

{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
