380 INSECTIVOROUS BIRDS. 



ORANGE-THROATED WARBLER. 



(^Sylvia auricoUis, Latham, iv. p. 481. No. 103. Pennant, Arct, 



Zool. No. 304.) 



Sp. Charact. — Olive-green; rump and tail-coverts cinereous ; pri- 

 maries brown ; throat and under side of the body, orange ; vent 

 white. — Female with the colors paler. 



This is another rare and transient species, which pro- 

 ceeds from its winter-quarters in Mexico and the South- 

 ern States as far as Canada, in summer, to breed. About 

 the 23d of March, I saw numbers of these birds in the 

 lower parts of Georgia, feeding partly on berries, and on 

 insects, in the pursuit of which they were busily engag- 

 ed. I have, very rarely, seen an individual in this part of 

 Massachusetts towards the close of spring ; and it ap- 

 pears that Brisson received it from Canada. 



Above olive-green, except the lower part of the back, rump, and 

 greater wing-coverts, which are cinereous ; primaries brown, edged 

 with dark ash, on the inner webs with dirty white. Beneath 

 orange, except the vent, which is white. 



CHESNUT-SIDED WARBLER. 



^Sylvia icterocephala, Lath. Audubon, pi. 59. Orn. Biog. i. p. 306. 

 S. pennsylvanica, Wilson, ii. p. 99. pi. 14. fig. 5. Phil. Museum, 

 No. 7006.) 



Sp. Charact. — Crown yellow; under side of the body white 3 

 sides from the throat chesnut ; wings with 2 pale yellow bands ; 

 the 3 lateral tail-feathers marked with white. — Female with the 

 crown and chesnut sides paler. 



This rare and beautiful Sylvia, which probably win- 

 ters in tropical America, appears in the Middle and 

 Northern States early in May on its way north to breed ; 

 they are also seen in the spring in Canada and around 

 Hudson's Bay. A few remain, no doubt, to rear their 

 young in secluded mountainous situations, in the North-
