INSECTIVOROUS BIRDS. 
ORANGE-THROATED WARBLER. 
( Sylvia auricollis , 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; 
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-
