INSECTIVOROUS BIRDS. 
a good deal similar, in common with the Worm-eating 
Warbler. I have never yet seen it in Massachusetts, and 
if it really does proceed north to breed, it must follow a 
western route. 
The length of this species is from 4j to 5 inches, and 7 in alar 
extent. The 3 lateral tail-feathers with a spot of white on their in- 
ner vanes. Tail a little forked. The black band through the eye 
separated from the yellow crown by a line of white. Bill black. 
Legs dark ash. Iris hazel. 
TENNESSEE WARBLER. 
(Sylvia per egrina, Wilson, iii. p.83. pi. 25. fig. 2. S. bicolor ?V ieill. 
Phil? Museum. No. 7787.) 
Sp. Charact. — Yellow-olive, bluish on the head; line over the 
eye pale yellow ; beneath whitish ; wings without bands ; bill 
very short. 
This rare and plain species was discovered by Wilson 
on the banks of Cumberland river in the state of Ten- 
nessee. It was hunting with great agility among the 
opening leaves in spring, and like the rest of the section 
to which it appertains, possesses a good deal of the hab- 
its of the Titmouse. Its notes were few and weak, and 
its food, as usual, smooth caterpillars and winged insects. 
This species is 4| inches long ; and 8 in alar extent. Wings dusky, 
edged with olive. Tail forked, olive, relieved with dusky. Throat 
and breast pale cream-color ; belly and vent white. Legs purplish- 
brown. Bill dark dusky, somewhat paler below. Iris hazel. — In 
the female the colors are more obscure.
