WORM-EATING WARBLER. 
(i Sylvia vermivora , Lath. Wilson, iii. p. 74. pi. 24. fig. 4. Dacnis 
vermivora , Audubok, pi. 34. Phil. Museum, No. 6848.) 
Sp. Charact. — Dusky-olive; head striped with black and buff; 
beneath dull buff, brighter on the breast ; bill stout. 
This species arrives in Pennsylvania about the middle 
of May, and migrates to the South towards the close of 
September ; they were seen feeding their young, in that 
state, about the 25th of June, by Wilson, so that some pairs 
stay and breed there. They are very active and inde- 
fatigable insect-hunters, and have much of the manners 
and even the note of the Marsh Titmouse or Chicadee. 
About the 4th of October, I have seen a pair of these 
birds roving through the branches of trees with restless 
agility, hanging on the twigs and examining the trunks, 
in quest, probably, of spiders and other lurking and dor- 
mant insects and their larvae. One of them likewise 
kept up a constant complaining call, like the sound of 
tshe de de . 
Length 5^ inches,, and 8 inches in alar extent. Above dark olive, 
except the quills and tail, which are umber-brown. Tail scarcely fork- 
ed. Head buff, marked with 4 longitudinal stripes of umber-brown. 
Breast orange-buff, mixed with dusky. Vent waved with dusky 
olive. Bill blackish above, below flesh-colored. Legs pale flesh- 
color. Iris hazel. — Female nearly similar to the male.
