This pretty warbler is a common summer resident of Vermont, beino 
among the first of the warblers to reach us in the spring, although the 
wmter is spent in Central America. Searching carefully the evergreen 
trees and singing while he works, this bird does much good in ridding 
the trees of injurious insects. Mrs. Wright hears the black-throated 
green warbler say when singing: "Will you co-ome, will you co-ome. 
will you?" with an emphatic pause on the last two syllables.
