These little fly-catching Warblers are abundant in the United States during migrations, being found in woods or swamps, and very often in apple trees when they are in bloom. They fly about among the outer branches snatching insects from the foliage or blossoms, and often dashing out to catch one that is flying by. Their natural quickness is intensified by their very attractive plumage which harmonizes perfectly with green leaves.
Song.—A simple and rather weak trill.
Nest.—Of leaves and bark, imbedded in the ground under bushes on the edges of swamps or woods; eggs white, specked with reddish brown (.60 × 48).
Range.—Eastern N. A., breeding from the northern edge of the U. S. northward; winters in Central America. Two subspecies are found west of the Rockies.
CANADIAN WARBLER
686. Wilsonia canadensis. 5½ inches
Male, with a necklace of black spots, white eye ring and lores; female, and young, with only a slight indication of the necklace.
These Warblers travel northward in company with many other kinds, always keeping in the underbrush near the ground, except when they come out into orchards and parks. Like the two last, they are very lively, rarely remaining still for more than a few seconds, before they must dash after some tempting morsel that is flying by.
Song.—A loud liquid warble, most nearly resembling that of the Water-Thrush; call, a sharp, querulous chip.
