A dull-colored little Warbler which we know as a rather rare migrant, associated with the traveling companies of its family on their northward and southward journeys. The song is described by Mrs. Farwell as noticeable but not musical and resembling that of the Chipping Sparrow.
NORTHERN PARULA WARBLER
Compsothlypis americana usneæ. [Case 7], Fig. 39
A small, bluish Warbler with a yellow patch on the back, a dark band on the breast, and white wing-bars. L. 4¾.
Range. Nests from Virginia and Louisiana to Canada; winters in the tropics.
Washington, T.V., but dates not distinguishable from those of americana. Ossining, common T.V., May 2-28; Sept. 21-Oct. 7. Cambridge, common T.V., May 1-28; Sept. 10-30. N. Ohio, not common T.V., May 1-18. Glen Ellyn, not common T.V., May 3-28; Aug. 25-Oct. 1. SE. Minn., common T. V., May 5-Sept. 9.
A common migrant, traveling with other Wood Warblers, but in summer usually restricted to swampy localities where usnea moss flourishes. Of, or rather in this, it makes its nest, laying 4-5 white, brown-marked eggs the latter half of May. To describe its song as several wheezy notes running into a little trill, conveys no idea of pleasing character. It is easily recognized and, in time, acquires associations with what, to bird-lovers, is the most delightful season of the year.
