THIS member of the large family of warblers is considered rare, or only common in certain localities of its range, which is eastern United States in summer and Central America in winter. Its common names are blue golden-winged warbler, and golden-winged swamp warbler. It makes its appearance in May, when it may occasionally be seen about orchards. It soon retires into dense underbrush, however, and few persons who are not woodsmen ever get more than a glimpse of it. It breeds all through its range, but only casually north of Massachusetts. It builds its nest on or near the ground, in a plant tuft. It is made of grass, and is deep and bulky. The eggs are four or five, white, with reddish dots.

Ridgway says that June, 1885, he found these birds breeding along the southern edge of Calhoun Prairie, Richland county, Illinois, and Mr. H. K. Coale states that on May 11, 1884, in a wood on the Kankakee river, in Starke county, Indiana, he found the golden-winged warbler quite common. Eight were seen—all males, which were singing. Some were flushed from the ground and flew up to the nearest small tree, where they sat motionless next the trunk. The locality was a moist situation, overgrown with young trees and bushes.
