The New International Encyclopædia/Maryland Yellowthroat
MARYLAND YELLOWTHROAT. A North American warbler (Geothlypis trichas), common in summer throughout the continent. It is about 5½ inches long, olive-green above and bright yellow below, with a conspicuous broad black band or ‘mask’ across the forehead (of the male), which includes the bill, extends back to a point on each side of the neck, and is bordered above by a white line; the female has only a dull white line above the eye. These warblers spend their time near the ground and make their nests there, usually beside a stream; and they utter a short, questioning song as characteristic as it is pretty. Several closely allied species, as the Kentucky warbler (q.v.), mourning, Connecticut, and McGillivray's warblers, belong to this genus, and visit the United States, while several others are found only in Mexico and Central America.
