The adults of this handsome species may readily be known by the white underparts and the broad chestnut stripe on the flanks; the crown is yellow. They frequent low brush in open woods or on hillsides and pastures, nesting at low elevations, usually below three feet from the ground, and often concealing their nests beneath the leaves in the tops of low small bushes. The nests are made of grasses, weed stems and some fibres, but they do not have as wooly an appearance as those of the Yellow Warblers which nest in the same localities and similar locations. Their eggs are white or creamy white (never greenish white), specked with brown and gray. Size .65 x .50. Data. - Worcester, Mass., June 6, 1890. Nest in the top of a huckleberry bush, 2 feet from the ground; made of grasses and plant fibres. Bird did not leave nest until touched with the hand.
