Upper parts an olive brown, becoming darker on the head; under parts white, and also a white ring about the eye; two wing-bars a pale buff color, and the breast a light gray. They seem to prefer much the same localities for their nesting site as do the “Western.”

Nest.—Is usually built very low in willows or alders, bordering brooks or ponds, and is made of plant fibers, lined with the down, and sometimes horsehair; three or four creamy white eggs are marked with blotches of brown about the larger end (.70 × .54).
