Black-winged stilts show a courtship with preening and bill-dipping. When the female assumes a receptive posture, the mail moves a few times from side to side behind the femal before mating begins.
The female is duller on the wings than the male.
The nest site of black-winged stilts is a bare spot on the ground near water. The nest is built from bedris, driftwood, grass and other vegetation. These birds often nest in small groups, sometimes with avocets.
