The Black-winged Stilt (Himantopus himantopus) is a large black and white wader with long orange-red legs and a straight black bill. It has black on the back of the neck, a white collar and a red iris. Both sexes are similar, and the plumage does not change during the year. Black-winged Stilts give a repeated high-pitched barking call. Young Black-winged Stilts lack black on the back of the neck and have grey-brown wings and back, speckled with white.
