The Black-winged Stilt is a black-and-white wading bird with long pink legs, found in shallow wetlands across much of Africa and Eurasia. It is not a regular wild bird in the continental United States, where the similar Black-necked Stilt (Himantopus mexicanus) is the familiar species.
A mainland U.S. Black-necked Stilt usually has black across the back of the neck, while a Black-winged Stilt often has a whiter head and neck. Head markings vary, so check the range and several photos before deciding.
Why they get mixed upThey share the same long pink legs, straight bill, and black-and-white body plan.
