The black-winged stilt (Himantopus himantopus) is a widely distributed very long-legged wader in the avocet and stilt family (Recurvirostridae). The scientific name H. himantopus is sometimes applied to a single, almost cosmopolitan species. Alternatively, it is restricted to the form that is widespread in Europe, Asia and Africa, which equals the nominate group of Himantopus himantopus sensu lato (whereas the black-necked, H. mexicanus, and white-backed stilt, H. melanurus, both inhabit the Americas, and the pied stilt, H. leucocephalus, inhabit southeast Asia to Australia and New Zealand). Most sources today accept 1–4 species. The scientific name Himantopus comes from the Greek meaning “strap foot” or “thong foot”.
