The black-winged stilt (Himantopus himantopus) is a widely distributed, very long-legged wader in the avocet and stilt family Recurvirostridae. Its scientific name, Himantopus himantopus, is sometimes used to generalize 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 H. himantopus sensu lato. Meanwhile, the black-necked (H. mexicanus) and white-backed stilts (H. melanurus) both inhabit the Americas; the pied stilt (H. leucocephalus) ranges from Australia and New Zealand. Today, most sources accept between one and four actual species.
The black-winged stilt was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. He placed it with the plovers in the genus Charadrius and coined the binomial name Charadrius himantopus. He specified the type locality as southern Europe. The taxonomic name Himantopus comes from Greek, meaning "strap-foot" or "thong-foot". The black-winged stilt is now one of five species placed in the genus Himantopus that was introduced by the French naturalist Mathurin Jacques Brisson... Wikipedia →
