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 Australasia and New Zealand. Today, most sources accept between one and four actual species.[1][2][3][4] The taxonomic name Himantopus comes from Greek, meaning "strap-foot" or "thong-foot".[5]

Description

Immature birds are grey, instead of black, and have a markedly sandy hue on their wings, with light feather fringes appearing as a whitish line in flight.

Taxonomy and systematics

The taxonomy of this bird is still somewhat contentious; it is one of four distinct species, which sometimes are considered subspecies of H. himantopus. H. himantopus sensu lato is made up of a single species, with 5–7 subspecies, and is sometimes referred to as the common stilt. The name “black-winged stilt” refers to H. himantopus sensu stricto, with two subspecies (H.h. himantopus from the Palearctic to South Asia, and H.h. meridionalis from the Afrotropical region).[6]

Ecology and status

The breeding habitat of all these stilts is marshes, shallow lakes and ponds. Some populations are migratory and move to the ocean coasts in winter; those in warmer regions are generally resident or short-range vagrants. In Europe, the black-winged stilt is a regular spring overshoot vagrant north of its normal range, occasionally remaining to breed in northern European countries. Pairs successfully bred in Britain in 1987,[7] and after a 27-year hiatus there were two instances of successful breeding in Southern England in 2014.[8] 13 young were fledged in southern England in 2017.[9] Four chicks were successfully fledged in northern England in 2022; this is believed to be the most northerly breeding success for the black-winged stilt.[10][11]

These birds pick up their food from sand or water. They eat mainly insects and crustaceans.

The nest site is a bare spot on the ground near water. These birds often nest in small groups, sometimes with avocets.

The black-winged stilt is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds applies.
