22-12-2023 PIRANG PONDS, GAMBIA - BLACK WINGED STILT (Himantopus himantopus)

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 was formerly applied to a single, almost cosmopolitan species. It is now normally applied to the form that is widespread in Eurosiberia and Africa and which was formerly regarded as the nominate subspecies of Himantopus himantopus sensu lato. The scientific name Himantopus comes from the Greek meaning "strap foot" or "thong foot". Most sources today accept 2–4 species. It is sometimes called pied stilt, but that name is now reserved for the Australian species, Himantopus leucocephalus.


Adults are 33–36 cm (13–14 in) long. They have long pink legs, a long thin black bill and are blackish above and white below, with a white head and neck with a varying amount of black. Males have a black back, often with greenish gloss. Females' backs have a brown hue, contrasting with the black remiges. In the populations that have the top of the head normally white at least in winter, females tend to have less black on head and neck all year round, while males often have much black, particularly in summer. This difference is not clear-cut, however, and males usually get all-white heads in winter.

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

22-11-2023 EL FONDO, ALICANTE - BLACK WINGED STILT (Himantopus himantopus)

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. The taxonomic name Himantopus comes from Greek, meaning "strap-foot" or "thong-foot".

Adults are 33–36 cm (13–14 in) long, with long, pink legs, and a long, rather thin black bill. The birds are generally black above and white below, with a white head and neck (with a varying amount of black, species-dependent). Males have a black back, often with a greenish gloss or sheen. Females' backs have a brownish hue, contrasting with the black remiges. In populations where the top of the head is normally white (at least in winter), females tend to have less black on the head and neck the entire year-round, while males often have much more black, particularly in summer. This difference is not clear-cut, however, and males usually grow all-white head feathers in winter.[citation needed]

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.


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, and after a 27-year hiatus there were two instances of successful breeding in Southern England in 2014. 13 young were fledged in southern England in 2017.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.

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 scientific name H. himantopus is sometimes applied to a single, almost cosmopolitan species.
