- H. h. knudseni
- H. h. mexicanus
- H. h. melanurus
The Black-winged Stilt,
Himantopus himantopus, is a large wader in the avocet and stilt family,
Recurvirostridae.
Adults are 33-36 cm long. They
have long pink legs, a long thin black bill and are mainly white with a dark
cap and a dark back.
The taxonomy of this bird
is still somewhat contentious: some sources believe that there are as many as
five distinct species; others consider some or all of these to be subspecies. The
five forms are:
- nominate Himantopus himantopus
himantopus, which occurs in most of the warmer parts of southern and
southeastern Europe, southern Asia and north Africa.
- the Black-necked Stilt, which breeds from
the US to northern South American has a dark head with a white spot over
the eye. It is recorded as Himantopus mexicanus in the Sibley-Monroe
checklist.
- the southern South America melanurus
is larger than mexicanus and often has a white crown.
- the rare and endangered Hawaiian knudseni
has more extensive black on its neck than the American forms.
- leucocephalus of southeastern Indonesia and Australia
has a white head.
The breeding habitat of all
forms is marshes, shallow lakes and ponds. The nest site is a bare spot on the
ground near water. These birds often nest in small groups, sometimes with avocets.
The
Black-necked Stilt.
Some populations are migratory
and move to the ocean coasts in winter.
These birds pick up their
food from sand or water. They mainly eat insects and crustaceans.
Threats
and conservation
The Hawaiian Stilt
or ae`o is endangered due to habitat loss. It is the only shorebird to
breed in the Hawaiian Islands.
The Black-winged Stilt is
one of the species to which the Agreement on the Conservation of
African-Eurasian Migratory Waterbirds (AEWA) applies.
