Depending
on the source, the Black-winged Stilt may be a separate species from North
America's Black-necked Stilt, or most stilt populations are simply different
races of the same species. For those groups that consider all stilts
to be one species, the usual name is this one, the Black-winged Stilt.
Plumage is distinct from the Black-necked Stilt, and Black-winged Stilts are
only extremely rare visitors to North America. The first bird was
found on Nizki Island in the far western Aleutian Islands in 1983. Another
single bird was found on St. George Island in 2003.
Habitat: Found in a variety of shallow-water
habitats, from wetlands, ponds and lakes, flooded farm fields, and coastal
areas.
Diet: Feeds heavily on aquatic insects, but will
also take small crustaceans, mollusks, or other small invertebrates.
Behavior: Forages by wading in shallow water,
grabbing food items near the surface with their bill. They may also
occasionally dip their head below the water in search of prey further below
the water's surface.
Nesting: The nest is variable, and can be a
shallow scrape on the ground with a sparse lining of grasses or other
materials, a more substantial nest of sticks, mud, shells, or other
materials, or a floating mass of grasses, reeds, and other vegetation.
The nest is placed near a water source. The female usually lays 3 or 4 eggs,
and both parents help to incubate them. The young are fully capable of
wading, walking, and swimming within 24 hours after hatching
Migration: Migratory status depends upon the local
population. Many Black-winged Stilts found in warmer climates are
full-time residents. Others that breed in more temperate or colder areas are
strongly migratory, moving to lower latitudes or towards the coast for the
winter months.
Conservation Status: Populations are strong and
generally stable. Particularly for those groups who classify all
stilts as one species, they are found over an extremely large geographic
range and are unlikely to face threats to their overall global population.
The IUCN lists the
Black-winged Stilt as a species of "Least Concern".
