Statewide as a rare migrant. Department of Conservation. Description:The Black-winged Stilt has a mostly white body with areas of black on the wings and the back of the head. Conservation The Hawaiian population is endangered due to habitat loss and probably also introduced predators. This makes their nests vulnerable because predators can reach the nests overland or through shallow water. A clutch comprises 2–5 eggs, which hatch in 24–29 days. The pair take it in turns to incubate the four eggs, and care for the chicks (2). The black plumage of these birds may be an adaptation to "absorb heat better in the cold, windswept habitat of glacial riverbeds and lakeshores". According to the Wikipedia resource the current wild population is estimated at 169 wild adult birds (as of May 2020). The nest is a small depression made with twigs, grass, and waterweeds lined with vegetation. Black-necked Stilt populations have been stable between 1966 and 2015 in continental North America, according to the North American Breeding Bird Survey. The population may have numbered 500–1000 birds in the 1940s, but began to rapidly decline in the 1950s, and just 68 adults were counted in 1962. The female lays 3 to 5 eggs from September to December, peaking in October and both parents incubate them for roughly 25 days. Black stilts are also vulnerable to the loss of their native habitat. Intensive management began in 1981, when numbers had declined to just 23 adult birds. The black-necked stilt is one of Missouri’s easy to identify shorebirds, for its very long, salmon-pink legs and strikingly contrasted black and white plumage. It is boldly marked with black and white above (not just black) and white below; the head and neck are rusty during breeding season and gray during nonbreeding season; the legs are grayish (not pink or red); and the bill is upturned (strongly upturned in the female, slightly upturned in the male). The total population is now more healthy than it once was but the bird remains critically endangered due to introduced predators. Partners in Flight estimates the global breeding population at 900,000 birds, with a Continental Concern Score of 8 out of 20, indicating it is a species of low conservation concern. They inhabit braided rivers and nearby wetlands such as swamps, ponds, and lake deltas; some birds can also occur along the coastline. The black bill is slim and straight. At times they have been considered separate species.

In summer, it breeds locally in the Bootheel. Predation from mammalian invasive species poses the greatest threat to the survival of the species. Because Black stilts nest on braided river beds, they are also threatened by changes in river flows as a result of new and existing hydroelectric dams. Choosing some area raised higher than the water level, they scrape a depression into the ground and usually line it with nearby materials such as grass, rocks, and other objects. Most Missourians see black-necked stilts during migration, as they forage on mudflats, shorelines, and shallow wastewater lagoons. 23/05/2020.

The anti-predator display called 'the popcorn display' consists of a group of adults circling around a ground predator and hopping side to side while flapping their wings. Conservation programme. However, the Australasian black-winged/black stilt split is an estimate based off percentage sequence divergence (i.e., 5% partial D-loop/control region equating to a divergence time of ca. One black-winged stilt chick came out of the egg early this morning at RSPB Cliffe Pools on the north Kent Marshes and second and third chicks hatched mid morning at RSPB Medmerry near Chichester, The other eggs in both broods are expected to hatch later today. Similar to the Killdeer, the Black –necked Stilt, due to its ground nesting, may attempt to attract nest predators by having a group of adults fly away from the nesting site and perform a distraction display in hope of drawing the predator away from the nest.

The displays include one in which nonincubating birds fly up to mob predators, and one in which all birds encircle a predator, hop up and down, and flap their wings.” A more general note on shorebirds from ASDM: Like most other shorebirds, black-necked stilts are ground nesters. Their diet includes mainly insects but they will also consume mollusks, crustaceans, aquatic worms, and small fish. The elaborate defensive strategies — ranging from raucous swirling mayhem, to distraction displays, to outright harassment of intruders — remind us how vulnerable the eggs, young, and overworked, nesting parents are to predation.
