The diet of the black-winged stilt is variable according to season, but typically comprises aquatic insects, molluscs, crustaceans, spiders, worms, tadpoles, small fish, fish eggs and seeds (3). With its long legs, it can wade into deeper water, where it may be seen snatching insects that hover over the water’s surface, dipping its head below the water to catch small fish, or pulling small worms from the mud (5).
Black-winged stilts residing in northern regions migrate over long distances to reach their southern wintering grounds (3). Although it will often breed in solitude, the black-winged stilt is a typically social bird and can be found in groups of up to a thousand during the winter migration (3).
During breeding, parental investment is high from both male and female birds, with males devoting a significant amount of time to nest building and egg incubation (6). This parental team appears to be monogamous, as while the male stays behind to tend the nest, the foraging female remains faithful (6). The nest is either a depression in hard ground or arranged on a floating mass of vegetation, preferably situated with all-round visibility (3).
