It is also found occupying saline mudflats and estuaries, but rarely. They are generally sedentary, with a single bird, a pair, or a family group occupying a stretch of habitat on a more or less permanent basis. However, some individuals appear to travel considerable distances, and flocks will sometimes congregate in food-rich areas. Unlike many other wading birds, black-fronted dotterels retain the same plumage all year round, which makes identification easier. They forage in a series of short running motions, holding the body horizontal, stopping to peck from time to time with a rapid bobbing motion. Their diet consists of mostly insects and other small creatures, supplemented by a few seeds. Eggs gestation period: 4–5 weeks. up to 3 eggs have been observe on nest. 24 hours after they hatch chicks leave the nest to hide in less exposed areas, at the same time both parents look after them.
