These birds probe with their bill in mud or shallow water, also picking up food by sight. They mainly eat insects, crabs and other small aquatic animals.
Rove beetle
Rove beetles are known from every type of habitat in which beetles occur, and their diets include just about everything except the living tissues of higher plants, but now including higher plants with the discovery of the diet of "Himalusa thailandensis". Most rove beetles are predators of insects and other invertebrates, living in forest leaf litter and similar decaying plant matter. They are also commonly found under stones, and around freshwater margins. 
Almost 400 species are known to live on ocean shores that are submerged at high tide, including the pictured rove beetle, although these are much fewer than 1% of the worldwide total of Staphylinidae. Other species have adapted to live as inquilines in ant and termite colonies, and some live in mutualistic relationships with mammals whereby they eat fleas and other parasites, benefiting the host. A few species, notably those of the genus "Aleochara", are scavengers and carrion feeders, or are parasitoids of other insects, particularly of certain fly pupae.
