Oystercatcher (Haematopus ostralegus) is a coastal bird with strong three-toed legs and a straight strong beak. The color of these birds combines white and black colors (like a magpie). For nesting, oysterbirds choose pebbly, sandy, shell and rocky sea coasts in bays and bays, where there are shoals and a wide strip of littoral, which is exposed at low tide. Inland, oysterbirds inhabit the shores of rivers and lakes. In the European part of Russia, the oystercatcher nesting was also noted in the fields, and quite far from the water.

Reproduction

Each pair has a small nesting area protected by it, but at the same time dozens, and in suitable conditions, hundreds of pairs nest in the immediate vicinity. The nest is placed openly and is a simple shallow fossa. In a full clutch there are 3, sometimes 4 or 2 eggs. Both parents incubate, quite often replacing each other for 26-28 days. Down jackets leave the nest on the day of hatching, but at first they do not go far from it and are often heated by their parents. It is curious that adult magpie waders not only drive their chicks, but also feed them, that is, they bring them food in their beak, sometimes from a fairly considerable distance. Even half-fledged chicks cannot get their own food. Parents sometimes look for food right there, very close, and the chicks are indifferent to this. An adult bird brings an insect to the chick, holding it in its beak, sometimes puts it on the sand and stands motionless, lowering its beak and, as it were, pointing at its prey, until the chick finally grabs it.

Food

Food waders-forty varied. As a rule, they catch open prey on land and in shallow water, they can get animals buried in soft ground. The main food items of the oystercatcher are polychaetes, molluscs, crustaceans, insects and their larvae (dipterans, beetles, bat caterpillars, etc.)
