Order: Charadriiformes Family: Haematopodidae The oystercatchers are large, obvious and noisy plover-like birds, with strong bills used for smashing or prising open molluscs.
They are small to medium-sized birds with compact bodies, short, thick necks and long, usually pointed, wings.
Different lengths of legs and bills enable multiple species to feed in the same habitat, particularly on the coast, without direct competition for food.
Terns are a group of generally medium to large seabirds typically with gray or white plumage, often with black markings on the head.

They lack the powder down that other wading birds such as herons, spoonbills, and ibises use to clean off fish slime.
Having the largest wingspan-to-body-weight ratio of any bird, they are essentially aerial, able to stay aloft for more than a week.
Members of Ardeidae fly with their necks retracted, unlike other long-necked birds such as storks, ibises and spoonbills.
