The inhabitants of the seashore are exposed to a double set of predators. During submergence they are preyed upon by other marine creatures. When uncovered they encounter enemies from the land and air. On some parts of the British coast, seabirds exact a very heavy toll from shore populations during low tide. For example, oystercatchers (Haematopus ostralegus) eat huge numbers of cockles from the large, intertidal beds in South Wales. Studies in the Burry estuary indicate that as many as 500 cockles per bird per day can be taken. Oystercatchers prefer two-year-old cockles and in some circumstances, have been blamed for consuming up to 70 per cent of the stock of this age group. In other areas more bivalves are taken by flatfish when the tide is in than by waders when it is out.
