Birdwatching in Cornwall
Cornwall has four main bird-rich estuaries, the Hayle and the Camel on the Atlantic coast and those of the Tamar, the border with Devon and the Fal on the sheltered southern coast.

These estuaries provide a wide variety of habitats for resident and migrating birds, rocky ledges, muddy creeks, salt marshes and freshwater coves, which provide shelter for a diversity of birdlife, herons, herring gulls, buzzards, oystercatchers, golden plovers, mute swans and redshanks among them.
