Ynghylch

The oystercatcher is very noisy wading bird with a loud 'peep-ing' call. On the coast, it specialises in eating shellfish, particularly cockles and mussels, which it either prises or hammers open with its strong, flattened bill. Originally a coastal species, the oystercatcher has moved further inland over the last 50 years to breed on waterways and lakes. Most UK birds still spend their winters by the sea, however, and are joined by birds from Norway and Iceland.
