Tweet of the Day is a series of fascinating stories about the British birds inspired by their calls and songs.

Michaela Strachen presents the oystercatcher. These black and white waders used to be called sea-pies because of their pied plumage, which contrasts sharply with their pink legs and long red bill. Oystercatchers don't often eat oysters. Instead they use their powerful bill to break into mussels on rocks or probe for cockles in the mud of estuaries.
