A much-loved garden bird, the blackbird is famous for its harmonious song. In winter, our resident birds are joined by migrants from Scandinavia and the Baltics.

A pretty, little gull, the kittiwake can be spotted nesting in colonies on clifftops and rock ledges around the UK's coast. It spends the winter out at sea.

Native oysters are a staple of our seas and our plates - but our love of their taste has lead to a sharp decline all around the UK.

These winter visitors are close relatives of the chaffinch and can often be found in the same flocks, where their white rump and nasal calls give them away.
