This well-camouflaged woodpecker used to be a common breeding bird in Britain, but is now only likely to be seen passing through on migration.

This sea snail is abundant on rocky shores around the UK. It is an active predator, feasting on mussels and barnacles before retreating to crevices to rest.

This elegant tern is named for the rosy flush to its summer plumage. With just one regular nesting colony, it is the rarest breeding seabird in the UK.

This secretive bird is a member of the rail family, related to coots and moorhens. The breeding call, a rasping rattle, is given mostly at night, sometimes for hours on end.

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.
