Despite its name, the large blue is a fairly small butterfly, but the largest of our blues. It was declared extinct in 1979, but reintroduced in the 1980s and now survives in southern England.

As the UK’s tallest bird the common crane is instantly recognisable with the ruffle of tail feathers and very long legs. Their bugling call is also very distinctive.

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.

This tiny gamebird is rarely seen, but its distinctive "wet my lips" call can be heard ringing out over areas of farmland on summer evenings.
