|Colin says: The Pied Wagtail - also known as a White Wagtail.
A delightful small, long-tailed and rather sprightly black and white bird. When not standing and frantically wagging its tail up and down it can be seen dashing about over lawns or car parks in search of food. It frequently calls when in its undulating flight and often gathers at dusk to form large roosts in city centres. This one was all alone in a field adjacent to Earnse bay.
