Black-tailed godwits are an elegant long legged bird about the size of a pigeon. In the summer they are found in the arctic where the Icelandic race of this species then migrates to Britain to spend the winter in relatively warmer weather. For this week's Living World Brett Westwood relives programmes from the Living World archives with an episode from 2013 which sees Chris Sperring visit a private estate in Hampshire where 2000 black tailed godwit visit their flooded water meadows along the River Avon in winter. Here Chris is guided by Pete Potts from Operation Godwit.
