Work to complete a hide and nesting bank for Sand Martins has been completed at Attenborough Nature Reserve in Nottinghamshire.

It is believed to be the first of its kind, incorporating an artificial nesting bank made of clay pipes and breeze blocks and a hide.

Cameras inside the 150 nesting tunnels will transmit images into the hide.
