Common Tern
Common Tern / sterna hirundo. Straws Bridge, Derbyshire. 16/05/20.
The image shows a pair of Common Terns who returned to a breeding lake in mid-May. They discovered the tern raft was fully occupied with nesting Black-headed Gulls. Despite them launching noisy aerial attacks from every angle over a two day period, the gulls would not be shifted and so they moved on. I think it was only to another body of water locally, because they were seen making brief visits most days.
