Photographing colour ringed birds is one thing but those carrying conventional metal rings pose something of a special challenge. If you are lucky enough to get close to the bird, trying to get a series of images that enables the ring number to be read is almost impossible. Fortunately a black headed gull with a ring marked Denmark spent long periods preening on top of the Boat House and Tredegar House Lake. This allowed me sufficient time to capture almost all of the ring. Alternatively a second ringed bird presented a more difficult challenge and I was unable to get any decent shots. Almost amongst the black headed gulls was a single Mediterranean Gull that eventually took flight leaving the lake. Four tufted duck were the others worthy of mention.
