25th Feb

At least one of the regular Iceland Gulls was seen at the Patch again and two first-winter Caspian Gulls were also seen. One of these was a new colour-ringed bird (yellow with black code X309) whilst the second bird was the same as the bird seen yesterday. This bird is also particularly interesting as analysis of photographs by Dante Shepherd show that it was also seen by him at the Thames Barrier on 14th February 2017. A second-winter Yellow-legged Gull was also seen.
