I've had a couple of visits to Rufford recently, on the 12th March and today.
The visit on 12th had just 50 Black-headed Gulls, but did include several colour-ringed birds, namely 258A, 277A, 284A, 294A and 202B.
Today's visit was much quieter with just 20 Black-headed Gulls present and just JO116 ( a Norwegian-ringed bird) seen.
