I had my first visit to Rufford CP on Friday, to see if there were any returning Black-headed Gulls. There were 40 birds when I arrived, including a new bird for me, X25K.
Black-headed Gull X25K
This bird was ringed on a small island, called Riether Werder in the Neuwerper See on the German/Poland border, as an adult breeding bird, in May 2017. Since then it has been reported twice in Derbyshire! The first sighting was at Sinfin Moor in January 2020, and then in Staveley in December 2020.
