After a short visit to Rufford on Wednesday, I decided to go back again yesterday. It had been very cold overnight, and more than half of the lake was covered in ice - always a good sign when checking gulls' legs!!
As soon as I got there, I could see that there were 400+ gulls out on the ice! The vast majority were Black-headed Gulls, with a minimum of 10 Common Gulls, 4 Lesser Black-backed Gulls and 1 Herring Gull. Over the course of 3 hours, I managed to spot 12 darvic-ringed Black-headed Gulls (217A, 258A, 273A, 279A, 281A, 293A, 295A, 297A, J0116, EUM3, P519 and V77K), 1 metal ringed Black-headed Gull (EL87245- a well known bird) and a new darvic ringed Common Gull (JN075 - an adult bird, ringed on 12th August 2020, near Oslo, Norway).
Of the 12 darviced birds, just 3 were new ones, I'd not seen before (279A, 295A and 297A). All are birds ringed at Center Parcs this winter.
In addition, there were 13 Mute Swans ( 9 adults and 4 juveniles, born last year), including a 1 metal ringed bird (W17357 - a bird that had been ringed on 10th February 2016, as a 5 i.e. born in 2015) and a darvic-ringed bird (CPF3/W48296 - another new bird, originally ringed as a 3 male, i.e. born that year, in Cheshire, on 16th November 2019).
