So where has it been since? Who knows but presumably it is now breeding in eastern France, Switzerland or Germany, where there are a lot of lakes and few birders. And why do I speculate this orgin? From the limited evidence I have from this bird's previous movements and three ringing recoveries of Yellow-legged Gulls that I've had in London/Essex - two from the big Swiss lakes and one from southern Germany.
I had a further three juvenile Yellow-legged Gulls at Thames Barrier Park this afternoon with Dante and Jamie P, while there were three more at the O2 this evening - felt a bit cheated with this paltry total given that we'd waded through the hordes of Bros fans on their way to listen to a couple of peroxide blonds from yesteryear sing 'When Will I Be Famous'.
