Latvian ringed Black-headed Gull

A little while ago (25 July) I found a yellow ringed (KJZ4) Black-headed Gull on the Leri. Got a reply to my email today which confirmed my initial suspicions that the bird was of Latvian origin. It was ringed in June 2017 in Saulkalne, Latvia. It was then seen in the Netherlands and then in Leicestershire in October 2017. I think this is the largest movement I have seen out of any colour-ringed bird I have reported.
