Yesterday’s inbox contained an email with the life history of this ringed Lesser black-backed gull I found at Cosmeston Lakes Country Park and reported to the BTO’s ringers on 5 October. This bird was first ringed on Flat Holm Island, in the Bristol Channel off the south Wales coast, on 1 July 2017. A couple of months later, on 6 September, it was spotted at Cosmeston, and then it headed 1200 kms south to Matosinhos, a port and fishing town in Portugal, where it was seen twice in October 2017, on the 27th and again on the 31st. The bird wasn’t seen again until my recent report so it’s anybody’s guess where it’s been for the past three years.
