A quick check of the high tide roost at Bellegreve Bay this morning resulted in a count of c 30 Mediterranean Gulls, including a French-ringed bird.
With Camille Duponcheel's usual stunning efficiency I already have the details for Med Gull Green RU18, seen in Bellegreve Bay this morning. It was ringed as a chick on Noirmoutier Island, Vendee, France in June 2014. It was subsequently seen in Devon, England that autumn, before being seen in Jersey earlier this month.
Med Gulls really do have one of the more complex and interesting dispersal/migration strategies of all the European gulls!
