The Perelle gull flock contained c 15 LBBGs this morning, of which at least five were locally ringed birds. Two were too distant to read, but three birds were identified - all ringed in 2012...and frustratingly none observed over the winter period. It's great to see them arriving back for the 2013 breeding season...albeit slowly as usual at this time of year.
