Another ringed gull in Rotherhithe

Last weekend, I noticed a ringed gull chilling out by the sailing club on Greenland Dock. With a distinctive red ring, this 1st-summer Herring Gull had been ringed by the NTGG (http://www.ntgg.org.uk/) - it had been ringed at Rainham on 18/12/2010 but hadn't been seen or reported since. The first ringed gull here in Rotherhithe for a while.
