Wing-tagged Mongolian Gull AC82 reported on March 23 2013, Jinzhou Bay, Dalian (39°06'N, 121°39'E). Originally ringed as pullus on June 25 1989, at Toynak island in Lake Baikal. It was then trapped again as an adult bird on May 20 2005 at Airchan Nuur, Mongolia, the metal leg ring was replaced and a wing tag (“AC82") attached.  Qingquan’s sighting is the first since the tag was fixed in 2005 and, with the original ringing data from Russia, proves that this bird is almost 24 years old (25CY)!
