Lesser Black-backed Gull graellsii BTO GHxxxxx adult, March 30 2002, Maasvlakte, the Netherlands.
Adult bird ringed right leg with
an English BTO ring. It's a not unusual to find ringed adults from abroad
breeding here. So far, birds were found wearing rings from Britain,
Belgium and from Norway in this Dutch colony. There were more recoveries
of British birds in foreign colonies as well: a couple of records from
France and Spain can be found on the bottom of this
page. A few other sites mention ringed LBBG, for information look
Note small mirror. Probably female.
