Yesterday I got recovery from Romania. Herring Gull ringing by me (01/05/2012) in Lublin province on the Vistula river (breeding colony) was found on 08/02/2014 in Bucharest, Romania. So, bird wintering in area of the Black Sea, which is very unusual for this species.

 Maybe the bird is a hybrid (F2 or backross cach x arg) but some influence other species is barely detectable - if it all.
