Also recently I've found a few Great Black-backed Gulls bearing colour rings and have had some bits of information back, with the most interesting being an adult bird seen last week that was ringed in 2008 in southern Norway as a juvenile, and being last seen in 2010 in northern France.

this 2nd winter Great Black-backed Gull (JC383) was ringed in southern Norway on 04/07/2016 and was last recorded on 18/04/2017 further east along the same coastline, having been to northern France for the winter in between.
