A 'Baltic Gull' ???

Before anyone gets excited, its not a real Baltic Gull. However, on 2nd November 2010 Stephen Foster had an adult Black-headed Gull at Newcastle (on beach beside Glen River car park) with a black colour ring.  It had "P309" in white letters. He has now received the full details by e-mail of the origin of the bird and it was ringed in March 2010 at a dump in Lithuania!  The sighting is the farthest west of any Black-headed Gull ringed during the project. Any further sightings of this bird or others with black "Pxxx" rings should be submitted to Vytautas Pareigis.  pareigis@mail.lt
