Until this sighting on the 14th December sightings of our Great Black Back Gulls as with our Herring Gulls has been relatively routine coastal sightings with a couple of exceptions one being the sightings of P:82B.

Ringed as a Pulli on the 26th June 2015 on the Portland Harbour Break Waters.
first sighting came in January 2017 from Little Marlow,  Buckingham shire from Jim Rose.
Second sighting came from the Axe Estuary, Devon October 2017 from Ian McLean.
Third sighting was back at Little Marlow on the 14th December 2017 from Jim Rose

Is this a normal movement of a GBBGull or an exceptional one, only time, luck and sightings will tell us?
