First the Great Black-backed Gull, that I saw in RSPB Titchwell. At the time I thought it was a Norwegian bird, so I was very pleased when I received an e-mail from Norway confirming this. The bird in question had been ringed as a pullus in July 2014, and had been recorded 3 times in the area in the next few days. My record was the first sighting since then, and the first one outside Norway.
In addition to these 2 gulls, I also spotted a couple of colour ringed Herring Gulls in St Ives, Cornwall last week. Again, a quick search of the European Color ringing website ( see here), suggested that these 2 birds were local born birds, and an email from the West Cornwall Ringing Group confirmed this. Both gulls had been ringed in St Ives in June 2015 as part of a study to investigate the movements, and feeding habits, of these gulls. Both birds have been recorded in St Ives, with one visiting the nearby RSPB Hayle Estuary Reserve. Here's a couple of pictures of both birds.
