I thought I would start a new thread on which photos of colour-ringed gulls could be posted - I hope others will add theirs. I will start with three from Southwold, Suffolk:-
1. Lesser Black-backed JHZ2 on black from Norway
2. Mediterranean AAHT - 05 October 2009 (from Germany)
3. Mediterranean AANZ - 05 Feb 2009 (from Germany?)
I will post the details as I get them.
Please post your images and we might build up a bit of an archive or resource.
