Anyway, a feature that Lee's bird showed was an obvious reddish orbital ring. Have a look at this adult Herring Gull that was ringed on the tip on the tip on 14th January, and I'd previously mentioned I'd do a quick post on it. Presumably it emanates from a Baltic population - it was relatively dark mantled with a pretty prominent red/orange eye ring. The wing tip pattern is between argentatus and argenteus.
|Note the obviously bright orbital ring|
|Obvious white tip to P10 like an argentatus; dark notch to the outer web of P5 that you'd expect on an argenteus|
|Again, the obvious red/orange orbital ring visible here|
|Be interesting to see where YJ1T turns up; look at the obviously pink legs|
