Quite an ordinary 1cy Herring imo.There´s no visible covert moult and together with structure, all features - such as scapular, coverts, tertial and bill it looks good for a pure Herring.<a href="http://www.gull-research.org/hg/HG1CY11.htm" target="_blank">http://www.gull-research.org/hg/HG1CY11.htm</a><a href="http://www.gull-research.org/hg/HG1CY12.htm" target="_blank">http://www.gull-research.org/hg/HG1CY12.htm</a>The swedish gull linked by Lou was discussed by me and David Erterius and the gull vas taken by Hans Larsson.The issue was - whether it has some argentatus genes or if it  could simply be a within variation Caspian Gull. Although perhaps not easy to put at rest as a pure Caspian or even a Herring x Caspian for that matter, the feeling is that for a hybrid one would want a further set of characters indicating stronger  the hybrid theory.JanJ</blockquote>
