Caspian Gull ~ 1st. W ~ Dungeness, Kent - 21.09.13

Monday, 23 September 2013

Low tide and a walk out on the sand, only a few bait diggers which in-turn meant really low numbers of gull's, they were flighty and not confiding always keeping there distance. When you tried to move closer they just moved further away.
A white headed bird caught my eye and got Richard on it, no sooner had we found it, when it took flight up over the shingle ridge not to be seen again all weekend ...

Record shots were taken ...

Inner primaries dark on outer web, pale on inner giving the 'venetian blind'
