1cy Lesser Black-backed Gull

A long time since last time I saw a LBBG with this amount of white on its belly. Made me think about cach for quite a long time actually... Of course there are not many thinks fitting with cach today, but it was a different story yesterday ;)

Lesser Black-backed Gull, Bispevika/Middelalderparken 25.08 

Tailpattern fits good with Caspian, but even better with LBBG
This bird actually shows a window in primaries, not very normal
for a LBBG, but some individuals have it.
