Larus cachinnans hybrid? 2cy-3cy PLG DN-25884 October 2009 & September 2010, Westkapelle, the Netherlands. Picture: Theo Muusse & Ies Meulmeester.

Ringed as pullus in a mixed colony, probably a hybrid between cachinnans x argentatus. Ringed as pullus on June 01 2008 at Kozielno Paczkow Opolskie, Poland.

Note tiny mirror on 2nd gen P10. Especially note on this individual the atypical build, head and bill shape. The median and lesser coverts show very dark centre and the greater coverts are very fine barred.
