Caspian Gull (Larus cachinnans), 3cy, 3.1.2006, Mosede Harbor, Sjælland

This Caspian Gull has an all characteristic plumage for the age class with a small white mirror visible on the outer most primary (p10) which is classic for 2nd winter cachinnans and very unusual in argentatus. For another much better photo of this individual please have a look at Netfugl.
