Mew Gull canus E20J 3+cy, December 03 2010, Zoetermeerseplas - Zoetermeer, The Netherlands. Picture: Maarten van Kleinwee.

Ringed on December 03 2010; ringed darvic white E20J. Possibly third-calendar year Mew Gull, aged by the black markings on the outer primary coverts. However, such neatly demarcated black spots on the primary coverts may still be present in 8cy and even 22cy birds.
