cachinnans plumages

Larus cachinnans 1CY, September 10 2011, Utrecht, the Netherlands. Picture: Maarten van Kleinwee.

Moult in upper scaps. Second-generation, light-brown scapulars contrast with the dark-brown first-generation juvenile feathers. New dark feathers are also starting to appear on the flanks. The ring on the left tarsus was unfortunately not read, but its origin could possibly be Poland, Ukraine, etc.
