Larus armenicus 1cy, 15 December 2010, Maagan Michael, Israel. Picture: Amir Ben Dov.
Obvious difference between fresh 2nd gen feathers (inner wing-coverts and scapulars) and brown 1st gen (juvenile) feathers in wing-coverts. Active post-juv moult in lesser coverts, with missing feathers? All flight feather still juvenile.
