Larus cachinnans 1CY FF December 24 2011 2011, Leiden, the Netherlands. Picture: Maarten van Kleinwee.

Tibia yellow FF and metal Arnhem 5463250.

Some of the identification features of a first-calendar year Caspian Gull, distinguishing it from a European Herring Gull or a Yellow-legged Gull of the same age include:

• Thin high legs, showing much tibia (upper leg)
• Light-grey scapulars with distinctive dark anchor
• Moult in the wing coverts
• White head with light streaking and lack of an eye patch as for Yellow-legged
• Large black bill, somewhat parallel and no blunt tip
• Inner primaries with light inner web and dark outer web (creating a ‘Venetian blind’ effect)
• Small white tips to the inner primaries (apical spots)
• Narrow banding on the tail above the subterminal band
