Larus cachinnans 8CY 4P58 October 07 2011, Katy Rybackie, Poland. Picture: Michal Polakowski.

Caspian Gull, green 4P58. Bird ringed as pullus on May 09 2004 at Wisla Wloclawek Tama, Poland. Bird from a mixed colony, parentage unknown.

In some ways this bird shows intermediacy. Its bill is easily within the range of Caspian, but in adult plumage it has a Herring Gull-like pale eye and angular head. However, as P10 is not fully grown yet, there remains much room for speculation. In general, maybe just within the limits for cachinnans.
