Larus cachinnans 1CY 29P4 October 09 2014, Boulogne-sur-Mer, France. Picture: Jean-Michel Sauvage.
Red ring from Poland used in 2014. 300 pulli were ringed this year, all pulli in May 2014
at the Kozielno colony, Paczkow, Poland, ringed by Jacek Betleja.
Heavily streaked bird with strong high bill. Probably all falling just within limits for pure cachinnans, but some michahellis influence is also possible in this colony.
