Larus cachinnans adult PUEC April 25 2012, Gatovo - Minsk, Belarus. Picture: Dmitry Goncharov.
Bird ringed yellow PUEC and UKK L-009424, ringed as breeding adult male at the nest on May 19 2010 at Chernihiv Kosachivka Kyiv res Ukraine (51,1 30,95). Now in the rooftop breeding colony in Minsk.
Ringed as adult male in Ukraine, but if the birds in the picture form a pair, the bird on the nest should be labelled male, as it has much stronger proportions.
