Larus cachinnans hybrid 1CY-2CY P463 December 2012 & March 2013, Deponie Pohlsche Heide - Minden, Germany (52°23'05N, 08°46'45E). Picture: Armin Deutsch.

Green P463 and metal (PLG) DN24753, ringed as pullus on May 27 2012 at J. Wytyckie, Wytyczno, Ursuzulin, east Poland, (52°25'48" N,  23°13'12" E). This is a mixed breeding colony in eastern Poland, with most birds breeding here cachinnans, but in this area also records of very few michahellis and/or argentatus are possible (see PDF). P463 close to cachinnans, but probably hybrid.

Compact bird, in this picture nicely showing jizz close to argentatus, which is the group around P463 as well.

below: note short legs, stubby bill, and pattern on coverts.

All scaps replaced, coverts and tertials still juvenile. In the next pictures, some resemblance to michahellis...

below: showing tail pattern, which strongly recalls cachinnans.
