Larus cachinnans 1CY PNDT August 30 2013, Deponie Pohlsche Heide - Minden, Germany (52°23'05N, 08°46'45E). Picture: Armin Deutsch.

Yellow PNDT, ringed as pullus on May 24 2013 at Kozielno, Paczkow, S-SW Poland, (50°28' N,  16°58' E).

Recoveries:

PNDT	24-5-2013	ZB. Kozielno, Paczkow	50°28'35" N	16°58'54" E
PNDT	30-8-2013	Deponie Pohlsche Heide	52°23'04"	08°46'53"
PNDT	30-8-2013	Wietersheim	52°19'54"	08°56'43"

In this area are mixed breeding colonies (near Katowice), with far most birds breeding here are cachinnans, but in this area also records of very few michahellis from the south (e.g. ringed female from Italy) and argentatus from eastern Germany are possible (see PDF).

PNDT is cachinnans. Very irregular moult sequence, with jumpy pattern in GC, MC and upper LC. Scapulars too are a mix of (older) juvenile and recently replaced 2nd gen feathers. Already replacing upper tertials.
