Lachmöwe. Das Männchen beim Anlocken eines Weibchens in seinem Revier, Treffen und Balzen der Partner.

The first picture show an unmated male standing on its territory and responding to passing birds by the oblique posture and long call and an occasional forward posture. The next four scenes each give a complete meeting ceremony after a female has alighted near a male. In the last shot, both birds walk towards each other in the forward posture, then turn parallel to each other and end by head flagging.
