Description
Summary:Lachmöwe. Hacken mit dem Schnabel, gegenseitiges heftiges Schlagen mit den Flügeln, abwechselnd Angriff und Flucht. : Two shots are shown of a male pecking at another male frome above. The third picture shows two males flying up into the air, pecking at each other. The next two shots show wing-beating. In these takings as well as in the next two long shots it can be seen that the various postures alternate regularly with either attack or escape, and usually with both.
