| Abstract |
Der Amerikanische Graureiher kann unbeweglich auf Beute lauern. Der Fangstoß wird so schnell und kraftvoll ausgeführt, daß Fische vom Schnabel aufgespießt werden. The film shows how motionlessly the great blue heron can stalk prey. As opposed to this the catching movement is carried out so rapidly and powerfully that the fish is speared on the bill. The fish are placed in the right position in the bill by means of jerky head movements and swallowed head first. |
