Abstract
Jagdmethoden des Dreifarbenreihers, der nicht nur lauert und pirscht, sondern durch schnelles Laufen kleine Fische am Ufer zusammentreibt. Mit dem dünnen Schnabel faßt er winzige Fische wie mit einer Pinzette.
The film shows the special hunting methods employed by the Louisiana heron, who not only lies in wait and stalks, but also drives smaller fish to the banks by means of rapid movements. With the slim bill he can grasp the tiny fish as with a pincette.
