English KS1/KS2: Aesop's Fables - 33. The Heron and the Fish
A heron walks along a riverbank, behaving as if he is a king. The other animals and birds feign respect but laugh at him behind his back.
The heron hunts fish by standing very still in the water, on one leg, and waiting for fish to swim past. He cannot hunt when the other animals are there, making a noise and splashing around. He waits until they have finished, then wades out into the river. However, he refuses to catch the various small and medium-sized fish that swim past, thinking that only a great salmon is good enough for him No salmon comes, so he ends up with nothing to eat.
