A group of Herons warn off a big alligator from terrorizing their neighborhood.

Heron: A large fish-eating wading bird with long legs, a long S-shaped neck, and a long pointed bill. Unlike storks, ibises, and cranes, they fly with their necks retracted, not outstretched.    Alligator: A large semiaquatic reptile similar to a crocodile but with a broader and shorter head, native to the Americas and China.   Semiaquatic: Living partly on land and partly in water.
