A Flamingo stands on one leg

The behavior of a flamingo is very simple. They stand on one leg while they sleep and when another flamingo tries to hurt their baby, they will squawk and pick at that flamingo.

Flamingo's stand on one leg to regulate their body temperature.

Their legs are long so they can stand in shallow water and eat fish.

No one is really sure why flamingos stand on one leg. Scientist aren't even sure why flamingos stand on one leg. But one thing that has been proposed is that flamingos stand on one leg to relieve the pressure off the one side and res that side while the other side functions and controls the body. Then when that side has rested then they will alternate legs and do the same thing until they are fully rested and ready to go on about their business.
