Flamingos often stand on one leg. The reason for this behavior is not fully known. A leg is tucked beneath the body, because the flamingo like some other animals has the ability to have half of its body go into a state of sleep, and when one side is rested, the flamingo will swap leg and then let the other half sleep, but this has not been proven. It is often suggested that this is done in part to keep the legs from getting wet, in addition to conserving energy.
At first glance, the flamingos appear to be all pink. there is a hidden striking feature that is only visible when the Flamingo is in flight or spreading its wings
There are 12 principal flight feathers located on each wing. These black feathers are visible when the wings are extended.
