Scientists balanced a dead flamingo on one leg to unlock the bird's standing secret
Flamingos can stand on one leg for far longer than humans can. They can even do it while asleep. Now scientists have shed some more light on just how these pink birds manage such a balancing act without getting tired.
The researchers from the Georgia Institute of Technology in the US focused on one of the main theories used to explain this behaviour, the muscle fatigue hypothesis. The more a muscle is used, the more likely it is to become tired and so most animals standing on one leg need to regularly switch. But flamingos can use one leg for much longer periods of time without needing to switch. So the theory is that the leg holding them up doesn’t get fatigued.
The two scientists wanted to test if it was possible for flamingos to remain stable on only one leg without the need for active muscular effort. To see if a flamingo could do this, they used a novel method involving two dead flamingos, obtained from a local zoo.
