This is the text (if you need help).
Scientists think they know how flamingos stand on one leg. We all love these beautiful birds doing this. Scientists have always wondered how they do this. Researchers say they have found the answer to this secret. A professor says the flamingo's skeleton helps it stand on one leg. Its hips and leg bones give the bird great balance. Flamingos do not have to use their muscles a lot to keep standing on one leg.
Another researcher said the flamingo is unique because it can stand on one leg. This is very difficult for humans, even for one hour. Most of us don't know that we're moving all the time. Even when we stand still, our muscles work so we don't fall over. Flamingos do not need to use many muscles to keep still. They can save energy by standing on one leg. Saving energy could be why other birds also stand on one leg.
