This is the text (if you need help).
Scientists think they know how flamingos stand on one leg. Scientists have always wondered how they do this. A professor says the flamingo's hip and leg bones help it stand on one leg. The bones help the bird balance. Flamingos do not have to use their muscles a lot to stand on one leg.
Another researcher said the flamingo is unusual. Humans cannot stand on one leg, even for one hour. Even when we stand still, we're moving all the time because our muscles work so we don't fall over. Flamingos do not use many muscles to stand on one leg, so they save energy. Other birds also stand on one leg.
Back to the flamingos lesson.
