Once upon a time, they say, eagles had the most beautiful singing voices to go with their beautiful feathers. Then they heard the horses neighing in the fields. "That's an interesting noise," they said to each other.
"We should learn to make a sound like that." So they began to practise it. But the more they tried, the louder and uglier their squawking became. "It's no good," they said at last. "We'll have to go back to singing like we used to." They looked at each other. "How did our old songs go?" But nobody could remember them, and all they were left with was the horrible noise they make today.
