A crane and an eagle were soaring through the sky when the eagle saw with his eagle-eye something white down on the ground.
"I see a lamb down there!" said the eagle. "Do you see it too?"
"My eyesight isn't as good as yours," replied the crane. "But I know that farmers often lay traps here for birds. I'd advise you to be careful."
"It's a lamb, you fool!" retorted the eagle. "Maybe you can't see it, but I can!"
The eagle then swooped down like a bolt of lightning, only to be caught and killed in the farmer's snare.
Inspired by: Mille Fabulae et Una, a collection of Latin fables that I've edited, free to read online. I am not translating the Latin here; instead, I am just telling a 100-word version of the fable.
Notes: This is fable 474 in the book; the story is not in Perry's catalog. It is adapted from the French fabulist Desbillons.
