An eagle swooped down from a lofty cliff and snatched a sheep from the flock.
When the crow saw this, he wanted to do the same thing. "I'm strong! I've got wings! And a sheep would be something very nice to eat!"
So, squawking loudly, the crow swooped down and landed on a sheep, but instead of carrying the sheep away, all he did was get his feet tangled in the wool. He couldn't even fly away!
The shepherd saw the crow and laughed.
"You thought you were an eagle," he said, "but now you know: you're only a crow."
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 431 in the book, which is Perry 2. In the original story the shepherd grabs the crow, clips its wings, and gives him to his son as a pet.
