El ave sin patas

I've heard that there's a kind of bird without legs that can only fly and fly, and sleep in the wind when it is tired. The bird only lands once in its life... that's when it dies.

....
I used to think there was a kind of bird that, once born, would keep flying until death. The fact is that the bird hasn't gone anywhere. It was dead from the beginning.
