The Escaped Jackdaw
Man caught a Jackdaw and tied a piece of string to one of its legs, and then gave it to his children for a pet.
But the Jackdaw didn't at all like having to live with people; so, after a while, when he seemed to have become fairly tame and they didn't watch him so closely, he slipped away and flew back to his old haunts.
Unfortunately, the string was still on his leg, and before long it got entangled in the branches of a tree and the Jackdaw couldn't get free, try as he would.
He saw it was all up with him, and cried in despair, "Alas, in gaining my freedom I have lost my life."
