On his way home, the man saw a heron and went up to him and whispered what had happened. The heron told him to squat. When the snake snuck its head out, the heron caught it, pulled it out, and killed it. The farmer was worried that the snake’s poison might still be inside him, and the heron told him that the cure for snake poison was to cook and eat six white birds.
“You’re a white bird,” said the farmer. “You’ll do for a start.”
he grabbed the Heron, put it in a bag, and carried it home, where he hung it up while he told his wife what had happened.
“I’m surprised at you,” said the wife. “The bird does you a kindness, rids you of the evil in your belly, saves your life in fact, yet you catch it and talk of killing it.”
She immediately released the Heron and it flew away. But on its way, it gouged out her eyes.
