又赤嘴烏喻經云。昔有烏名曰拘耆（梁言赤嘴烏）遊在叢林樹產孺。諸子在樹上。時有拘耆。與一獼猴共為親厚。時叢樹間有一毒蛇。伺行不在。噉拘耆子無復遺餘。拘耆失子。悲鳴啼呼不知所在。熟自思惟知蛇所噉。獼猴歸見。問之何為。答曰。蛇噉我子了盡無餘。獼猴曰。我當報之。時毒蛇行。獼猴前嬈之。蛇怒纏獼猴。獼猴捉得頭曳至石上。磨破而死棄擲而還。拘耆踊躍。畜生尚有相報。何況於人。

Furthermore, the Chizuiwu yu jing says: Formerly there was a crow named Kaukkika (in the language of Liang, 'red-billed crow') that lived in a grove of trees and gave birth to young. Her chicks were in the tree. At that time, Kaukkika had a close friendship with a monkey. In the grove there was a poisonous snake, which watched until she went away and then devoured Kaukkika's chicks without leaving any behind. Having lost her chicks, Kaukkika wept and cried aloud, not knowing where they were. Thinking carefully, she realized they had been devoured by the snake. When the monkey returned and saw her, he asked what had happened. She replied: 'A snake devoured my chicks completely, leaving none behind.' The monkey said: 'I shall avenge them.' When the poisonous snake was moving, the monkey went forward and provoked it. Enraged, the snake coiled around the monkey. The monkey seized its head, dragged it onto a rock, smashed it to death, threw it aside, and returned. Kaukkika leaped with joy. Even beasts avenge one another, how much more so humans!
