There was once a great battle between the birds and the beasts. The beasts won the battle. On their way home, one of the beasts met a bat. "oh, you are a bird. I'll eat you up," said the beast. "no, no, "said the bat. "I am not a bird. I am a mouse. Look at the fur all over my body, and at my mouth with its sharp teeth," and the bat safely ran away. A few days later there was a second battle. This time the birds won. When one of the birds found the bat, he said, "you are a mouse. I must kill you." "no, no," said the bat. "I am not a mouse. I am a bird. Look at my wings. After several battles between the birds and the beasts, they were friends again. But they could not trust the bat. And the bat had to hide in dark places in the daytime. This is why a bat flies about only at night.
