Three Hundred Æsop's Fables/The Birds, the Beasts, and the Bat
THE BIRDS, THE BEASTS, AND THE BAT.
The Birds waged war with the Beasts, and each party were by turns the conquerors. A Bat, tearing the uncertain issues of the fight, always betook himself to that side which was the strongest. When peace was proclaimed, his deceitful conduct was apparent to both the combatants. Therefore being condemned by each for his treachery, he was driven forth from the light of day, and henceforth concealed himself in dark hiding-places, flying always alone and at night.
