The Dove and the Ant
When an ant tried to drink from a stream he almost drowned. Observing this, a dove, perched on a tree above, picked a leaf from a twig and dropped it into the pool. The ant quickly climbed upon the leaf and was rescued. Sometimes afterwards a bird-catcher was trying to catch birds with a snare. The ant noticed this and stung the man's foot, causing him to make a mess of the snare. The dove noticing all this flew off to safety.
Moral: One good turn deserves another.
