The bat said that he was ashamed of the dove as he thought that the dove could not praise the owl properly.

The owl and the bat fell upon the dove and drove her out into the dark and stormy night.

The bat cannot fly at broad day light and the owl cannot hunt or feed himself unless it is dark. Thus the bat and the owl were punished at the end.

The dove's name shall be used by poets as long as the world lasts to rhyme with "Love". Thus the dove got reward.
