The owl is an ambivalent symbol. It is a bird of wisdom. Being an attribute of the goddess Athena, the owl symbolizes wisdom, knowledge. Owls have the ability to see at night only turning their heads, they have a wise perceptive glance. This bird is credited with the gift of prophecy, perhaps because of its ability to see in the dark.
The owl was also a symbol of fearlessness at night, only this bird was able to know the secrets usually hidden to mortals. Nowadays, it is the emblem of insight and erudition.
