”Wise as an owl” is a swedish saying, maybe in other languages too.
In ancient Greece, owls were often seen as a symbol of good fortune, and an owl is also associated with the Greek goddess of wisdom, Athena. Even in Harry Potter there is the smart owl Hedwig to help Harry. In Sweden there are several tv-programs for children where an wise owl has the lead role.
