In Christian art and symbolism, the owl has various contradictory meanings – Satan/sinners or Christ – depending on how one looks at owls.

From Signs & Symbols in Christian Art by George Ferguson (Oxford University Press, 1961):

"The owl, since it hides in darkness and fears the light, has come to symbolize Satan, the Prince of Darkness. As Satan deceives humanity, so the owl is said to trick other birds, causing them to fall into the snares set by hunters.

"The owl also symbolizes solitude and, in this sense, appears in scenes of hermits at prayer. It[s] most ancient gift, however, is that of wisdom, and, with this meaning, it is sometimes shown with St. Jerome.

“In another sense, the owl is an attribute of Christ, who sacrificed Himself to save mankind, ‘To give light to them that sit in darkness and in the shadow of death. . .’ (Luke 1:79). This explains the presence of the owl in scenes of the Crucifixion.”

I assume it's probably the first meaning.

I found this while searching:

Pretty interesting. The site is trying to sell a book, but the info is good.

It’s sad to me that the owl has been “claimed” by those who are evil. I have a friend who’s a birdwatcher and owls are his favorite. Super good guy.

Informative post! Glad the Owl isn't always a bad symbol.
