Many owls are associated with Minerva or Pallas Athene, the goddess of wisdom. She considered the owl a sacred bird, which gave the owl the reputation of having wisdom, and thus the saying “wise as an owl.”

Female scops-owls are usually larger than the males of their species, with owls of both sexes being compact in size and shape. All of the birds in this genus are small and agile. Scops-owls are colored in various brownish hues, sometimes with a lighter underside and/or face, which helps to camouflage them against the bark of trees. (

The Spotted Owl is closely tied to old-growth forests for nest and roost sites and the prey animals that live in this habitat. Spotted Owls are one of the few owls that have dark colored eyes.
