The Owl is found on every continent except Antarctica
Owls can hunt in complete darkness, using only their hearing
Screech owls come in three color phases - red, grey and brown. Same bird, different colors.
Owls have a flap in their ear so they can actually shut their ears when it's too noisy.
Owls have asymmetrical ears - one is located higher than the other to aid in triangulation.
Owls have serrated edges on their flight feathers so their wings make no noise when they flap. They can fly in complete silence.
Unlike a lot of owls, Barred Owls have no feathers on their feet so they don't get waterlogged when hunting for fish in streams.
Barn Owls have over 20 different vocalizations - none of them are a Hoot.
Great Horned Owls have eyes the same size as ours, despite their smaller head.
Owls have 270 degrees of rotation in their necks. This is because they have more vertebrae in their neck than mammals.
Owls have such large eyes that there's no room in their skull for eye muscles. They must move their whole head to look around.
