The Call of a great Horned Owl

Great Horned Owls advertise their territories with deep, soft hoots with a stuttering rhythm: hoo-h'HOO-hoo-hoo. The male and female of a breeding pair may perform a duet of alternating calls, with the female's voice recognizably higher in pitch than the male's.

They can see objects with about five percent the amount of light that a human requires. >> Owls cannot move their eyes up, down, or side to side like humans can so they have evolved the ability to rotate their heads approximately 270 degrees. They have 14 neck bones.
