Brief introduction: The Barn Owl (Tyto alba guttata (Brehm, 1831)) is the most widespread bird of its kind found almost anywhere in the world except in polar and desert regions, and is also referred to as the Common Barn Owl. Contrary to other owls, the Barn Owl does not hoot but produces an ear-shattering scream-like sound.
