Three species that are sometimes considered to be a single species known as barn owl or common barn owl: Western barn owl Tyto alba, from Europe, Africa, and the Middle East; American barn owl Tyto furcata, from the Americas; Eastern barn owl Tyto javanica, from southeast Asia and Australasia; Andaman masked owl Tyto deroepstorffi endemic to ...
The American barn owl is a medium-sized, pale-coloured owl with long wings and a short, squarish tail. [3] However, the largest-bodied race of barn owl, T. f. furcata from Cuba and Jamaica, is also an island race, albeit being found on more sizeable islands with larger prey and few larger owls competing for dietary resources.

Sound localization is an animal’s ability to identify the origin of a sound in distance and direction. [3] Several owl species have ears that are asymmetrical in size and location, which enhances this ability. These species include barn owls (Tyto alba), northern saw-whet owls (Aegolius acadicus), and long-eared owls (Asio otus).
The eastern barn owl is native to southeastern Asia and Australasia. The eastern barn owl is nocturnal over most of its range, but in some Pacific islands, it also hunts by day. They specialise in hunting animals on the ground, and nearly all of their food consists of small mammals which they locate by sound, their hearing being very acute.
This asymmetry allows the barn owl to determine the elevation of a sound by comparing sound levels between its two ears. Interaural time differences provide the owl with information regarding a sound’s azimuth; sound will reach the ear closer to the sound source before reaching the farther ear, and this time difference can be detected and ...

The barn owl has the most visually prominent facial disc, measuring about 110 mm (Simmons), while the great grey owl has the largest disc of any bird. Due to shared inner ear anatomy with barn owls, [ 1 ] it is theorized that the feathered dinosaur Mononykus may also have had a facial disc.
