These species include barn owls (Tyto alba), northern saw-whet owls (Aegolius acadicus), and long-eared owls (Asio otus). The barn owl (Tyto alba) is the most commonly studied for sound localization because they use similar methods to humans for interpreting interaural time differences in the horizontal plane. [4]

Barn owl in flight. The barn owl is a medium-sized, pale-coloured owl with long wings and a short, squarish tail. There is considerable size variation across the subspecies, with a typical specimen measuring about 33 to 39 cm (13 to 15 in) in overall length, with a wingspan of some 80 to 95 cm (31 to 37 in).
The American barn owl is a medium-sized, pale-coloured owl with long wings and a short, squarish tail. 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.

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.
Some, like owls and nighthawks, are predominantly nocturnal whereas others do specific tasks, like migrating, nocturnally.

In ornithology, the facial disc is the concave collection of feathers on the face of some birds —most notably owls —surrounding the eyes. The concavity of the facial disc forms a circular paraboloid that collects sound waves and directs those waves towards the owl's ears. The feathers making up this disc can be adjusted by the bird to alter ...
