The eastern screech owl (Megascops asio) or eastern screech-owl, is a small owl that is relatively common in Eastern North America, from Mexico to Canada. [ 1 ] [ 3 ] This species resides in most types of woodland habitats across its range, and is relatively adaptable to urban and developed areas compared to other owls.
A screech owl fossil from the Late Pliocene of Kansas [4] (which is almost identical to eastern and western screech owls) indicates a longstanding presence of these birds in the Americas, while coeval scops owl fossils very similar to the Eurasian scops owl have been found at S'Onix on Majorca. [5]
When the sound source is directly in front of the owl, there is no ITD, i.e. the ITD is zero. In sound localization, ITDs are used as cues for location in the azimuth. ITD changes systematically with azimuth. Sounds to the right arrive first at the right ear; sounds to the left arrive first at the left ear.

The primary call is an accelerating series of short whistles at an increasing tempo or a short then long trill falling slightly at end. Other calls: barking and chuckling, similar to the eastern screech owl. [6] They also make a high pitched screech. The two primary songs for the Western Screech Owl are the bounce and double trill.
Further adaptations in the wing feathers eliminate sound caused by flying, aiding both the hearing of the owl listening for hidden prey and keeping the prey unaware of the owl. Barn owls overall are darker on the back than the front, usually an orange-brown colour, the front being a paler version of the back or mottled, although considerable ...
