Screech owls are typical owls belonging to the genus Megascops with 22 living species.For most of the 20th century, this genus was merged with the Old World scops owls in Otus, but nowadays it is again considered separately based on a range of behavioral, biogeographical, morphological, and DNA sequence data.
ITD occurs whenever the distance from the source of sound to the two ears is different, resulting in differences in the arrival times of the sound at the two ears. 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.

The bearded screech owl is the smallest of its genus in North America. It is 16 to 20 cm (6.3 to 7.9 in) long; males weigh about 63 g (2.2 oz) and females 72 g (2.5 oz). In addition to being heavier, females have somewhat longer wings and tails, and in both sexes the wings extend past the tail.
The black-capped screech owl's primary song is "a long fast trill, very faint before increasing in volume, [and] ending abruptly". Its secondary song is short, with a "bouncing-ball rhythm". Both sexes sing in duet and the female's voice is higher pitched. [4]
