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 auditory system uses several cues for sound source localization, including time difference and level difference (or ...
The smallest owl—weighing as little as 31 g (1 + 3 ⁄ 32 oz) and measuring some 13.5 cm (5 + 1 ⁄ 4 in)—is the elf owl (Micrathene whitneyi). [6] Around the same diminutive length, although slightly heavier, are the lesser known long-whiskered owlet (Xenoglaux loweryi) and Tamaulipas pygmy owl (Glaucidium sanchezi). [6]
