It is an extremely adaptable bird with a vast range and is the most widely distributed true owl in the ...
Owls lock onto prey by using sound localization. [ 2 ] 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.
The northern saw-whet owl (Aegolius acadicus) is a species of small owl in the family Strigidae. The species is native to North America. Saw-whet owls of the genus Aegolius are some of the smallest owl species in North America. They can be found in dense thickets, often at eye level, although they can also be found some 20 ft (6.1 m) up.
Human auditory system. Sound localization is the process of determining the location of a sound source. The brain utilizes subtle differences in intensity, spectral, and timing cues to localize sound sources. [3][4][5] Localization can be described in terms of three-dimensional position: the azimuth or horizontal angle, the elevation or ...
Greater yellowlegs. Long-billed curlew. Scolopacidae is a large diverse family of small to medium-sized shorebirds including the sandpipers, curlews, godwits, shanks, tattlers, woodcocks, snipes, dowitchers, and phalaropes.

A member of the true owl family, Strigidae, they belong to the genus Strix, which is also the origin of the family's ...
Hearing in owls is highly sensitive and the ears are asymmetrical allowing the owl to localise a sound in multiple directions. Owls can pinpoint the position of prey, such as a squeaking mouse, by computing when the sound from the object reaches the owl's ears. If the sound reaches the left ear first, the mouse must be to the left of the owl ...
