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. These species include barn owls (Tyto alba), northern saw-whet owls (Aegolius acadicus), and long-eared owls (Asio otus).
Eric Knudsen. Eric Knudsen is a professor of neurobiology at Stanford University. He is best known for his discovery, along with Masakazu Konishi, of a brain map of sound location in two dimensions in the barn owl, tyto alba. His work has contributed to the understanding of information processing in the auditory system of the barn owl, the ...
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.

Barn owl. The barn owl (particularly Tyto alba) is the most widely distributed group of owls in the world. They are medium to large owls with large heads and characteristic heart-shaped faces. They have long, strong legs with powerful talons. The term may be used to describe: Barn-owl, the family of Tytonidae. Tyto, a genus of birds in Tytonidae.
Barn-owls (family Tytonidae) are one of the two families of owls, the other being the true owls or typical owls, Strigidae. They are medium to large owls with large heads and characteristic heart-shaped faces. They have long, strong legs with powerful talons. They also differ from the Strigidae in structural details relating in particular to ...
[22] [23] This optimizes the owl's ability to silently fly to capture prey without the prey hearing the owl first as it flies, and to hear any noise the prey makes. It also allows the owl to monitor the sound output from its flight pattern. A great horned owl with wet feathers, waiting out a rainstorm
The eastern barn owl (Tyto javanica) is usually considered a subspecies group and together with the American barn owl group, the western barn owl group, and sometimes the Andaman masked owl make up the barn owl. The cosmopolitan barn owl is recognized by most taxonomic authorities. A few (including the International Ornithologists' Union ...
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 ...
