The bird family Tytonidae, which includes the barn owls Tyto and the bay owls Phodilus, is 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 ...
The inner ear of barn owls includes the vestibular organ, cochlea, and auditory nerve. The anatomy of the inner ear in barn owls was studied in an experiment where three owls were utilized and fixed at laboratories by the intravascular perfusion of 1% formaldehyde and 1.25% glutaraldehyde in a 0.1 phosphate buffer.

The barn owls (Tyto species, particularly Tyto alba) are the most widely distributed group of owls in the world. They are medium-sized owls with large heads and characteristic heart-shaped faces. They have long, strong legs with powerful talons. The term may be used to describe:
The American barn owl is a medium-sized, pale-coloured owl with long wings and a short, squarish tail. [3] 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.

When disturbed at its roosting site, an angry barn owl lowers its head and sways it from side to side, or the head may be lowered and stretched forward and the wings drooped while the bird emits hisses and makes snapping noises with its beak. A defensive attitude involves lying flat on the ground or crouching with wings spread out. [17]
Puerto Rican barn owl (Tyto cavatica) found in Puerto Rico - may still have existed up to 1912; possibly a subspecies of the ashy-faced owl (Tyto glaucops) Noel's barn owl (Tyto noeli) found in Cuba; Rivero's barn owl (Tyto riveroi) found in Cuba; Cuban barn owl (Tyto sp.) found in Cuba; Hispaniolan barn owl (Tyto ostologa) found in Hispaniola
The head movements need not be actively produced; accurate vertical localization occurred in a similar setup when the head rotation was produced passively, by seating the blindfolded subject in a rotating chair. As long as the dynamic changes in binaural cues accompanied a perceived head rotation, the synthesized elevation was perceived. [14]
Brains of an emu, a kiwi, a barn owl, and a pigeon, with visual processing areas labelled. The avian brain is the central organ of the nervous system in birds. Birds possess large, complex brains, which process, integrate, and coordinate information received from the environment and make decisions on how to respond with the rest of the body.
