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.

This asymmetry allows the barn owl to determine the elevation of a sound by comparing sound levels between its two ears. Interaural time differences provide the owl with information regarding a sound’s azimuth; sound will reach the ear closer to the sound source before reaching the farther ear, and this time difference can be detected and ...
Crepuscular birds include the common nighthawk, barn owl, [19] owlet-nightjar, chimney swift, American woodcock, spotted crake, white-breasted waterhen, [20] European nightjars, [8] and common buzzards. [21] Many moths, beetles, flies, and other insects are crepuscular and vespertine.
The barn owl’s brilliant white underbelly is the key to its success as a nocturnal hunter, allowing the bird to camouflage itself against the moon, according to new research.
