Owls are amazing creatures with many unique adaptations. For example, they can turn their heads 270 degrees. Their concave facial discs serve as parabolic sound reflectors, enhancing hearing and allowing them to detect faint rustles from a great distance.
Owl ears are located on the sides of the head, behind the eyes, and are usually hidden by the facial disc feathers. In some species, the ears are covered by a flap — the operculum. The "ear tufts" noticeable in some owls are actually decorative feathers, not ears.
Owl eyes are very large, comparable in size to the brain, and have a tubular shape rather than a spherical one. They are secured by sclerotic rings, providing stability and high light sensitivity, as well as binocular vision and depth perception. However, the range of eye movement in owls is minimal — less than 1.5 degrees.
Interestingly, due to the structure of the skull, one can look through an owl's ears into its head and see its eyes — their elongated tubular structure. This sight seems unusual and even a bit eerie.
