This improves the owl’s ability to capture prey while flying silently, without the prey hearing the owl first as it travels and hearing any noise the prey makes. The sound level released falls within the owl’s common prey’s average hearing spectrum and within the owl’s optimum hearing range, thanks to these unique features that attenuate noise frequencies over 2 kHz.
A velvety texture covers the surface of the flying feathers, which absorbs the sound of the wing moving. Serrations are more likely to mitigate aerodynamic disturbances than they are to reduce noise. The owl’s remiges have serrated edges that reduce wing flapping to a near-silent process. Owl feathers are often more significant than those of other birds, with fewer radiating, a longer pendulum, and smooth edges achieved by various rachis structures.
Most owls are nocturnal, and their ability to fly silently provides them a significant edge over their prey, who is listening for even the tiniest sound in the night.īecause prey can typically see an owl coming, a quiet, sluggish flight isn’t as crucial for diurnal and crepuscular owls. Flight and featuresĬompared to other birds of prey, most owls have a natural ability to fly nearly silently and slowly. These marks are more prevalent in open-habitat species and are considered to be utilized for communication. Although several species have facial and head markings like face masks, ear tufts, and vividly colored irises, owl plumage is cryptic. As previously stated, owls’ facial discs aid them in funneling prey sounds to their ears.įor improved directional localization, several animals put these discs asymmetrically. This impact is bolstered by other anastomoses between the carotid and vertebral arteries.ĭistinct owl species make different sounds this diversity of cries helps owls find mates or announce their presence to prospective competitors, and ornithologists and birders locate and differentiate these birds. They also have circulatory system adaptations that allow them to rotate without cutting off blood to the brain.
Owls have 14 neck vertebrae compared to seven in humans, giving them additional flexibility in their necks. Owls’ heads and necks may swivel up to 270 degrees. Their distant eyesight is superb, especially in low light. Filoplumes, hair-like feathers on the beak and foot that function as “feelers”, allow owls to detect caught prey. Owls can’t see anything within a few millimeters of their eyes since they’re farsighted. Although owls have binocular vision, their big eyes, like those of most other birds, are fixed in their sockets, requiring them to swivel their entire heads to change viewpoints. Most birds of prey have eyes on the sides of their heads, but the owl’s forward-facing eyes are stereoscopic, allowing them the better sense of depth awareness required for low-light hunting. The disc’s feathers may be modified to concentrate sounds from various distances onto the owls’ asymmetrically positioned ear canals. Owls have big, forward-facing eyes and ear-holes, a hawk-like a beak, a plain face, and a prominent circle of feathers around each eye called a facial disc. Except for the polar ice caps and a few isolated islands, they can be found in every part of the world. However, a few species specialize in fish hunting. Small animals, insects, and other birds are the primary prey of owls. The diurnal northern hawk-owl and the gregarious burrowing owl are two exceptions. Owls belong to the Strigiformes order, containing approximately 200 species of primarily nighttime and lonely birds of prey with a straight stance, a big, broad head, stereoscopic eyesight, duplex hearing, sharp claws, and quiet flying feathers. In Greece, it is known as the symbol of wisdom.
Owl has different meanings in different cultures. The owl is a nocturnal raptor with huge eyes, a facial disc, a hooked beak, and a loud hooting sound. In Bible, an owl is also written as a symbol of intelligence and knowledge. Bible represents an owl as an unclean bird.
