The Anatomy of an Owl's Face An owl's flat face is also called the facial disc and it refers to how the owl's feathers are positioned on its face and frame its facial features. Their face has a concaved shape that allows sound waves coming towards the owl to be caught. The owl's ears are located on either side of its head behind the eyes. The eyes and ears are both asymmetrical ...
The facial disc is a distinctive anatomical feature found primarily in owls (order Strigiformes) and also in some other birds such as harriers, consisting of a concave arrangement of densely packed, stiff feathers that encircle the face, forming a parabolic reflector around the eyes and beak to collect and direct sound waves toward the bird's asymmetrically positioned ear openings. This ...

Barn owls have a heart-shaped facial disc that acts like a satellite dish, funneling sound straight to their ears. This gives them extraordinary hearing and allows them to hunt in complete darkness.
Key field marks: Lacking the typical facial disc of an owl, this robin-sized species is mostly brown and white with a tuftless head, speckled face, and piercing yellow eyes.
Scientists found barn owls detect sound differences of just 10 millionths of a second using asymmetric ears. Their facial disc acts like a radar dish for perfect hunting accuracy in darkness.
The facial disc helps owls direct sounds to their ears, and in many species, these discs are placed unevenly for even better sound location. Most owls have feathers that help them blend in with their surroundings.
Can you talk about that? Owl's faces are designed for sound with conical facial discs around their eyes. Along the edge of the facial disc is a facial ruff or a ring of stiff feathers that form a curved wall around their face. It has been reported that the facial ruff increases sound sensitivity by about 20 decibels.
The bay owl (Phodilus badius), also known as the Oriental bay owl, is a small nocturnal owl species in the barn owl family Tytonidae, distinguished by its heart-shaped facial disc framed by elongated, ear-like feather tufts, dark chestnut-brown upperparts with golden spotting, and pale creamy-gray underparts lightly spotted on the flanks. Measuring 23-29 cm in length with a wing length of ...
Different species of owls produce different sounds; this distribution of calls aids owls in finding mates or announcing their presence to potential competitors, and also aids ornithologists and birders in locating these birds and distinguishing species. As noted above, their facial discs help owls to funnel the sound of prey to their ears.
The facial disc essentially functions as a biological satellite dish, amplifying faint sounds made by prey animals. Owls can adjust the shape of this disc using specialized muscles, effectively "aiming" their hearing in specific directions.
Although some owls sport ear tufts, they're not ears at all, but simply display feathers that indicate an owl's mood, sort of like how a cat swivels its ears to signify how it feels. An owl's true ears are hidden at the sides of its head, behind the eyes; and they are covered by the feathers of the facial disc.
The facial disc is more rounded and less pronounced than other owls, and it features striking yellow eyes framed by bushy, white "eyebrows". The long, powerful legs are unfeathered, helping in its hunting prowess, especially around water. ️🥰🦉 #owl #owls #owlsofinstagram #owllove #wildlife #animals
For many folks, owls are spooky and mysterious creatures. But the truth is that they are some of the most fascinating of the nocturnal creatures in our world. All owls are cool, but the coolest may be Great Horned Owls.
The owl in the image is a Eurasian eagle-owl (Bubo bubo). This identification is based on its large size, prominent dark ear tufts, white eyebrows, and distinctive orange-red eyes.
With its distinctive heart-shaped facial disc, the barn owl is the bird to celebrate this holiday. The barn owl's facial disc consists of whitish feathers set in a concave pattern that directs sound toward its ears.
Along the edge of the facial disc is a facial ruff or a ring of stiff feathers that form a curved wall around their face.
Many owl species have a distinct facial disc. This acts like a "radar dish", guiding sounds into the ear openings.
Two open country foragers (snowy owl, burrowing owl) have small facial discs and symmetrical ears, but another (barn owl) has a complete facial disc and strongly asymmetrical ears.
The barn owl, Tyto alba, has a prominent heart-shaped facial disc that aids it during hunting. Other bird species, such as harriers, have less prominent facial discs. In harriers, the related term facial ruff refers to feathers around the neck that are raised in response to noise, essentially enlarging the facial disc and improving hearing.
Anatomy of Owl Facial Discs Owls have a unique feature called facial discs, which resemble a satellite dish, expertly designed to enhance their hearing capabilities. This remarkable facial disc structure acts like a natural sound amplifier, allowing owls to detect even the faintest rustle of prey in the dark.
Some Owl species have asymmetrically set ear openings (i.e. one ear is higher than the other) - in particular the strictly nocturnal species, such as the Barn Owl or the Tengmalm's (Boreal) Owl. These species have a very pronounced facial disc, which acts like a "radar dish", guiding sounds into the ear openings.
What is Facial disc? Facial disc is the concave collection of feathers on the face of some birds—most notably owl s—surrounding the eyes.
An adaptation is a characteristic that helps give an owl species its best chance at survival. Owls live in many different environments but have evolved in order to stay near the top of the food chain. Owl adaptations include feathers for silent flight, facial discs, asymmetrical ears, tufts, 270 degree head rotation
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.
While barn owls have a heart-shaped facial disc like the barred owl, their ear tufts are much smaller and not as noticeable. The light-colored plumage on their face helps direct more sound to their ears.
Owl Face Facts 1. Facial discs: Owls have round faces, also known as facial discs, which are made up of stiff feathers arranged in a circular pattern around their face. The facial discs aid in the transmission of sound to the owl's ears, which are located at the disc's edges, allowing them to locate prey accurately even in complete darkness. 2.
The Great Horned Owl is a large owl with long wings and a large head. It's one of the most common owls in North America. Great Horned Owls are large, stocky birds with soft feathers that are gray to brown on their backs and white on their chests.
Sometimes called the Phantom of the North or the Spectral Owl, the large Great Grey Owl makes a formidable impression in forests of the Northern Hemisphere. Owls are naturally able to fly and glide silently, thanks to specially structured feathers, but the Great Grey Owl has an additional advantage: the largest facial disc of any raptor.
The Barn Owl, Tyto alba, has a prominent facial disc In ornithology, the facial disc is the concave collection of feathers on the face of some birds —most notably owls —surrounding the eyes.
This unique and complex auditory system is a combination of specialised feathers forming a parabolic facial disc, adjustable operculum, or flaps and, in some species, asymmetrical ear openings. This unique system allows the owl's brain to construct an auditory map of space when locating its prey.
An owls flat face is also known as the facial disc which describes the positioning of the feathers that frame the owl's facial features. The feathers circle round the eyes and lead to the ear holes that are located asymmetrically on each side of the owl's head just behind the eyes inside the owls facial disc.
An area of very short feathers that radiate out from the eyes like the spokes of a wheel. This special feather arrangement helps send sound to the birds ears. All owls have a facial disc. Subscribe to Facial disc
Exactly where are an owl's ears? Well, the eyes of this Great Gray Owl are set in a broad, dish-shaped face. Ridges of tiny hair-like feathers rim the owl's face, creating "facial disks." Just below the margins of the facial disks, concealed by feathers, are the openings to the owl's ears.
The bone structure itself also contributes to the owl's accuracy. The shape of the skull supports the funnel-like role of the facial disc, which works as a natural sound collector. By guiding sound toward the ear openings, the skull and the feather arrangement work together to sharpen the owl's sense of direction.
The bird shown is a juvenile Barred Eagle-Owl (Bubo sumatranus), also known as the Malay Eagle-Owl. This species of owl is native to Southeast Asia and is found in dense forests, large parks, and...
The Evolutionary History of the Barn Owl's Facial Features The barn owl's facial features have evolved over millions of years to make it a highly efficient predator. The heart-shaped facial disc, asymmetrical ears, and soft feathers are all adaptations that have allowed the owl to hunt in complete darkness and silence.
Here we explore the evolution of comb and facial disc morphology. We measured leading-edge comb morphology on museum skins of 147 owl species, and facial disc morphology from photos, as well as ecological traits, on 66 species.
