The well-developed facial ruff that owls have adapted has shown to help with sound localization as the ruff works to funnel, trap, and focus sounds. The ruff is located around the owl’s face and acts as a reflector for sound. [19]
The northern saw-whet owl has vertically asymmetrical ears and different shapes of the ear openings. Because the sound reaches the ears at a different time and is of different intensity, the northern saw-whet owl can very precisely localize its prey. Such accurate sound localization allows it to hunt in complete darkness by hearing alone.
The map was found in the owl’s midbrain, in the lateral and anterior mesencephalicus lateralis dorsalis (MLD), a structure now referred to as the inferior colliculus. Unlike most sound-localization maps, this map was found to be two-dimensional, with units arranged spatially to represent both the vertical and horizontal location of sound.
Sound localization is a listener's ability to identify the location or origin of a detected sound in direction and distance. The sound localization mechanisms of the mammalian auditory system have been extensively studied. The auditory system uses several cues for sound source localization, including time difference and level difference (or ...
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. The feathers making up this disc can be adjusted by the bird to alter ...
An owl's talons, like those of most birds of prey, can seem massive in comparison to the body size outside of flight. The Tasmanian masked owl has some of the proportionally longest talons of any bird of prey; they appear enormous in comparison to the body when fully extended to grasp prey. [35] An owl's claws are sharp and curved.
California wildlife policymakers voted to consider listing the Western burrowing owl under the state Endangered Species Act amid rapid population declines. 'Goofy' owls that nest underground ...
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 ...
