owl : any of an order (Strigiformes) of chiefly nocturnal birds of prey with a large head and eyes, short hooked bill, strong talons, and soft fluffy often brown-mottled plumage — Webster
Owls are birds from the order Strigiformes, which includes about 200 species of mostly solitary and nocturnal birds of prey typified by an upright stance, a large, broad head, binocular vision, binaural hearing, sharp talons, and feathers adapted for silent flight. Exceptions include the diurnal northern hawk-owl and the gregarious burrowing owl. Owls hunt mostly small mammals, insects, and other birds, although a few species specialize in hunting fish. They are found in all regions of the Earth except Antarctica and some remote islands. Owls are divided into two families: the Strigidae family of true (or typical) owls; and the Tytonidae family of barn-owls. — Wikipedia

Speaking up for invisible raptors
on March 25, 2019 at 11:40 am
Birds of prey such as owls, eagles, falcons and vultures are soaring and elegant predators. But many raptors worldwide have flown under the scientific radar and are all but invisible: Ten species of raptors, out of 557 total, comprise one-third of all raptor research, and one-fifth of all species have never been studied in a scientific publication. That's the conclusion of a recent paper in Diversity and Distributions by University of Utah researchers and their collaborators. […]

To determine where a sound is coming from, animal brains analyze the minute difference in time it takes a sound to reach each ear—a cue known as interaural time difference. What happens to the cue once the signals get to the brain depends on what kind of animal is doing the hearing. […]
