Owls are primarily nocturnal birds of prey that fit in one of two families: Tytonidae or barn owls with their distinct heart-shaped facial disks and Strigidae—all other owl.
Owl is a large, round head and huge, forward-facing eyes are features that make an owl instantly recognizable. All owls have an upright posture and forward-facing eyes that give them binocular vision, just like humans.
They also have a sharp, downward-facing beak (or bill), and soft, cryptically colored plumage. Males and Females are generally similar in appearance, although the female is often up to 25% larger.
The eyes of an owl are not true “eyeballs.” Their tube-shaped eyes are completely immobile, providing binocular vision which fully focuses on their prey and boosts depth perception.
Owls are raptors, which means they hunt other living things for their food, using their special adaptations and unique abilities that set them apart from any other creature.
Owls hunt throughout the night in deserted places such as cemeteries, run-down farms, and other open areas. Owls apparently feed only on animals. Rodents are the most common prey; the smaller species, however, eat insects.
Prey is usually eaten whole, but the whole prey is not digested. An owl's digestive tract compresses the undigested portions of the prey, such as fur and bone, into a compact pellet that the owl coughs up and expels through its mouth.
Most owls do not migrate, but they can be nomadic in searching for the best food sources.
