Most owls are nocturnal, actively hunting their prey in darkness. Several types of owl, however, are crepuscular—active during the twilight hours of dawn and dusk

owl at night

An owl has the best night vision of any animal, and its hearing is nearly as acute.

Owl can hear a mouse stepping on a twig from 23 meters (75 feet).

Every owl has two huge holes in its skull for ears, along with a facial disc that channels sound into the ear openings. Owl ears don’t look like our ears, but they are incredibly good at picking up sounds.

An owl’s eyes are enormous in relation to the size of its body.Because the owl’s eyes are so large, they have a large surface area to collect light.Specialized cells in their eyes called rod cells help these birds see in low light situations.

binocular” vision (seeing an object with both eyes at the same time).

Many species of owls have special flight feathers adapted for silent flight.Where other birds have stiff feathers that make a whooshing sound when they fly, owl feathers have soft edges that allow the birds to fly silently.This is important for owls, as they can swoop down on prey without being heard.

owl flying

Many owl species have a thick covering of feathers on their legs and feet, which protects them from snake and rat bites.

The beak of the owl is short, curved and downward-facing, and typically hooked at the tip for gripping and tearing its prey.

Owls have zygodactyl feet with two toes pointing forward and two toes pointing backward, and all their toes have sharp talons. This gives the birds a stronger, more powerful grip so they can be more effective predators.

owl nest

Number of eggs laid is from 1 to 14 eggs, depending on food supply, although 2 to 6 is the average.

Incubation period is from 15 to 35 days, depending on species.

Young owl chicks get the best of care from their mother for about three months. They are fed, protected from predators, and learn to fly and hunt so they can leave the nest and find territories of their own.
