20+ Owl Facts: That Will Leave You Hooting for More!

Owls are a unique category of birds known for their nocturnal behavior and hunting abilities, although some species have been observed to deviate from this characteristic.

There are more than two hundred species of owls, and they are exceptionally habitable and found in various environments. Owls are dimorphic, and their diet consists mainly of small mammals and rodents, making them helpful in protecting agricultural fields.

Owl Facts

Owls are raptors, meaning they use sharp talons and curved bills for hunting and eating other animals. Unlike hawks and eagles, most owls have huge heads, stocky bodies, and soft feathers.

Owls have forward-facing eyes and are mostly active at night. There are about 250 owl species worldwide, living on every continent except Antarctica. They belong to the Strigiformes group and are divided into two families:

Tytonidae, which includes Barn Owls, and Strigidae, which includes all other owls. Many owls produce low-frequency vocalizations that can travel long distances. Knowing these sounds can help identify owl species.

Female Owls Excel in Hunting and Reproduction:

Female owls generally tend to be larger and stronger than their male counterparts, which helps them capture and kill prey more effectively.

The breeding season is the only time of the year when owls reproduce, during which each female lays around three to four eggs.

Exploring the World of Owls:


Owls are a group of birds belonging to the Strigiformes order and are known for their nocturnal and solitary habits.

With over 200 species of owls, these birds have a broad distribution across the globe. Owls have several distinct features, including an upright stance, a large and broad head, binocular vision, binaural hearing, and specialized feathers that facilitate silent flight.

Understanding the Differences Between Male and Female Owls:

Most bird species have distinguishable differences in appearance between males and females. However, male and female owls of a particular species typically look similar.

Additionally, the smaller owl species tend to have males and females of similar size. On the other hand, in larger owl species like the great horned owl, females are up to 25 percent larger than males.

This difference in size could aid in egg incubation or allow females to protect their nests from aggressive males. Different owl species vary in size and shape, which helps them effectively hunt their preferred prey and adapt to their environment.

Superior Night Sight and Remarkable Head Rotation:

Owls Night Vision

Owls are known for their exceptional night vision. They possess large pupils and corneas that can effectively gather light. Owls can also see in bright sunlight but cannot see and interpret a broad spectrum of colors. The size of owl eyes is quite remarkable in proportion to their heads. 

Despite their excellent visual acuity, owl eyes are more flat than spherical, and this adaptation limits their ability to move their eyes. Thus, owls turn their heads to see, which they can do remarkably well, with a range of head rotation of up to 270 degrees.

The Remarkable Hearing of Owls:

Owls possess highly sensitive ears, with some species capable of hearing up to 10 times better than humans.

This acute hearing is essential for locating prey that may not be visible to their sharp eyesight. The asymmetrical alignment of owl ears is unique among animals, enabling them to pinpoint the exact location of even the faintest sounds. 

When an owl detects a sound of interest, it turns its head in different directions until it accurately identifies the source. The elliptical shape of an owl’s face functions like a satellite dish, directing sound waves to the ears.

Powerful Talons and Gripping Feat:

Owls Feat

Owls can capture their prey using their strong feet and sharp talons, which have evolved to penetrate tough animal hides and support heavy weights without breaking. Their feet are built to endure the impact of high-speed strikes and snatching. 

Most owl species have feathers on the top surface of their feet to provide insulation from the cold, while the soles of their feet are knobby and rough to enhance their grip. Additionally, these soles have extra blood vessels to dissipate excess heat. Owls have one of the strongest grip strengths of all raptors.

Unique Feather Adaptations of Owls:

Owls have two types of feathers, contour and down feathers. The contour feathers form the outer layer for protection and flight, and the down feathers provide insulation as the inner layer. Owls have fewer down feathers and rely on special barbules on their contour feathers. These feathers enable owls to withstand extreme cold. 

Owlets initially have downy feathers, which are replaced with juvenile ones before growing their first adult flight feathers. Mature owl feathers are dull in color and provide camouflage from predators and prey. Owls can fluff or compress their feathers for self-protection.

The Hunting Habits of Owls:

Hunting Habits Of Owls

Owls are mostly nocturnal animals, but some species are diurnal or crepuscular. They spend a lot of time hunting for food, mainly consisting of small mammals like voles and mice, but can also include other creatures like frogs, lizards, snakes, fish, birds, and even skunks. 

Owls use different hunting techniques such as perch and pounce, quartering flight, hovering, or running across the ground. They often hunt close to the ground to see and hear their prey better. They also hide their food. They do this when the hunting is good to stock up.

Roosting for Owls:

After a day or night of hunting, owls return to a resting place called a roost. Typically, owls roost alone, although, during the breeding season, they may roost near a nest. However, a few species roost communally, sharing a roosting area with other species members.

The benefits of shared roosts may help owls watch for predators and mobbing songbirds, keep each other warm by huddling together, find partners during mating season, and share information about good hunting spots. The roost is often located close to areas with abundant prey, allowing owls to hunt easily and return to the roost.

The Mating Habits of Owls in Late Winter:

Mating Habits Of Owls

Late winter is the mating season for most owls. Male owls call through the afternoon and evening air to attract a female mate. The large owls hoot while the small owls toot. A female owl responds to the call of a male of the same species that interests her. 

Once a male owl gains the interest of a female, he starts performing or showing off to impress her. Mating pairs of owls spend a lot of time together, preening and cooing, which helps keep their feathers in good condition and reduces aggressive behavior.

Owl Nesting Habits and Strategies:

Owls are skilled hunters but not adept nest builders. They often use existing nests built by other birds, like hawks, crows, and magpies, or nest in tree cavities created by woodpeckers.

Some species, like the Barn Owl, nest in human-made structures like barns or silos, while others, like Burrowing Owls, nest in underground tunnels dug by other animals or themselves. 

Male owls find and establish territories, but female owls ultimately select the nest site, and the owl pair defends their home for several months.

Owl Breeding and Incubation Process:


Female owls lay one to fourteen white eggs, and the number of eggs depends on the food availability. Eggs are usually laid one to four days apart; only females incubate them. During incubation, the female owl presses her warm bare skin against the eggs to keep them warm. 

Baby owls, or owlets, hatch after 3 to 5 weeks depending on the species, and because of asynchronous hatching, there can be a significant age difference between the first and last nestlings to hatch in the same nest.

The Early Life of Owlets in the Nest:

After hatching, young owls have white downy feathers and closed eyes, but their eyes open several days later, and the feathers turn darker. The female owl broods and keeps the nestlings safe for the first few weeks.

 Male owls are the ones who hunt and bring food to the nest, while the female tears the prey into smaller pieces and feeds the young.

Nestlings compete for food; the larger and older ones may get most of it. When they can thermoregulate, the female leaves the nest to help hunt, and the nestlings make food-begging calls to their parents.

Life Cycle of Owls:

Life Cycle Of Owls

After nestlings can thermoregulate, but before they can fly, they leave the nest and hide nearby in vegetation in a period called branching or nest dispersal.

When they can fly, they are called fledglings. Different owl species develop at different rates, with Short-eared owlets developing the fastest and Barn Owls and Great Horned Owls taking longer.

By autumn, most parents are done raising their young, and the fledglings are now full-sized owls ready to live independently. Although owls can live up to 25 years, most species probably have a lower average lifespan.

Owls Face Different Types of Threats Throughout Their Lives:

Adult owls are at the top of the food chain but may be attacked by eagles or other large owls. Owlets are more vulnerable to predators such as snakes, squirrels, possums, and ravens and are also affected by human interference, which can cause chick mortality. 

Young adult owls are also vulnerable due to their lack of hunting experience and may die before their first birthday. The odds of survival increase with experience and size.

Owls Are Affected by Various Parasites and Diseases:

Owls can suffer from feather lice, which can cause discomfort and health issues. Parasitic worms can also infect owls.

Although fleas and flies bother owls, they are attracted to the decaying matter in owl nests. Hepatosplentitisinfectiosastrigum is a fatal virus for many owl species, but some, like barn owls, have developed immunity to it. 

Owls are also vulnerable to pneumonia, tuberculosis, and a parasitic protozoan carried by pigeons that can cause a fatal blockage in their throats.
