Types of Owls
Introduction to Types of Owls
Owls are fascinating birds of prey that are found all over the world. They belong to the order Strigiformes and are divided into two families: the true (or typical) owl family, Strigidae, and the barn-owl family, Tytonidae. There are approximately 225 species of owls worldwide, with 19 species found in the United States alone.
Owls are known for their nocturnal habits and exceptional hunting skills. They have keen eyesight and hearing, which allows them to hunt in complete darkness. They are also able to fly silently, thanks to their specialized feathers that muffle sound. Owls are carnivorous and feed on a variety of prey, including small mammals, birds, and insects. Some species of owls, like the Snowy Owl, are able to catch fish.
Owls come in a variety of shapes and sizes. The smallest owl in North America is the Elf Owl, which is only about 5 inches tall and weighs less than 2 ounces. The largest owl in North America is the Great Gray Owl, which can grow up to 32 inches tall and weigh up to 5 pounds. Owls have distinctive facial features, including large eyes and a hooked beak. Their eyes are forward-facing, which gives them binocular vision and excellent depth perception.
Owls are also known for their haunting calls, which can be heard at night. Each species of owl has a unique call, which is used for communication and territorial purposes. Some types of owls, like the Barn Owl, are known for their heart-shaped facial disc, which helps them to hear prey in complete darkness.
Physical Characteristics of Owls
Owls are known for their unique physical characteristics that make them stand out from other birds. Here are some of the most notable physical features of owls:
Eyes
One of the most striking features of owls is their large, forward-facing eyes. Owls have binocular vision, which means that their eyes work together to create a single, three-dimensional image. This allows owls to accurately judge distances and accurately locate prey, even in low light conditions.
Beak
Owls have a hooked beak that is used to tear apart prey. The beak is strong and sharp, allowing owls to easily break through the tough skin and bones of their prey.
Feathers
Owls have soft, fluffy feathers that help them to fly silently through the air. The feathers also help to keep owls warm, as they are able to trap air and insulate the bird’s body.
Wings
Owls have large, broad wings that allow them to fly silently through the air. The wings are designed to create a downward force that helps to keep the bird aloft, even in strong winds.
Talons
Owls have sharp talons that are used to catch and hold onto prey. The talons are strong and powerful, allowing owls to easily catch and kill prey that is much larger than themselves.
Types of Owls by Habitat and Distribution
Owls are found all over the world, except for Antarctica. They are known to inhabit a wide range of habitats, from forests to deserts, and from the Arctic to the tropics. In this section, we will explore the different habitats and distributions of these types of owls.
Forest Owls
Forests are the most common habitats of owls. They are home to a variety of owl species, including the Barred Owl, Great Horned Owl, and the Northern Saw-whet Owl. Forest owls are found in both deciduous and coniferous forests, and they prefer to nest in tree cavities, hollow logs, and abandoned nests of other birds.
Desert Owls
Owls are also found in arid and semi-arid regions of the world, such as deserts and scrublands. The Burrowing Owl is a common species found in these regions. They are known to nest in burrows dug into the ground, and they feed on insects and small rodents.
Arctic Owls
The Arctic is home to a few species of owls, including the Snowy Owl and the Short-eared Owl. These owls are adapted to the harsh conditions of the Arctic, and they are known to breed on the tundra during the summer months. They feed on a variety of prey, including lemmings, voles, and other small mammals.
Tropical Owls
Tropical regions of the world are home to a diverse range of owl species, including the Spectacled Owl, the Crested Owl, and the Pygmy Owl. These owls are found in rainforests, savannas, and other habitats. They feed on a variety of prey, including insects, small mammals, and birds.
Types of Owls by Behavior and Lifestyle
Owls are known for their unique behavior and lifestyle. They are solitary birds and are mostly active during the night. However, there are some species of owls that are active during the day as well. Let’s take a closer look at these types of owls.
Nocturnal Owls
Most owls are nocturnal, which means they are active during the night. They have adapted to their nocturnal lifestyle in many ways. For example, they have large eyes that are designed to gather as much light as possible, allowing them to see in the dark. They also have excellent hearing, which helps them locate prey in the dark.
Nocturnal owls are also known for their silent flight. Their wings are designed to be very quiet, allowing them to sneak up on prey without being detected. They are also able to fly very slowly, which helps them to hover over an area while they search for prey.
Diurnal Owls
While most owls are nocturnal, there are some species that are active during the day. These owls have adapted to living in well-lit environments, and they have different physical characteristics than nocturnal owls. For example, their eyes are not as large as those of nocturnal owls, and they do not have the same level of hearing.
Diurnal owls are also known for their unique hunting behavior. Instead of relying on stealth and surprise like nocturnal owls, diurnal owls are more likely to chase their prey down and catch it in flight. They are also more likely to hunt in groups, which allows them to take down larger prey.
Overall, the behavior and lifestyle of owls is fascinating and unique. Whether they are nocturnal or diurnal, these birds have adapted to their environment in amazing ways, allowing them to thrive in a wide range of habitats.
Types of Owls by Conservation Status
When it comes to the conservation status of owls, there are two main categories: endangered owls and least concern owls. Here’s a breakdown of each:
Endangered Owls
Several owl species are currently listed as endangered on the Red List of the International Union for Conservation of Nature (IUCN), due to ongoing threats to their habitats. These include:
- Congo Bay-owl
- Blakiston’s Fish Owl
- Forest Owlet
- Jamaican Owl
- Madagascar Red Owl
- Philippine Eagle-Owl
These owls face a variety of threats, including habitat loss, hunting, and climate change. Efforts are being made to protect these species and their habitats, but much more needs to be done to ensure their survival.
Least Concern Owls
The majority of owl species are currently classified as least concern on the IUCN Red List. This means that their populations are stable and not currently threatened. Some examples of least concern owl species include:
- Barn Owl
- Great Horned Owl
- Eastern Screech-Owl
- Snowy Owl
- Northern Saw-whet Owl
While these species are not currently in danger, it’s still important to monitor their populations and protect their habitats to prevent them from becoming endangered in the future.
Specific Owl Species
Barn Owls
Barn Owls are known for their heart-shaped face and beautiful white and golden-brown feathers. They are found in many parts of the world, including North America, Europe, Africa, and Asia. These owls are nocturnal hunters and feed on small mammals like rodents, shrews, and bats. They are also known to eat birds, reptiles, and insects. Barn Owls are cavity nesters and prefer to make their homes in hollow trees, barns, and abandoned buildings.
Snowy Owls
Snowy Owls are large, majestic birds with white feathers and piercing yellow eyes. They are native to the Arctic regions of North America and Eurasia and are well adapted to living in cold, snowy environments. These owls are diurnal hunters and feed on lemmings, voles, and other small mammals. They are also known to eat birds and fish. Snowy Owls are ground nesters and prefer to make their homes on the tundra.
Great Horned Owls
Great Horned Owls are one of the most common owl species in North America. They are large, with prominent ear tufts and mottled brown and white feathers. These owls are nocturnal hunters and feed on a variety of prey, including rabbits, rodents, birds, and reptiles. Great Horned Owls are adaptable nesters and will use a variety of locations, including tree cavities, abandoned nests of other birds, and even human-made structures.
Eurasian Eagle Owls
Eurasian Eagle Owls are one of the largest owl species in the world. They have distinctive ear tufts and orange eyes. These owls are found in Europe and Asia and are nocturnal hunters. They feed on a variety of prey, including hares, rabbits, and birds. Eurasian Eagle Owls are cavity nesters and prefer to make their homes in rocky crevices and cliff faces.
Screech Owls
Screech Owls are small, with distinctive ear tufts and mottled brown and white feathers. They are found in many parts of North and South America and are nocturnal hunters. They feed on a variety of prey, including insects, small mammals, and birds. Screech Owls are cavity nesters and prefer to make their homes in tree cavities.

These owls are found in the southwestern United States and Mexico and are nocturnal hunters. They feed on insects like moths and beetles. Elf Owls are cavity nesters and prefer to make their homes in saguaro cactus cavities.
Reproduction and Lifespan
Breeding Habits
Owls are known for their unique breeding habits. Most owl species are monogamous and form pairs during the breeding season. The pair bonds usually last for the duration of the breeding season, especially for migratory species. During the breeding season, male owls will search for a suitable nesting site and attract a female by calling out to her. Once the pair has formed, they will engage in courtship displays, which may include head-bobbing, wing-flapping, and vocalizations.
After mating, the female owl will lay eggs in a nest made of twigs, leaves, and other materials. The number of eggs laid varies depending on the species of owl, but most species lay between 1-6 eggs. The eggs are incubated for a period of time, which also varies depending on the species. Once the eggs hatch, the female owl will care for the young while the male brings food to the nest.
Growth and Development
The growth and development of baby owls, or owlets, is fascinating. Owlets are born naked and blind, and they rely on their parents for warmth and food. As they grow, their feathers begin to grow in, and their eyesight improves. Owlets are usually able to leave the nest and fly after about 6-8 weeks, but they may stay with their parents for several months before becoming independent.
The lifespan of owls varies depending on the species and their living conditions. In the wild, most owls have a lifespan of around 9-10 years, while some can live up to 25 years. Owls in captivity tend to live longer, with some species living up to 50 years. Factors that can affect the lifespan of owls include habitat destruction, hunting, and disease.
Diet and Hunting Techniques
Owls are skilled hunters and have adapted various hunting techniques depending on their body size and prey type. Their diet is predominantly carnivorous, and they feed on a range of animals, including insects, small mammals, birds, reptiles, amphibians, and fish.
Carnivorous Owls
Carnivorous owls are those that primarily feed on small mammals such as mice, shrews, voles, and rats. Barn owls, for example, are known to feed mainly on mice, while the eagle owl can go after larger prey like foxes and ducks. Some species of owls, such as the snowy owl, also feed on birds, while others, like the great grey owl, feed on rabbits and hares.
Insectivorous Owls
Insectivorous owls, on the other hand, feed mainly on insects such as moths, beetles, and grasshoppers. Scops and screech owls are examples of insectivorous owls that feed mostly on insects. They are known to perch on a high point and wait for prey to come within striking distance.
Owls have excellent eyesight and hearing, which helps them locate their prey even in complete darkness. They also have sharp talons and a powerful beak that allows them to capture and kill their prey with ease.
