What is a Great Horned Owl?

A great horned owl is a type of owl native to North and South America. It gets its name from the tufts of feathers sticking up on either side of its head, which look like horns but actually aren't. These owls are typically large in size, reaching up to 25 inches (about 63.5 cm) in length with wingspans as wide as 60 inches (roughly 152 cm). Some great horned owls might weigh as much as 5.5 pounds (about 2.5 kg). The females are often slightly larger in size than the males.

Unlike other types of owls that are occasionally seen during daylight hours, great horned owls are almost strictly nocturnal creatures. It is not uncommon to hear a great horned owl hooting just as the sun begins to come up in the morning, but that is usually the last sound it will make until dusk. They spend their nights hunting prey that might include small rodents, rabbits, and small birds. The typical great horned owl may also feast on snakes, frogs, and almost any type of fish. These owls are capable of catching prey larger than themselves, and occasionally kill cats and dogs.

Great horned owls may be found almost anywhere, including forests and open grassland. They do not normally build nests — they typically care for their young using the nests of other birds. Great horned owls usually breed during January and February and keep the same mate for the duration of their lives. Most of the time, they lay between two and five eggs. The male great horned owl shares the responsibility of sitting on the eggs with the female.

It takes roughly 30 days before the eggs hatch. The young owls are typically unable to fly until they are about 10 weeks old. When autumn arrives, the young great horned owls are usually ready to leave the nest for good. The parents of the young owls may also part ways at this time due to the solitary nature of the species, but they typically reunite again when breeding season returns. Migration does not normally occur at any time during the year unless they need to find food in other areas.

The average great horned owl may live for up to 38 years in captivity. Owls living in the wild do not usually make it past 13 years. Great horned owls are vulnerable to attacks from humans and other large birds. Their greatest threats in the animal kingdom, however, are typically other great horned owls.

The Great Horned Owl, scientifically known as Bubo virginianus, is a large bird of prey native to the Americas. It's recognized by its prominent ear tufts, which resemble horns, and its deep hooting call. This owl is a versatile predator, adept at hunting a variety of prey, and is notable for its adaptability to different habitats, from deserts to forests.

Great Horned Owls are among the largest owls in North America, with an average wingspan of 3.3 to 4.8 feet (1 to 1.5 meters) and a body length of 18 to 25 inches (45 to 63 centimeters). They typically weigh between 2 to 5.5 pounds (0.9 to 2.5 kilograms), with females being larger than males, according to the Cornell Lab of Ornithology.

Great Horned Owls are formidable predators with a diverse diet. They primarily feed on small to medium-sized mammals like rabbits, mice, and voles, but they also hunt birds, reptiles, and even other raptors. Their powerful talons allow them to take down prey several times their own weight.

Great Horned Owls have a vast range and are found throughout North and South America. They inhabit a wide array of environments, including forests, grasslands, deserts, wetlands, and urban areas. Their adaptability to different climates and terrains makes them one of the most widespread owl species.

Great Horned Owls communicate through a series of vocalizations, the most iconic being their deep, resonating hoots used for territory establishment and mate attraction. They also use a variety of other sounds, such as barks, shrieks, and coos, especially during the breeding season or when young owlets are communicating with their parents.

Great Horned Owls are currently not endangered and are listed as "Least Concern" by the International Union for Conservation of Nature (IUCN). Their widespread distribution and generalist feeding habits contribute to their stable population status. However, they still face threats from habitat destruction, rodenticides, and human disturbances.
