How Many Species Of Owls Are There?

There are around 250 species of owls found across the world. These nocturnal birds can be found on every continent except Antarctica. Owls are classified into two main families: Tytonidae and Strigidae. While Tytonidae comprises barn owls with approximately 20 species, Strigidae, also known as true owls, consists of around 230 species.

Owls generally have a compact and rounded body shape with large, forward-facing eyes surrounded by a facial disk. Their distribution ranges from the tropical rainforests of Central and South America to the arctic tundra.

Species Classification and Distribution

Owls belong to two main families: Tytonidae and Strigidae. Strigidae consists of typical owls with a facial disk, rounded wings, and diverse global species. Tytonidae includes barn owls without a facial disk, but with broader wings for silent flight. Each family has unique traits that sets them apart:


This family includes barn owls, with around 20 species populating its ranks. Here are some owl species in the family Tytonidae along with brief descriptions of each:

  • Common Barn Owl (Tyto alba): Widespread species with a heart-shaped, pale face, light brown or grayish upperparts, and white underparts, found in open habitats.
  • Eastern Barn Owl (Tyto javanica): Asian and Australasian species resembling the Common Barn Owl, with a pale face, reddish-brown or grayish upperparts, occupying diverse habitats.
  • American Barn Owl (Tyto furcata): Native to the Americas, featuring a pale face with a heart shape, reddish-brown or grayish upperparts, and thriving in various environments.
  • Oriental Bay Owl (Phodilus badius): Southeast Asian species with a unique appearance, lacking a facial disk, and having brownish plumage, found in forests and wooded areas.


Also known as true owls, this family is much larger, comprising around 230 species. Some recognizable Strigidae members include:

  • Great Horned Owl (Bubo virginianus): Large owl with prominent ear tufts, powerful build, and distinctively deep hooting call, found throughout the Americas.
  • Northern Saw-whet Owl (Aegolius acadicus): Small owl with a round head, yellow eyes, and a high-pitched tooting call, often found in coniferous forests.
  • Long-eared Owl (Asio otus): Medium-sized owl with long ear tufts, streaked plumage, and a low hooting call, preferring woodlands and open areas.
  • Short-eared Owl (Asio flammeus): Medium-sized owl with short ear tufts, mottled brown plumage, and a raspy barking call, often found in grasslands and marshes.
  • Tawny Owl (Strix aluco): Medium-sized owl with a rounded head, reddish-brown plumage, and a characteristic hooting call, widespread in woodlands across Europe and Asia.
  • Snowy Owl (Bubo scandiacus): A large, white owl with piercing yellow eyes, a rounded head, and a distinctive appearance, known for its ability to thrive in the Arctic tundra.

The global distribution of owls is vast, covering every continent except Antarctica. They can be found in diverse habitats ranging from the tropical rainforests of Central and South America to the arctic tundra. In fact, the adaptability of these incredible birds allows them to thrive in a broad range of environments, contributing to their impressive distribution across the globe.

Owls in North America and their Conservation Status

North America is home to a wide variety of owl species, with around 19 species inhabiting the continent. Some of the most common species include the Eastern Screech Owl, Barn Owl, Great Horned Owl, and the Snowy Owl. This diverse collection of owls showcases the adaptability of these birds, as they thrive in different habitats that range from forests and grasslands to populated urban environments.

However, the conservation status of certain owl species in North America raises concerns. Species like the Northern Spotted Owl and the Burrowing Owl face challenges due to habitat loss, climate change, and human activities.

Various organizations and researchers are collaborating to implement conservation efforts aimed at addressing the challenges faced by owls. These initiatives primarily involve monitoring owl populations, preserving their natural habitats, and implementing policies to support their well-being. The ultimate goal is to protect endangered owl species and maintain the delicate ecological balance necessary for their survival.


The world of owls boasts an impressive array of approximately 250 species, belonging to the two primary families. These incredible birds showcase a vast global distribution and outstanding adaptability, being found in various habitats across continents. However, some owls face challenges from habitat loss, climate change, and human activities. As we learn about these intriguing birds, together, we can work together to address these issues and protect owls so they can continue to thrive in their natural homes and contribute to our planet’s biodiversity.
