Owls Order Strigiformes are a diverse group of birds that includes over species. The Order Strigiformes is subdivided into two families, Family Strigidae typical owls and Family Tytonidae barn owls. Many owls share characteristics such as strong talons, feathered legs, soft plummage, silent flight, keen hearing and eyesight. Their eyes face forward, requiring them to turn their head to see at different angles.
Owls, unlike many birds, do not build nests and instead use nests built by other species or inhabit hollows in trees. They inhabit terrestrial habitats around the world. They hunt prey that includes mammals, other birds, reptiles, and insects.are a group of birds known for their distinct calls, nocturnal habits, and silent flight. Owls are familiar to many people because they are often depected in various ways in popular culture. For instance, owls are often among the animals we associate with Halloween. They are also a favorite character in a variety of children's stories, such as Winnie the Pooh, The Secrets of NIMH, and Harry Potter.
But widespread understanding about this unique group of birds is often quite limited. So in this article, I'd like to explore ten things we should all know about owls: The Order Strigiformes is further divided into two families, the barn owls Family Tytonidae and the typical owls Family Strigidae. Owls are a diverse group of birds, with over species of owls belonging to the Order Strigiformes.
Owls feed on a wide variety of prey including mammals, other birds, insects, and reptiles. There are even some species of owls that live in Africa and Asia that feed on birds. Owls cannot chew their prey since, like all birds, they do not have teeth. Instead, they swallow small prey whole and must tear larger prey into smaller pieces before swallowing. They later regurgitate pellets of indigestible material such as bone, fur, and feathers.
Most owls are active at night. A few species such as the pygmy owls are active in the early morning or at dusk while some such as the burrowing owl and the short eared owl are active during the day.Owls are unable to move their eyes within their sockets to a great extent, which means they must turn their entire head to see in a different direction. Because owls have forward-facing eyes, they have well-developed binocular vision.Owls have developed special feather adaptations that enable them to minimize the sound made when flapping their wings. For instance, the leading edges of their primary feathers have a stiff fringes that reduces noise while the trailing edge of their primaries have soft fringes that helps to reduce turbulence. Downy feathers cover the surfaces of the wing to further reduce sound.
