Owls belong to a group of birds called Strigiformes. That group is divided into two smaller groups, known as families. What is the rarest type of owl?
This owl is also the largest on Earth. How many types of owls are there in the US? Nineteen owl species are found in the United States. Ranging from the diminutive Elf Owl — the smallest owl on the continent — to the massive Great Gray Owl, these charismatic birds come in many shapes and sizes. What are the two main types of owls? Owls are divided into two families: the true or typical owl family, Strigidae, and the barn-owl family, Tytonidae. There are five species of owl in Britain: the British Barn owl, Tawny owl, Little owl, Short-eared owl and Long-eared owl; and all are causing some degree of concern to conservationists.
The research suggests that barn owls, with far simpler brains than humans and other primates, also group together different elements as they move in the same direction, to make sense of the world around them. The snowy owl Bubo scandiacus , also known as the polar owl, the white owl and the Arctic owl, is a large, white owl of the true owl family.
Snowy owls are native to the Arctic regions of both North America and the Palearctic, breeding mostly on the tundra. It is sometimes called the cat owl. This widespread bird of prey lives in mountains, grasslands, conifer forests, deserts, chapparals, and many other habitats in North and South America.

Our List While some owls depend on specific conditions for survival, others, like the Barn Owl , are remarkably adaptive and are found throughout much of the world. Barn Owl U. Barred Owl U. The owls can watch for mobbing songbirds and predators. They may also huddle together to keep each other warm. Shared roosts probably make it easier for owls to find partners during the mating season.
Owls may even pass along information about good hunting spots. The roost is commonly located next to good hunting grounds so owls can search for prey as soon as they leave or return to the roost. Late winter is mating time for most owls. Males begin seeking mates by calling through the afternoon and evening air. Generally, the large owls hoot and the small owls toot. The large Barred Owl hoots in a loud, low call that sounds like a question, "Who cooks for you?
Who cooks for you all? You can listen to the individual owl calls on our Owl ID pages. A female owl will listen for a call that interests her. She will only respond to calls from males of the same species. Once a male owl gains the interest of a female, he starts performing, or showing off.
He might display his feathers by fluffing them out. He might give the female gifts of food. Then he will fly up again and hang in the wind.
He may repeat this dance several times, all in an effort to impress the female. At the end of the performance, the male dives past the female into the grass. If the female follows him, the two owls may become a mating pair.
Mating owls spend a great deal of time together. This gesture is called preening. Scientists think it reduces fighting and other aggressive behavior. It also helps owls keep their feathers in good condition.
Many owl pairs stretch their necks forward toward their mates and coo, as if they enjoy the preening session. Owls are talented hunters, but nest builders they are not. Many owls take advantage of the hard work performed by other animals, instead of building their nests from scratch.
Some owls, like Great Horned Owls, use vacant nests in trees or on cliffs that were built by hawks, crows, magpies, or other birds. Many owls simply nest in holes, called cavities or hollows, in trees. These tree cavities occur naturally, but are often created by woodpeckers.
Elf Owls nest in saguaro cacti, where woodpeckers have created ready-made holes. Barn Owls typically nest in the rafters of barns, in empty buildings or silos, or in cavities along cliffs. Burrowing Owls live up to their name by nesting in underground tunnels that were dug by ground squirrels, prairie dogs, badgers, or other burrowing animals. Some Burrowing Owls use their feet and bills to dig burrows themselves.
Snowy Owls and Short-eared Owls "build" simple nests by scraping a shallow bowl on the ground. Scientists think male owls find and advertise a territory, but female owls select the actual nest sites. Together, the owl pair defends their nest. If local food supplies are low in a given year, owls may not breed there. But if enough food is available to feed a growing family, female owls lay one to fourteen roundish white eggs.
Females from different owl species lay different numbers of eggs. The number also depends on how much food is available. For example, if local vole populations are high, a female Short-eared Owl might lay as many as ten eggs. If the vole population is low, she might lay just three or four eggs, or none at all.
