Owls

The Strigiformes (Owls) are an order of birds of prey, comprising 200 extant species. Owls mostly hunt small mammals, insects, and other birds, though a few species specialize in hunting fish. Most are solitary, and nocturnal, with some exceptions (e.g. the Burrowing Owl). They are found in all regions of the Earth except Antarctica, most of Greenland, and some remote islands. Some, like the Snowy Owl, even inhabit some of the harshest environments on Earth, such as the Artic Circle.

The living owls are divided into two families, the typical owls, Strigidae, and the barn-owls, Tytonidae. Owls have been a feature of falconry for years. In recent years, many owls have moved from their previous rural habitats to start to inhabit urban areas. The Tawny Owl has been a common visitor to cities across the UK for about forty years, where it survives on a diet of pigeons and small birds. Owls in urban areas are also known to prey on new-born kittens.
