Asio flammeus, commonly known as the Short-eared Owl, is a medium-sized owl found in open country and grasslands across the world. It has distinctive short ear tufts, a round face with yellow eyes, and mottled brown plumage. Known for its daytime hunting, it preys on small mammals and birds.

Asio flammeus, commonly known as the Short-eared Owl, is found in a wide range of geographical locations. Its native region encompasses much of North America, South America, Europe, Asia, and some parts of Africa. It is notably present in the United States, Canada, the British Isles, Scandinavia, Russia, Japan, and parts of South America such as Argentina and Chile. Additionally, it is found in regions of Central and Eastern Africa.

The Short-eared Owl typically inhabits open country environments such as grasslands, marshes, and tundra. It prefers areas with low vegetation that allow for easy hunting of its prey, which primarily consists of small mammals and occasionally birds. The species is also found in agricultural fields, especially during winter when it may migrate to more temperate areas.

Asio flammeus occupies an ecological niche as a predator of small mammals and birds, contributing to the control of these populations in its habitat. It is adapted to a variety of open landscapes, which makes it a versatile species capable of surviving in diverse conditions ranging from temperate to subarctic climates. Its ability to fly silently and its acute hearing make it an effective night and crepuscular hunter.
