One of the worlds most widely distributed owls, the Short-eared Owl is an open country, ground-nesting species that inhabits marshes, grasslands, and tundra throughout much of North America and Eurasia. It also breeds in South American grasslands and on islands such as Iceland, the Hawaiian chain, and the Galápagos. Few data exist for populations other than the nominate race A. f. flammeus in North America, Europe, and Asia. Most other races are considered island endemics.

Reproduction and population dynamics of this species are closely linked to the density of its primary prey, small mammals such as Microtus voles. Like other birds that depend on such a fluctuating food resource, the Short-eared Owl shows considerable local variation in its numbers and reproductive success, and is even nomadic at times. Although the literature on its diet in the nonbreeding season is extensive, few studies have thoroughly addressed other facets of its biology, ecology, and life history.
