The Strigidae, typical owls, include all the living owls except the barn and grass owls. Members of this family have a round facial disc and relatively larger eyes than the barn owls, and lack a grooming claw on the middle toe.
Historically, the typical owls have been divided between two subfamilies. The Striginae were characterised by a well-defined facial disc, and ear openings at least half the height of the skull, with a marginal dermal flap and a ligamentous or muscular bridge crossing the opening. The Buboninae, in contrast, lacked a strong facial disc and had smaller, simple ear openings. Recent phylogenies, however, have not supported this division, with the ‘Striginae’ being polyphyletic within the ‘Buboninae’. Instead, the hawk-owls of the genus Ninox may diverge basally within the Strigidae; these relatively long-winged and -tailed owls are found in Asia and Australasia.
Other genera include the boreal and saw-whet owls of the genus Aegolius, small, short-tailed and broad-winged owls with well-developed facial discs found in cooler regions of the Holarctic. The northern hawk owl Surnia ulula is another Holarctic species that is unusual in being diurnal. The elf owl Micrathene whitneyi is a small, sparrow-sized owl found in southern North America.
