<Tr> <Td_colspan="2"> <P> Strix virginiana Gmelin, 1788 and see text </P> </Td> </Tr> <P> Strix virginiana Gmelin, 1788 and see text </P> <P> The great horned owl (Bubo virginianus), also known as the tiger owl (originally derived from early naturalists' description as the "winged tiger" or "tiger of the air") or the hoot owl, is a large owl native to the Americas . It is an extremely adaptable bird with a vast range and is the most widely distributed true owl in the Americas . Its primary diet is rabbits and hares, rats and mice and voles, although it freely hunts any animal it can overtake, including rodents and other small mammals, larger mid-sized mammals, birds, reptiles, amphibians, and invertebrates . In ornithological study, the great horned owl is often compared to the Eurasian eagle - owl (Bubo bubo), a closely related species which, despite the latter's notably larger size, occupies the same ecological niche in Eurasia, and the red - tailed hawk (Buteo jamaicensis), with which it often shares similar habitat, prey and nesting habits by day and is thus something of a diurnal ecological equivalent . The great horned owl is one of the earliest nesting birds in North America, often laying eggs weeks or even months before other raptorial birds . </P> <P> The great horned owl is generally colored for camouflage . The underparts of the species are usually light with some brown horizontal barring; the upper parts and upper wings are generally a mottled brown usually bearing heavy, complex darker markings . All subspecies are darkly barred to some extent along the sides as well . </P>
