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")[3] or the hoot owl,[4] 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.[5] 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 occupies the same ecological niche in Eurasia despite its notably larger size. The great horned owl is also compared to the red-tailed hawk (Buteo jamaicensis), with which it often shares similar habitat, prey, and nesting habits by day; thus the red-tailed hawk is something of a diurnal ecological equivalent.[6] 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.[7]
