South American great horned owls typically have a smaller white throat patch, often unseen unless actively displaying, and rarely display the white area on the chest. The white throat may continue as a streak running down the middle of the breast even when the birds are not displaying, which in particularly pale individuals can widen at the belly into a large white area. Great horned owl showing much of its camouflage pattern/colorĪ variable-sized white patch is seen on the throat. All subspecies are darkly barred to some extent along the sides, as well. 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. The great horned owl is generally colored for camouflage. 7.3 Effect on conservation-dependent species.5.7 Interspecific predatory relationships.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. 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, thus is something of a diurnal ecological equivalent. 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. It is an extremely adaptable bird with a vast range and is the most widely distributed true owl in the Americas. 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.
