The breeding habitat of the Great Horned Owl extends almost throughout both North America and South America. Within their habitat they can take up residence in trees that include deciduous, coniferous, and mixed forests, tropical rainforests, pampas, prairie, mountainous areas, deserts, subarctic tundra, rocky coasts, mangrove swamps, and some urban areas. Though less common in the more extreme areas (i.e. the heart of the deserts, extremely dense rainforests) and missing from the high Arctic tundra, they are found in most habitats. Individuals range in length from 46 to 68 cm (18 to 27 inches) and have a wingspan of 101 to 153 cm (40 to 60.5 inches). An average Great Horned Owl is 55 cm (22 inches) long, has a wingspan of 124 cm (49 inches) and weighs about 1400 grams (3.1 lbs). Generally, the largest owls are found closer to the Polar regions and the smallest owls are found closer to the Equator. Females are larger than males. Adults have large ear tufts, a reddish, brown or gray face and a white patch on the throat. The iris is yellow, except in the race B. v. nacurutu where it is amber. The ear tufts are not actually ears, but simply tufts of feathers. The underparts are light with brown barring; the upper parts are mottled brown. The legs and feet are covered in feathers up to the talons. There are individual and regional variations in color; birds from the sub-Arctic are a washed-out, light-buff color, while those from Central America can be a dark chocolate brown. Owls also have spectacular binocular vision needed to pinpoint prey and see in the dark. Owls cannot move their eyes like we can. Therefore, their neck must be able to turn a full 270 degrees in order to see in other directions without moving its entire body. An owl's hearing is as good — if not better — than its vision. Owls have stereo hearing that allows them to find the exact location of their prey. These birds also have 500 pounds per square inch of crushing power.
