The great horned owl is the most widely distributed true owl in the Americas. These birds range in length from 18 to 27 inches and have a wingspan of between 40 and 60 inches. Females are larger than males. Its “horns” are nothing more than large ear tufts. It has a gray, brown, or reddish face and a white patch on its throat. Larger examples of the species are found north, toward the polar regions, and smaller examples toward the Equator. It has no known predators. It has tremendous vision, able to spot prey and see in low light. Its eyes are nearly as large as those of humans. The eyes themselves do not move; the head is turned to see from side to side and is able to turn 270 degrees (75 percent of a circle).
