The Great Horned Owl is the most widely distributed own across North and South America. Twenty subspecies have been identified. It is the heaviest owl in Central and South America and the second heaviest owl in North America. They have relatively short wings ranging in length from 300 – 400 centimetres (12 – 16 inches) which gives them a high level of maneuverability.
They prey largely on rabbits and hares but also eat a wide range of larger sized mammals as well as birds, reptiles, amphibians and invertebrates. Hunting takes place in the evening or early morning. Small prey are eaten whole while larger creatures are torn into pieces. The indigestible bones, feathers and fur is regurgitated as a pellet several hours after eating.
Great Horned Owls form pair bonds and are highly territorial. They nest in Canada as early as March or April.
