The Great Horned Owl is the largest and best known of the American "eared" owls. It feeds on a large variety of animals, including grouse, rabbits, beetles, lizards, frogs, birds (including crows), ducks, and other owls. This bird can live for more than 12 years; some captive birds have lived to 29 years old.
The genus Bubo (BEW-boh) is from the Latin word meaning "owl" or from the Greek word for "eagle owl" used by the great 1st century Roman naturalist Pliny (Gaius Plinius Secundus). Great horned owls are related to the eagle owl of Eurasia. The species name virginianus means "of Virginia", which is where the first Great Horned Owl specimen was collected. The common name "horned owl" comes from the large ear tufts.
