Great Horned Owl
January 12, 2012 by staff
Great Horned Owl, Great Horned Owls range in length from 18-27 in (46-69 cm) and have a wingspan of 40-60.5 in (101-153 cm); Females are larger than males, an average adult being 22 in (55 cm) long with a 49 in (124 cm) wingspan and weighing about 3.1 lbs (1400 g). Depending on subspecies, Great Horned Owls can weigh from 0.72 to 2.55 kg (1.6 to 5.6 lb).
Adults have large ear tufts, a reddish, brown or gray face and a white patch on the throat. The iris is yellow, except the amber-eyed South American Great Horned Owl (B. V. nacurutu). Its “horns” are neither ears nor horns, 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.
Their call is a low-pitched but loud ho-ho-hoo hoo hoo; sometimes it is only four syllables instead of five. The female’s call is higher and rises in pitch at the end of the call. Young owls make hissing or screeching sounds that are often confused with the calls of Barn Owls.
Great Horned Owls can be easily confused with the Magellanic Horned Owl (B. magellanicus) and other eagle-owls. They are all generally allopatric though.
