Great Horned Owl Facts
Great Horned Owl
Very large “eared” owl and is the largest species in the New World. Highly variable throughout its range, from large pale birds in Northern Canada to small dark races in humid southern parts. Generally mottled grey (gray) or brown upper parts, with white to rufous under-parts and facial disk. Under-parts streaks on the chest with heavy barring below. Yellow eyes with prominent ear tufts.
Our birds are the very rare sub-species from Northern Canada and their progeny have been sent to many breeding centres throughout the world to help conserve the species.
One of the most rapacious owl species. In the breeding season, it will not hesitate in attacking predators (including humans) who stray too close to the nest site.
It is reputed to be the only owl recorded as killing a human!
Nests often in the old nest of other birds such as corvids or diurnal raptors, also in large tree hollows, cave entrances, cliff ledges or depressions on the ground. 1-3 eggs are incubated for about 30 days. Young leave the nest by 7 weeks and can fly by 3 weeks later, however they do not become independent until about 5 months old.
