Description
A large, thick-bodied owl with prominent ear tufts and striking yellow eyes. The Great Horned Owl is a nocturnal apex predator known for its deep, rhythmic hooting. Its plumage is designed for camouflage against tree bark.
Colour & Pattern
Mottled ochre and tawny-buff base with bold, dark brown transverse banding. Transitioning to a white or pale cream base towards the inner vane. Fine 'vermiculation' (salt-and-pepper speckling) on the outer vane.
Barb Structure
Pennaceous throughout most of the vane with a characteristic soft, velvet-like 'fringe' or 'fluff' on the trailing edge and dorsal surface for near-silent flight. Plumulaceous at the base.
Texture & Surface
Extremely soft, velvety, and matte. Lacks the crisp, oily 'snap' of waterfowl feathers, optimized instead for sound dampening during flight.
Key Features
Velvet texture, bold dark banding on a mottled buff background, and a characteristic soft fringe on the trailing edge.
Habitat
Highly adaptable; found in deciduous and evergreen forests, swamps, deserts, subarctic tundra, orchards, and urban parks.
Geographic Range
Resident throughout North and South America, from the tree line in the Arctic to the southern tip of South America. Non-migratory.
Ecological Role
Apex nocturnal predator; controls populations of rodents, rabbits, and even other birds of prey. Essential for maintaining balanced ecosystems.
Similar Species
Long-eared Owl (smaller, different banding density) and Barred Owl (lacks the same tawny/ochre tones, bands are more uniform).
Interesting Facts
Great Horned Owls have a crushing power in their talons of up to 500 psi. They are one of the few predators that regularly hunt skunks due to their poor sense of smell.
Condition Notes
Fair to Good; shows some separation of the barbs (zipper effect) along the trailing edge and some minor wear at the tip, likely a naturally molted specimen.
