Great Horned Owl (also known as Tiger Owl or Hoot Owl)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Strigiformes, Family: Strigidae, Genus: Bubo, Species: Bubo virginianus
Family: Strigidae (Typical Owls)
- Shape
- Broadly spatulate and rounded at the tip. The overall outline is soft and oval-like with a highly symmetrical vane typical of body plumage rather than flight feathers.
- Size
- Estimated at 3-4 inches (7.5-10 cm) in length. This is consistent with the larger body contour feathers of a Great Horned Owl, which provide significant insulation and volume.
- Rarity
- Common; although they are nocturnal and secretive, they are widespread and adaptable to human environments.

Description
This feather belongs to a large, powerful raptor known as the 'Great Horned Owl.' These birds are famous for the tufts of feathers on their heads (called plumicorns) that look like horns. They have a massive wingspan (up to 5 feet) and striking yellow eyes. The feather itself is designed for the owl's lifestyle as a silent nocturnal predator; its soft surface mutes the sound of air moving over the bird during flight.
Colour & Pattern
Pale cream to white base coloration with bold, dark brown to charcoal horizontal bars (banding). The bands are relatively crisp but have soft edges. There is a slight warmth or buff tone toward the lower downy section.
Barb Structure
A mix of plumulaceous (downy) and pennaceous (firm) structures. The base is heavily plumulaceous for insulation, while the tip maintains a loose pennaceous structure. Features the characteristic soft 'fringing' or velvet-like pile that reduces air turbulence for silent flight.
Texture & Surface
Extremely soft, silky, and velvet-like. It lacks the stiff, glossy waterproof coating of many other birds, instead feeling like fine down or soft fabric to the touch.
Key Features
Distinct horizontal 'tiger-stripe' banding, extremely soft/velvety texture, and a high proportion of downy fluff at the base.
Habitat
Found in an incredibly diverse range of habitats including deciduous and evergreen forests, swamps, deserts, tundra edges, orchards, and urban parks with sufficient tree cover.
Geographic Range
Year-round resident across most of North and South America, ranging from the tree line in the Arctic to the southern tip of South America. It is the most widely distributed owl in the Americas.
Ecological Role
Top-tier apex predator that controls populations of rodents, rabbits, and even other birds of prey. They are highly adaptable and serve as an indicator of ecosystem health in varied landscapes.
Similar Species
Barred Owl (Strix varia) feathers have broader, more blurred bands. Long-eared Owl (Asio otus) feathers are smaller and often have finer, more intricate mottling rather than clean horizontal bars.
Interesting Facts
Great Horned Owls can apply up to 300 pounds per square inch of pressure with their talons. They are one of the few predators that regularly hunt and eat skunks because they have a very poor sense of smell.
Condition Notes
Fair to Good. The feather shows significant 'frazzling' where the barbs have separated, likely due to exposure to the elements or physical wear before being found. There is no evidence of parasite damage, but it appears to be a naturally molted feather.
