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
- Highly asymmetrical with a narrow leading edge (outer vane) and a wide trailing edge (inner vane). The tip is rounded, and the overall profile is elongated and slightly curved.
- Size
- Estimated at 10-12 inches (25-30 cm) in length. This is consistent with the primary feathers of a large female Great Horned Owl, which generally possess larger dimensions than males.
- Rarity
- Common. Among the most widespread and adaptable owls in the Americas, though they are nocturnal and more often heard than seen.

Description
This feather belongs to the Great Horned Owl, a powerful apex predator with a wingspan up to 4.8 feet. The bird features prominent ear tufts (plumicorns), a white throat patch, and a variegated gray-brown plumage that provides perfect camouflage against tree bark.
Colour & Pattern
Base color is a creamy buff/tan with dark brownish-black horizontal barring. The bars are spaced unevenly and appear slightly mottled. The ventral side is noticeably paler than the dorsal side.
Barb Structure
Pennaceous and tightly interlocked throughout most of the vane. A diagnostic feature is the velvet-like pile (fimbriae) on the dorsal surface and the frayed, comb-like leading edge (serrations) which reduce air turbulence.
Texture & Surface
Extremely soft and velvety to the touch. The surface has a matte finish due to the microscopic hair-like structures that break up sound waves, enabling silent flight.
Key Features
Soft velvety texture, distinct dark horizontal barring on a buff background, and the presence of silent-flight serrations on the leading edge of the outer vane.
Habitat
Found in an incredibly diverse range of habitats including deciduous and evergreen forests, swamps, deserts, subalpine fields, and urban parks/orchards.
Geographic Range
Extremely widespread resident across North and South America, ranging from the subarctic tree line in Alaska and Canada south to the tip of South America.
Ecological Role
Top-tier predator that controls rodent, rabbit, and even other raptor populations. They are ecological indicators of a healthy, diverse food web.
Similar Species
Long-eared Owl feathers are similar but much smaller and more slender. Snowy Owl feathers are primarily white with dark spotting. Barred Owl feathers have more regular, chocolate-brown banding and lack the deep buff base tone.
Interesting Facts
Great Horned Owls have a grip strength of up to 500 PSI, which is comparable to that of a Golden Eagle. They are one of the few animals that regularly prey on skunks, as they have a very poor sense of smell.
Condition Notes
Good condition. There is some minor separation of the barbs at the base and tip, but the rachis is intact and the pigmentation remains vibrant without significant sun bleaching.
