Great Horned Owl (also known as Tiger Owl or Hoot Owl)
Secondary Flight Feather (Remex)

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
Broad and rounded with a slightly asymmetrical vane; the tip is blunt rather than pointed, typical of slow-flight woodland predators.
Size
Approximately 7-9 inches (18-23 cm) in length. This matches the standard secondary feather size for an adult Great Horned Owl, which is significantly larger than those of a Screech Owl but smaller than a Great Gray Owl.
Rarity
Common. They are the most widely distributed owl in the Americas and are frequently heard, though their camouflage makes them difficult to see.

Description

This is a large, powerful owl with prominent ear tufts and yellow eyes. The feather reflects its cryptic camouflage, designed to blend into bark. The Great Horned Owl is a top-tier nocturnal predator with a wingspan of up to 5 feet.

Colour & Pattern

Mottled brown, tan, and cream-white. The pattern consists of 'bottled' or marbled barring. The light-colored patches are characteristic of the mottled under-wing or secondary plumage of the species.

Barb Structure

Pennaceous at the top with a distinctively soft, velvet-like 'fimbriae' or fringe on the leading edge to dampen sound. The base features a significant plumulaceous (downy) section for insulation.

Texture & Surface

Extremely soft and velvety to the touch. This 'softness' is a specialized adaptation for silent flight, as it breaks up airflow and prevents the whistling sound common in other birds.

Key Features

The most diagnostic feature is the 'velvet' texture on the vane surface and the specialized comb-like fringe on the outer edge, which is unique to owls.

Habitat

Highly adaptable; found in deciduous and evergreen forests, swamps, orchards, agricultural areas, and even suburban parks or deserts.

Geographic Range

Extremely widespread across North and South America, ranging from the Arctic treeline in the north to the Straits of Magellan in the south.

Ecological Role

Apex nocturnal predator. They control populations of rodents, rabbits, and even other birds of prey. They are vital for maintaining the balance of local ecosystems.

Similar Species

Barred Owl (has more distinct, regular transverse brown-and-white bars) and Long-eared Owl (smaller, thinner feathers with more orange/buff tones).

Interesting Facts

Great Horned Owls can apply up to 300 pounds per square inch of pressure with their talons, and they are one of the few animals that regularly hunt and eat skunks because they have a poor sense of smell.

Condition Notes

Good condition. The barbs are mostly intact, though some minor fraying at the tip suggests it may have been molted naturally at the end of a breeding season.
