Turkey Vulture (also known as the Turkey Buzzard or Carrion Crow in some regions)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Cathartiformes, Family: Cathartidae, Genus: Cathartes, Species: Cathartes aura · Cathartidae (New World Vultures) · Secondary flight feather (Remige), likely from the mid-wing section

Species
Cathartes aura (High confidence based on size, color, silver sheen, and rachis thickness)
Feather Type
Secondary flight feather (Remige), likely from the mid-wing section
Family
Cathartidae (New World Vultures)
Shape
Relatively broad and elongated with a slightly rounded tip. It demonstrates moderate asymmetry between the leading and trailing vanes, characteristic of secondary feathers which prioritize lift over the aerodynamics of primary feathers.
Size
Estimated at 10 to 12 inches (25-30 cm). This is consistent with the secondary flight feathers of an adult Turkey Vulture, which typically fall within this range depending on the specific position in the wing.
Rarity
Very Common. They are among the most frequently sighted large birds of prey in North America due to their soaring habits and scavenging nature.
Color & Pattern
Uniform dark charcoal grey to brownish-black on the dorsal surface. The ventral side (visible) shows a characteristic silvery-grey or 'frosted' sheen typical of vulture flight feathers. The rachis is a strikingly ivory/cream color which contrasts sharply with the dark vanes.
Barb Structure
Tightly interlocked and pennaceous throughout the main vane, providing a wind-resistant surface. The base shows a small amount of plumulaceous (downy) structure near the calamus for insulation. The barbs are mostly intact but show some separation near the edges.
Texture & Surface
The surface is matte with a slightly oily feel, characteristic of water-resistant feathers. The vane is stiff and rigid to withstand the pressures of soaring and thermal gliding. The underside has a silky, reflective texture.
Description
This is a large, sturdy flight feather from a bird built for efficient soaring. The Turkey Vulture is a large raptor with a wingspan of up to 6 feet. In flight, they are easily identified by their 'dihedral' (V-shaped) wing position and their wobbly soaring style. They have featherless red heads (in adults), which is an adaptation for hygiene when feeding on carrion.
Key Features
The most diagnostic features are the large size, the starkly pale/ivory rachis, and the distinctive silvery sheen on the underside of the dark grey vane.
Habitat
Extremely versatile; found in open country, subtropical forests, shrublands, deserts, and foothills. They are frequently seen near roadsides and landfills where carrion is present, and they roost in large groups in tall trees or on cliffs.
Geographic Range
One of the most widespread birds in the Americas, ranging from southern Canada to the southernmost tip of South America (Tierra del Fuego). Northern populations are highly migratory, often traveling in massive 'kettles'.
Condition Notes
Good condition. There is minimal 'fraying' at the edges, suggesting it was naturally molted rather than lost during a struggle. No significant fault bars are visible, indicating the bird had a consistent food supply during the feather's growth.
Interesting Facts
Unlike most birds, Turkey Vultures have an incredibly keen sense of smell, allowing them to locate carcasses hidden under dense forest canopies. They also practice 'urohidrosis'—defecating on their own legs to cool down through evaporation.
Ecological Role
They are the 'clean-up crew' of the ecosystem. By consuming carrion, they prevent the spread of diseases such as anthrax, botulism, and rabies. Their stomach acid is highly corrosive, allowing them to digest bacteria that would kill other scavengers.
Similar Species
Black Vulture feathers are shorter and darker without the pronounced silver sheen. Bald Eagle feathers are larger and lack the ivory-colored rachis. Common Raven feathers are smaller and have a much glossier, iridescent black appearance.
