Turkey Vulture (also known as Turkey Buzzard)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Cathartiformes, Family: Cathartidae, Genus: Cathartes, Species: aura
Family: Cathartidae (New World Vultures)
- Shape
- Highly asymmetrical with a narrow, stiff leading vane and a broader trailing vane. The tip is somewhat rounded but appears notched due to natural emargination on the inner vane and a slight cutout on the outer vane for aerodynamic stability during soaring.
- Size
- Approximately 12 to 14 inches (30-35 cm) in length. This is consistent with the mid-to-outer primary feathers of a large soaring bird; full primary range for this species is typically 11-16 inches.
- Rarity
- Very Common. One of the most abundant large aerial birds in North America.

Description
This feather belongs to the Turkey Vulture, a large soaring bird with a wingspan of up to 6 feet. The bird is almost entirely black with a featherless red head. In flight, it is easily identified by its 'V' shaped dihedral soar and unsteady rocking motion. It is a master of thermals, rarely flapping its wings as it uses its keen sense of smell to locate carrion.
Colour & Pattern
Uniformly dark brownish-black to charcoal gray on the upper surface. The underside of the vane typically shows a lighter, silvery-gray sheen which is characteristic of the species. The coloration is melanin-rich, providing durability against wear.
Barb Structure
Tightly interlocked pennaceous structure throughout most of the vane to withstand the air pressure of soaring flight. The base shows small plumulaceous (downy) barbs for insulation. The barbs are stiff and intact with some minor fraying at the tip.
Texture & Surface
Relatively stiff and coarse compared to songbird feathers. The surface is matte rather than glossy, designed for durability during long durations of soaring flight rather than water repellency or display.
Key Features
Large size, dark brownish-black color with a lighter silvery undersurface, a very thick rachis, and a distinct notch (emargination) on the vane which is diagnostic for large soaring raptors and vultures.
Habitat
Extremely versatile: found in open country, subtropical forests, shrublands, deserts, and foothills. They are frequently seen soaring over roadsides and open fields in search of carrion.
Geographic Range
Widespread across the Americas, ranging from southern Canada to the southernmost tip of South America. Northern populations are migratory, moving to the southern US and Central/South America during winter.
Ecological Role
Scavenger. By consuming carrion, Turkey Vultures perform a vital service by removing rotting carcasses from the environment, which helps prevent the spread of diseases such as anthrax and rabies.
Similar Species
Black Vulture (shorter, broader feathers, usually darker), Juvenile Bald Eagle (often show white mottling or a different sheen), and California Condor (significantly larger and much rarer).
Interesting Facts
Unlike most birds, Turkey Vultures have a highly developed sense of smell, allowing them to find food hidden under forest canopies. They also practice urohidrosis—defecating on their own legs—to cool down through evaporation and to kill bacteria with their highly acidic waste.
Condition Notes
Good condition. The rachis is strong and the barbs are mostly zipped (interlocked). There is minor wear at the very tip and a small split in the trailing vane, likely due to natural wear or molting.
