Turkey Vulture (also known as Turkey Buzzard, Carrion Crow)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Cathartiformes, Family: Cathartidae, Genus: Cathartes, Species: C. aura
Family: Cathartidae (New World Vultures)
- Shape
- Highly asymmetrical with a distinctively narrow leading (outer) vane and a broad trailing (inner) vane. The tip is somewhat rounded but shows significant emargination (notching) characteristic of soaring birds.
- Size
- Estimated at 12-14 inches (30-35 cm) in length. This is consistent with the primary feathers of an adult Turkey Vulture, which have wingspans reaching up to 72 inches.
- Rarity
- Common. They are among the most widespread and frequently observed large raptors in the Americas.

Description
This is a large, sturdy flight feather from a Turkey Vulture. The bird itself is a large soaring scavenger with dark plumage, a featherless red head (in adults), and a distinctive 'V' shaped (dihedral) flight profile. They are masters of thermals, rarely flapping their wings once aloft.
Colour & Pattern
Uniformly dark brownish-black to charcoal on the dorsal (upper) surface. The ventral (underside) typically shows a lighter, silvery-gray sheen due to the light-reflecting structure of the barbs. The rachis is dark near the vane but pales toward the base.
Barb Structure
Densely interlocked pennaceous barbs on the main vane for aerodynamic integrity, transitioning to a small, fluffy plumulaceous (downy) section at the very base near the calamus.
Texture & Surface
Matte finish on the dorsal side, slightly oily/water-repellent. The vane is stiff and rigid to withstand the pressures of soaring, while the barbules provide a smooth, somewhat silky feel when stroked.
Key Features
Large size, dark brownish-black coloration, extreme asymmetry of the vanes, and the distinct silvery-gray sheen seen on the underside of the barbs.
Habitat
Found in a wide variety of open and semi-open areas, including subtropical forests, shrublands, pastures, and deserts. They frequent roadsides where roadkill is common.
Geographic Range
Extensive range from southern Canada to the southernmost tip of South America. Northern populations are migratory, wintering in the southern US and Central America.
Ecological Role
Essential scavengers (nature's cleanup crew). They remove carcasses from the environment, which helps prevent the spread of diseases like anthrax and rabies. Population status is stable.
Similar Species
Black Vulture (feathers are shorter and more squared), Juvenile Bald Eagle (feathers are larger and often show mottled white patches), Common Raven (feathers are smaller and glossier black).
Interesting Facts
Unlike most birds, Turkey Vultures have a highly developed sense of smell, allowing them to locate carrion hidden under forest canopies. They also practice urohidrosis—defecating on their legs to cool down via evaporation.
Condition Notes
Fair to Good. There is significant 'zipper' separation (splits) between the barbs, likely due to wear or the feather being molted and weathered on the ground. The calamus appears intact.
