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 very narrow, stiff leading vane and a broad trailing vane. The tip is tapered and shows significant emargination (notching) which reduces drag during soaring.
- Size
- Approximately 12 to 14 inches in length. This is consistent with the large wingspan of a Turkey Vulture, where outer primaries typically range from 30 to 40 centimeters.
- Rarity
- Common; one of the most widely distributed and frequently observed large birds of prey in North America.

Description
This is a large, dark flight feather from a soaring specialist. The Turkey Vulture is a large bird with a 5-6 foot wingspan, distinguished in flight by its 'V' shaped dihedral wing position and unsteady rocking motion. Adults have a featherless red head, while juveniles have greyish-black heads. Their plumage is almost entirely dark, providing a stark contrast to the silvery-grey flight feathers seen from below.
Colour & Pattern
Uniform dark brown to charcoal black on the dorsal surface. The ventral (underside) surface typically appears silvery-grey in reflectant light. The rachis is pale, transitioning from a creamy white at the base to a darker shade toward the tip.
Barb Structure
Densely pennaceous and interlocked for aerodynamic integrity. The trailing edge shows some separation of barbs (fraying), indicating a naturally worn state common in large soaring birds. The base near the calamus shows a small amount of plumulaceous (downy) structure.
Texture & Surface
Stiff and somewhat coarse to the touch. The surface is matte rather than glossy, which is typical for vultures. The leading edge is extremely rigid to withstand high air pressure during flight.
Key Features
Large size, dark brownish-black coloration, ivory-colored rachis, and the distinct 'notched' or emarginated shape of the outer vane characteristic of New World Vultures.
Habitat
Found in a wide variety of open and semi-open areas, including subtropical forests, shrublands, pastures, and deserts. They frequent roadsides where carrion is present.
Geographic Range
Extremely widespread throughout the Americas, ranging from southern Canada to the southernmost tip of South America. Northern populations are migratory, wintering in the southern US and further south.
Ecological Role
Vital 'sanitation workers' of the ecosystem. By consuming carrion, they help prevent the spread of diseases such as anthrax, tuberculosis, and rabies that might otherwise persist in rotting carcasses.
Similar Species
Black Vulture feathers are shorter and lacks the silvery-grey underside; Golden Eagle feathers are larger and often show mottled 'base coloring' or banding in younger birds; Common Raven feathers are smaller and glossier with a dark rachis.
Interesting Facts
Turkey Vultures are among the few birds with a highly developed sense of smell, allowing them to locate carrion hidden under forest canopies. They also practice urohidrosis, where they defecate on their own legs to cool down through evaporation.
Condition Notes
Fair to Good. There is noticeable wear and 'zipper' separation of the barbs along the trailing edge, and the tip shows some minor breakage, suggesting this was a naturally molted feather at the end of its life cycle.
