Turkey Vulture (also known as Turkey Buzzard or TV)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Cathartiformes, Family: Cathartidae, Genus: Cathartes, Species: aura
Family: Cathartidae (New World Vultures)
- Shape
- Highly asymmetrical outer vane; elongated and tapered with a distinct emargination (notching) on the leading edge to facilitate lift and reduce turbulence during soaring.
- Size
- Approximately 12 to 14 inches (30-35 cm) in length. This is consistent with the large wingspan of an adult Turkey Vulture which ranges from 63-72 inches.
- Rarity
- Very Common. One of the most abundant large raptorial birds in the Western Hemisphere.

Description
The Turkey Vulture is a large soaring bird with a small, featherless red head and dark plumage. In the air, they are easily identified by their 'dihedral' (V-shaped) wing position and their habit of rocking unsteadily while soaring. Their feathers are designed for maximum efficiency in catching thermals, allowing them to glide for hours with minimal flapping.
Colour & Pattern
Uniform dark chocolate brown to blackish-brown on the dorsal surface. The ventral side typically shows a distinctive silvery-gray sheen on the barbs, which creates the iconic two-toned wing pattern seen in flight.
Barb Structure
Tightly interlocked pennaceous barbs on the majority of the vane for aerodynamic integrity, transitioning to a short plumulaceous (downy) section at the very base near the calamus.
Texture & Surface
Stiff and somewhat coarse texture; the vane is remarkably rigid to withstand the pressures of thermal soaring. Surface is matte rather than glossy.
Key Features
Large size, dark brown coloration, extreme asymmetry of the vane, and a distinctively pale/whitish rachis compared to the dark barbs.
Habitat
Extremely versatile: found in open country, subtropical forests, shrublands, deserts, and pastures. Often seen roosting in large trees or on rocky cliffs.
Geographic Range
Widespread across the Americas, ranging 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 scavenger; they provide a vital 'cleanup' service by consuming carcasses, which helps limit the spread of diseases like anthrax and rabies in the environment.
Similar Species
Black Vulture (feathers are shorter and more squared), Juvenile Bald Eagle (feathers lack the same consistent dark brown shade and often have white mottling), 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 locate carrion hidden under forest canopies. They also practice urohidrosis, defecating on their legs to cool down via evaporation.
Condition Notes
Good condition; the barbs are mostly intact though there is slight fraying at the tip and along the trailing edge, suggesting it was molted naturally after a season of use.
