Turkey Vulture (also known as Turkey Buzzard, John Crow, or Carrion Crow)
Kingdom: Animalia; Phylum: Chordata; Class: Aves; Order: Cathartiformes; Family: Cathartidae; Genus: Cathartes; Species: Cathartes aura
Family: Cathartidae (New World Vultures)
- Shape
- Highly asymmetrical vane characteristic of primary flight feathers; the leading edge is very narrow and stiff, while the trailing edge is wide. The tip is tapered and slightly rounded.
- Size
- Estimated 30-38 cm (12-15 inches) in length; the long calamous (quill) and broad vane are consistent with the large wingspan of an adult Turkey Vulture.
- Rarity
- Common; one of the most widespread and frequently observed large birds of prey in North America.

Description
This is a large, dark flight feather from a Turkey Vulture, a bird recognized by its red featherless head and 6-foot wingspan. In flight, they are easily identified by their 'dihedral' (V-shaped) wing position and unsteady, rocking soaring style. They are dark brownish-black overall with silver-grey flight feathers visible from below.
Colour & Pattern
Uniform dark chocolate brown to brownish-black on the dorsal surface. The ventral (underside) appears lighter, often showing a silvery-grey sheen typical of Turkey Vultures in flight. No banding or spots present.
Barb Structure
Tightly interlocked pennaceous barbs on the majority of the vane for flight efficiency, transitioning to soft plumulaceous barbs at the base for insulation. Barbules are intact with distinct hooklets.
Texture & Surface
Relatively stiff and smooth texture. The surface has a slight matte to semi-glossy finish; it lacks the oily waterproofing of waterfowl feathers or the velvety silence-inducing fringe of owl feathers.
Key Features
Large size, asymmetrical vanes, uniform dark brown coloration without barring, and a distinct pale rachis at the base. The silvery sheen on the underside is a primary diagnostic trait.
Habitat
Extremely versatile: found in open country, subtropical forests, shrublands, deserts, and pastures. Prefers areas with high thermals for soaring and nearby forests for roosting.
Geographic Range
Common throughout the Americas, ranging from southern Canada to the southernmost tip of South America. Northern populations are migratory, moving to the southern US and Central America for winter.
Ecological Role
Scavenger; they provide a critical 'janitorial' service by consuming carrion, which prevents the spread of diseases like anthrax and rabies in the environment. IUCN status: Least Concern.
Similar Species
Black Vulture (shorter, wider feathers with white tips), Golden Eagle (typically much larger with mottled patterns), or Common Raven (shorter, more wedge-shaped tail feathers and different curvature).
Interesting Facts
Turkey Vultures have an extraordinary sense of smell, able to detect carrion from miles away. They also practice urohidrosis—defecating on their legs to cool down through evaporation and kill bacteria with their highly acidic waste.
Condition Notes
Good to Excellent condition. The vane is mostly intact with minimal fraying at the edges. No significant fault bars or signs of parasite damage are visible, suggesting a healthy molt.
