Turkey Vulture
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Cathartiformes, Family: Cathartidae, Genus: Cathartes, Species: aura · Cathartidae (New World Vultures) · Primary flight feather (Remex). Specifically likely an outer primary (P6-P9) due to the strong asymmetry.
Species
Cathartes aura
Feather Type
Primary flight feather (Remex). Specifically likely an outer primary (P6-P9) due to the strong asymmetry.
Family
Cathartidae (New World Vultures)
Shape
Highly asymmetrical with a very narrow leading edge (outer vane) and a broad trailing edge (inner vane). The tip is tapered and shows distinct emargination on the inner vane, characteristic of soaring birds.
Size
Estimated between 12 to 15 inches (30–38 cm). This matches the typical range for the outer primaries of an adult Turkey Vulture.
Rarity
Very Common. One of the most widespread and frequently observed raptors in the Western Hemisphere.
Color & Pattern
Two-toned coloration. The dorsal (upper) surface is a deep brownish-black to charcoal black. The ventral (under) surface appears lighter and more silvery-gray due to the reflective nature of the barbs, which creates the distinctive 'silver wing linings' seen in flight.
Barb Structure
Pennaceous; tightly interlocked and rigid to withstand the aerodynamic forces of flight. The base shows a small amount of plumulaceous (fluffy) down for insulation.
Texture & Surface
The surface is matte with a slightly waxy or oily feel, providing weather resistance. The leading edge is very stiff and sharp, while the trailing edge is softer.
Description
Large soaring bird with a wingspan of up to 6 feet. They are characterized by their naked red heads (in adults) and dark plumage. In the air, they are easily identified by their 'dihedral' (V-shape) wing position and unsteady, rocking flight style.
Key Features
Large size, dramatic asymmetry of the vanes, and the distinct contrast between the dark upper surface and the lighter, silvery underside of the flight feather.
Habitat
Found in a vast variety of open and semi-open areas, including subtropical forests, shrublands, pastures, and deserts. They frequently roost in large trees or on rocky cliffs.
Geographic Range
Extremely wide range covering most of the Americas, from southern Canada to the southernmost tip of South America. Northern populations are migratory.
Condition Notes
Good condition. The vanes are mostly intact with minor 'zipping' issues at the tip. There is no evidence of heavy parasitic wear or significant sun bleaching.
Interesting Facts
Turkey Vultures have an extraordinary sense of smell, able to detect carrion from miles away. Unlike most birds, they lack a syrinx (vocal organ), so they can only produce grunts or hisses.
Ecological Role
Scavenger. They play a vital role as nature's cleanup crew, removing carcasses and preventing the spread of diseases like anthrax and rabies.
