Turkey Vulture (also known as Turkey Buzzard, Carrion Crow)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Cathartiformes, Family: Cathartidae, Genus: Cathartes, Species: aura · Cathartidae (New World Vultures) · Primary flight feather (Remiges); likely middle primaries such as P5-P7.
Species
Cathartes aura
Feather Type
Primary flight feather (Remiges); likely middle primaries such as P5-P7.
Family
Cathartidae (New World Vultures)
Shape
Markedly asymmetrical with a distinct notch or emargination on the inner vane. The tip is somewhat rounded to bluntly pointed, with a broad, elongated overall outline suitable for soaring.
Size
Estimated 30-38 cm (12-15 inches) in length. This is consistent with the primary feathers of an adult vulture which typically reach these dimensions to support a large wingspan.
Rarity
Very Common. One of the most abundant large predatory birds in the Western Hemisphere.
Color & Pattern
Uniform dark brownish-black to charcoal on the upper surface (dorsal). The underside (ventral) often appears slightly paler or more silvery-gray due to the way light reflects off the barbs. No banding or spotting is present, which is diagnostic for this species.
Barb Structure
Tightly interlocked pennaceous barbs on the majority of the vane for aerodynamic integrity, transitioning to a small plumulaceous (downy) section at the base of the calamus for insulation.
Texture & Surface
Relatively stiff and coarse with a matte to slight greasy sheen. The texture is designed for durability against UV radiation and physical wear during long hours of soaring.
Description
The Turkey Vulture is a large soaring bird with a wingspan of up to 6 feet. It is characterized by its blackish plumage and naked red head in adults. In flight, it is easily identified by its 'dihedral' (V-shape) wing position and its tendency to rock unsteadily from side to side without flapping.
Key Features
Large size, uniform dark coloration, distinct asymmetry of the vanes, and the ivory-colored base of the rachis.
Habitat
Extremely versatile: found in open countryside, subtropical forests, shrublands, deserts, and foothills. Frequently seen near roadsides and landfills.
Geographic Range
Widespread throughout the Americas, from southern Canada to the southernmost tip of South America. Northern populations are migratory, wintering in the southern US and further south.
Condition Notes
The feathers show some minor wear and 'ruffling' along the edges, suggesting they may be naturally molted feathers rather than freshly grown. No significant parasitic damage is visible.
Interesting Facts
Unlike most birds, Turkey Vultures have an incredible sense of smell, allowing them to locate carrion hidden under a forest canopy from high altitudes. They also practice urohidrosis, cooling themselves by urinating on their own legs.
Ecological Role
Scavenger. They play a vital role as nature's 'clean-up crew' by consuming carrion, which helps prevent the spread of diseases like anthrax and rabies.
