Turkey Vulture (also known as Turkey Buzzard)
Kingdom: Animalia; Phylum: Chordata; Class: Aves; Order: Cathartiformes; Family: Cathartidae; Genus: Cathartes; Species: Cathartes aura · Cathartidae (New World Vultures) · Primary flight feather (specifically a 'remex'), likely P4 or P5 from the right wing
Species
Cathartes aura (100% confidence)
Feather Type
Primary flight feather (specifically a 'remex'), likely P4 or P5 from the right wing
Family
Cathartidae (New World Vultures)
Shape
Highly asymmetrical with a significantly narrower leading edge (outer vane) and a broader trailing edge (inner vane). The tip is rounded and shows distinctive emargination (notching) which reduces drag during soaring.
Size
Approximately 12 to 14 inches long. This size is consistent with an adult Turkey Vulture's mid-primaries, which typically range from 30cm to 40cm in length.
Rarity
Very Common. It is one of the most widespread and frequently observed raptors in the Western Hemisphere.
Color & Pattern
Dorsally dark brownish-black to charcoal. Ventrally, the feather appears lighter gray-silver due to the structure of the barbs reflecting light, which creates the 'two-toned' wing appearance characteristic of the species in flight. No banding or spots are present.
Barb Structure
Pennaceous and tightly interlocked in the main vane for aerodynamic integrity. The base/calamus area shows plumulaceous (downy) barbs for insulation. The barbs are stiff and durable to withstand the stresses of soaring.
Texture & Surface
Relatively stiff and coarse with a matte finish. It lacks the oily sheen found in waterfowl but is highly resistant to wind damage. The trailing edge is smooth, while the leading edge is rigid.
Description
This is a large, dark flight feather from a Turkey Vulture. The bird itself is a large soaring scavenger with a 6-foot wingspan, identifiable by its red featherless head and 'V-shaped' (dihedral) flight profile. In the air, they are masters of thermals, rarely flapping their wings.
Key Features
Total lack of banding, silvery-gray underside contrast, prominent pale-colored rachis, and the large size combined with deep emargination at the tip.
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
Widespread across 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.
Condition Notes
Good condition. There is slight fraying at the tip and some separation of the barbs (zips) near the base, likely due to contact with the ground or handling, but no significant parasite damage (fault bars) is visible.
Interesting Facts
Turkey Vultures have one of the most acute senses of smell in the entire bird world, allowing them to find carrion hidden under forest canopies. They also practice urohidrosis—defecating on their own legs to cool down via evaporation.
Ecological Role
Primary scavenger (detritivore). They serve as 'nature's cleanup crew,' removing carcasses that could otherwise spread diseases like anthrax or rabies, as their stomach acid is potent enough to neutralize these pathogens.
