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 feathers (Remiges); specifically outer primaries likely P8-P10 given the strong asymmetry.
Species
Cathartes aura (100% confidence)
Feather Type
Primary flight feathers (Remiges); specifically outer primaries likely P8-P10 given the strong asymmetry.
Family
Cathartidae (New World Vultures)
Shape
Highly asymmetrical with a very narrow leading edge (outer vane) and a wide trailing edge (inner vane). The tips are rounded but tapered.
Size
Estimated at 12-16 inches (30-40 cm) in length. This is consistent with the large wing span of the Turkey Vulture (typically 63-72 inches).
Rarity
Very Common; one of the most widely distributed and frequently seen large birds in the Americas.
Color & Pattern
Uniform dark brownish-black to charcoal grey on the dorsal side, appearing lighter silvery-grey on the ventral (underside). The rachis is distinctively pale/whitish, which is a key diagnostic feature for this species.
Barb Structure
Densely packed pennaceous barbs designed for aerodynamic lift; the leading edge is extremely stiff while the trailing edge is more flexible. Fair condition with some separation (zippering) visible on the right specimen.
Texture & Surface
Relatively stiff and matte. The surface lacks the softness of an owl feather, instead being oily and durable to withstand long periods of soaring.
Description
These feathers belong to a large soaring bird with dark plumage and a bald red head. In flight, Turkey Vultures hold their wings in a slight 'V' shape (dihedral) and teeter unsteadily. Their feathers are evolutionarily adapted for effortless soaring over long distances while searching for carcasses using their keen sense of smell.
Key Features
Large size, dramatic asymmetry of the vane, uniform dark coloration, and most importantly, the stark white/pale rachis (central shaft).
Habitat
Open and semi-open areas, including subtropical forests, shrublands, pastures, and deserts. They are commonly found near roadsides and landfills where carrion is present.
Geographic Range
Extremely wide range from southern Canada to the southernmost tip of South America. Northern populations are migratory.
Condition Notes
Good to Fair. The feather on the right shows significant 'unzipping' of the barbs (loss of barbule hook engagement), likely due to mechanical wear or handling after being found.
Interesting Facts
Turkey Vultures are one of the few birds with a highly developed sense of smell, allowing them to find carrion hidden under forest canopies. They also practice urohidrosis, cooling themselves by urinating on their own legs.
Ecological Role
Primary scavengers; they play a critical role in 'cleaning' the environment by removing carcasses, which prevents the spread of diseases like anthrax and rabies.
