Turkey Vulture (also known as the Turkey Buzzard or Carrion Crow)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Cathartiformes, Family: Cathartidae, Genus: Cathartes, Species: C. aura · Cathartidae (New World Vultures) · Flight feather, specifically a primary feather from the wing (likely P4-P7)
Species
Cathartes aura
Feather Type
Flight feather, specifically a primary feather from the wing (likely P4-P7)
Family
Cathartidae (New World Vultures)
Shape
Asymmetrical vane typical of flight feathers, with a broad trailing edge and a narrower, slightly notched leading edge; the tip is somewhat rounded but shows signs of wear and minor tapering.
Size
Approximately 11-13 inches (28-33 cm). This is consistent with the primary flight feathers of a large raptor or vulture, where primaries typically range from 10 to 15 inches.
Rarity
Common. One of the most widespread and frequently observed large birds in the Americas.
Color & Pattern
Predominantly dark brownish-black to charcoal grey. The dorsal (upper) surface is darker, while the ventral (under) surface has a characteristic silvery-grey sheen or 'bloom,' which is a key identification mark for this species.
Barb Structure
Mainly pennaceous with tightly interlocked barbs for flight efficiency; the base exhibits a small amount of plumulaceous (downy) structure. The barbs are somewhat frayed at the edges due to environmental wear.
Texture & Surface
The surface is relatively matte with a slightly oily, water-repellent quality. The underside feels smoother and looks more reflective (silvery) compared to the coarser, darker top side.
Description
This is a primary flight feather from a Turkey Vulture, a large soaring bird with a wingspan of up to 6 feet. The bird is known for its bald red head (in adults) and its unique rocking flight style as it catches thermals. The feathers appear almost black from a distance but show a two-toned grey-and-black pattern from below in flight.
Key Features
The dark brownish-black coloration, large size, significant asymmetry of the vane, and the distinctive silvery-grey luster on the underside of the barbs.
Habitat
Highly adaptable, found in open areas, forests, grasslands, deserts, and suburban regions where carrion or thermal updrafts are available.
Geographic Range
Extensive range from southern Canada to the southernmost tip of South America. Northern populations are migratory, moving to the southern US and Central/South America during winter.
Condition Notes
Fair to Good. There is noticeable 'notching' or fraying at the tip and along the trailing edge, likely due to natural wear and tear or 'rubbing' against vegetation. No obvious fault bars or parasite damage are visible.
Interesting Facts
Turkey Vultures have an incredibly keen sense of smell, able to detect the gasses produced by decaying carcasses from miles away. They also practice urohidrosis, where they defecate on their own legs to cool down via evaporation.
Ecological Role
Essential scavenger. By consuming carrion, they help prevent the spread of diseases like anthrax and rabies in the environment. They occupy a high trophic level as specialized decomposers.
Similar Species
