Turkey Vulture (also known as Turkey Buzzard, John Crow, or Carrion Crow in some regions)
Kingdom: Animalia; Phylum: Chordata; Class: Aves; Order: Cathartiformes; Family: Cathartidae; Genus: Cathartes; Species: Cathartes aura
Family: Cathartidae (New World Vultures)
- Shape
- Broad and somewhat rectangular with a rounded, blunt tip. The vane is slightly asymmetrical, typical of a secondary feather, being wider on the trailing edge than the leading edge.
- Size
- Estimated 10-12 inches (25-30 cm) in length. This is consistent with the secondary feathers of an adult Turkey Vulture, which typically fall in the 22-32 cm range.
- Rarity
- Very Common. It is one of the most frequently seen large raptors in North America.

Description
This large feather belonged to a Turkey Vulture, a bird with a 6-foot wingspan and a distinctive red, featherless head. Adult birds are almost entirely blackish-brown. In flight, they are easily identified by their 'V-shaped' dihedral wing position and their habit of rocking or teetering in the wind as they search for carrion using their keen sense of smell.
Colour & Pattern
Uniformly dark brownish-black to charcoal on the dorsal (upper) surface. The ventral (under) surface typically shows a silvery-grey or paler sheen, especially on the barbs, which is a diagnostic trait for the species in flight.
Barb Structure
Firmly interlocked pennaceous barbs on the majority of the vane, transitioning to soft, plumulaceous (downy) barbs at the base of the quill (calamus). The barbs are dense and designed for efficient soaring.
Texture & Surface
Matte finish with a slightly coarse, stiff texture. It lacks the oily gloss seen in waterfowl but has a natural waxy coating to resist moisture. The trailing edge is softer than the leading edge.
Key Features
Uniform dark charcoal color, large size, rounded tip, and the characteristic silvery sheen on the underside of the barbs (though less visible in this lighting).
Habitat
Extremely versatile: found in open areas, forests, grasslands, deserts, and suburban environments. Prefers areas with thermal updrafts for soaring and nearby roosting trees or cliffs.
Geographic Range
One of the most widespread birds in the Americas. Ranges from southern Canada down to the southernmost tip of South America. Northern populations are migratory, moving to the southern US and further south in winter.
Ecological Role
Scavenger/Decomposer. They play a critical role in the ecosystem by removing carrion, which helps prevent the spread of diseases like anthrax and rabies. They are an essential 'clean-up crew.'
Similar Species
Black Vulture (shorter, broader feathers, often with more white at the tips of primaries); Bald Eagle (immature eagle feathers are larger, darker, and have a different rachis structure); Golden Eagle (usually shows more subtle mottling or tawny coloration).
Interesting Facts
Turkey Vultures are among the few birds with a highly developed sense of smell, allowing them to find carrion hidden under forest canopies. They have a unique defense mechanism: they can projectile vomit putrid, semi-digested meat to deter predators.
Condition Notes
Fair to Good. There is some wear and 'zipping' issues at the tip (separated barbs), and the base shows some dirt. The fraying suggests it was a naturally molted feather that spent some time on the ground.
