Turkey Vulture (also known as Turkey Buzzard, John Crow, or Carrion Crow)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Cathartiformes, Family: Cathartidae, Genus: Cathartes, Species: C. aura · Cathartidae (New World Vultures) · Primary flight feather (remiges), likely P4-P6 based on the significant emargination along the leading edge.
Species
Cathartes aura
Feather Type
Primary flight feather (remiges), likely P4-P6 based on the significant emargination along the leading edge.
Family
Cathartidae (New World Vultures)
Shape
Highly asymmetrical with an elongated, tapered outline. The outer vane is very narrow and strongly emarginated (notched), a classic aerodynamic feature for soaring birds.
Size
Estimated between 14-16 inches (35-40 cm) in length. This is consistent with a primary feather of an adult Turkey Vulture, whose primaries generally range from 30 to 45 cm.
Rarity
Very Common; one of the most widespread and frequently observed large birds in the Americas.
Color & Pattern
Bicolor pattern: the dorsal side (shown) features a dark brownish-black leading edge and distal tip, with a high-contrast silvery-grey to light tan inner vane and base. The rachis is pale cream or white.
Barb Structure
Densely interlocked pennaceous barbs on the majority of the vane for structural integrity during flight; the base near the calamus shows some plumulaceous (fluffy) downy structure for insulation.
Texture & Surface
The surface is matte and slightly stiff. The leading edge barbs are very rigid to maintain the airfoil shape, while the trailing vane is more flexible. It feels somewhat dry and non-oily.
Description
A large soaring bird with a wingspan of up to 6 feet. Turkey Vultures are recognizable by their dark plumage, featherless red heads (in adults), and their distinctive 'teetering' flight style in a V-shaped dihedral. This feather reflects the bird's two-toned underwing appearance.
Key Features
Diagnostic silvery-grey inner vane contrasting with dark outer vane; pale cream-colored rachis; distinct emargination on the leading edge for controlling wing-tip vortices.
Habitat
Extremely versatile: found in open country, subtropical forests, shrublands, deserts, and foothills. Often seen roosting in large trees or on rocky cliffs.
Geographic Range
Broadly distributed from southern Canada to the southernmost tip of South America. Northern populations are migratory, wintering in the southern US, Central, and South America.
Condition Notes
Fair to Good. There is visible 'zip' separation and fraying along the lower trailing edge, suggesting this may be a naturally molted feather that has experienced some mechanical wear or wind damage.
Interesting Facts
Turkey Vultures have an extraordinary sense of smell, capable of detecting the gases produced by decaying carcasses from miles away. Unlike most birds, they lack a syrinx and can only produce huffs or hisses.
Ecological Role
Scavenger; they provide a vital service by consuming carrion, which helps prevent the spread of diseases like anthrax and rabies in the environment.
