Turkey Vulture
Primary flight feather, likely P8 or P9

Turkey Vulture

Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Cathartiformes, Family: Cathartidae, Genus: Cathartes, Species: C. aura

Family: Cathartidae (New World Vultures)

Shape
Highly asymmetrical with a narrow, stiff outer vane and a broad inner vane; notable emargination (notching) on the inner vane near the tip to reduce drag/turbulence.
Size
Estimated 35-42 cm (14-16.5 inches) in length. This is consistent with a large primary feather from a medium-to-large raptorial bird.
Rarity
Common; one of the most widespread and frequently observed large birds in the Americas.

Description

The Turkey Vulture is a large soaring bird with a wingspan of up to 6 feet. It is easily identified in flight by its 'V-shaped' dihedral and rocking side-to-side motion. Adults have a bald red head, while juveniles have gray heads. The feathers are primarily blackish-brown.

Colour & Pattern

Uniform dark chocolate brown to brownish-black on the upper surface. The underside (ventral) often shows a silvery-gray sheen characteristic of the species. The rachis transitions from a translucent white at the base to a dark brown distal tip.

Barb Structure

Densely packed pennaceous barbs on the distal portion for aerodynamic integrity; larger, thicker barbicels for wind resistance; the base of the vane shows slight plumulaceous tendencies.

Texture & Surface

Relatively coarse and stiff compared to songbirds; the surface has a slight matte-to-semi-gloss finish. The feather feels slightly oily, which aids in water shedding.

Key Features

Large size, extreme asymmetry of the vanes, thick pale calamus, and the characteristic silvery cast on the underside of the barbs.

Habitat

Found in a wide 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

Range extends from southern Canada to the southernmost tip of South America. Northern populations are migratory, traveling in large kettles to Central and South America for winter.

Ecological Role

Vital scavenger and 'nature's cleanup crew.' By consuming carrion, they help prevent the spread of diseases like anthrax, botulism, and rabies in the environment.

Similar Species

Black Vulture (shorter, broader, more blunt tip), California Condor (significantly larger with different rachis color), and Golden Eagle (usually shows more mottling or lighter banding at the base).

Interesting Facts

Turkey Vultures have an extraordinary sense of smell, capable of detecting the gases produced by decaying carcasses from miles away. They also practice urohidrosis—distal excreting onto their legs—to cool down via evaporation.

Condition Notes

Fair to Good. There is significant 'zipper' damage (separation of barbs) near the tip and some fraying along the trailing edge, likely due to wear or contact with vegetation during roosting.
