Turkey Vulture
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Cathartiformes, Family: Cathartidae, Genus: Cathartes, Species: aura
Family: Cathartidae (New World Vultures)
- Shape
- Strongly asymmetrical with a broad, rounded tip. Leading vane is significantly narrower than the trailing vane, typical of flight feathers designed for lift.
- Size
- Estimated 25 to 32 cm in length. This matches the known range for the secondary feathers of an adult Turkey Vulture which possess a robust calamus.
- Rarity
- Very Common; one of the most widespread and frequently observed raptors in the Western Hemisphere.

Description
Large, dark raptor with a 6-foot wingspan. Adults have a featherless red head, while juveniles have grey-black heads. They are famous for their 'teetering' flight (dihedral wing shape) and incredible sense of smell used to find carrion.
Colour & Pattern
Uniformly dark brown or 'blackish' on the dorsal surface. The ventral side (visible in flight from below) typically appears lighter or silvery-grey, which is a key diagnostic feature for this species. The rachis is noticeably pale/white near the base.
Barb Structure
Densely packed pennaceous barbs throughout the majority of the vane for aerodynamic integrity, with a small cluster of plumulaceous (downy) barbs at the base for insulation.
Texture & Surface
Relatively stiff and coarse compared to songbirds. The surface has a matte finish, typical of vultures, which lacks the oily waterproofing of waterfowl.
Key Features
Large size, uniform dark chocolate/black coloration, and a distinctively pale/white calamus and lower rachis.
Habitat
Extremely versatile; found in open country, subtropical forests, shrublands, deserts, and pastures where carrion is accessible. Frequently seen soaring over roadsides.
Geographic Range
Broad distribution covering most of the Americas, from southern Canada to the southernmost tip of South America. Many northern populations are migratory.
Ecological Role
Primary scavenger; they play a critical role in 'cleaning' the environment by consuming decaying carcasses, which helps prevent the spread of diseases like anthrax and tuberculosis.
Similar Species
Black Vulture (feathers are shorter and more truly black), Golden Eagle (shows distinct banding or white patches in juveniles), and Common Raven (feathers are glossier and have different base structure).
Interesting Facts
Unlike most birds, Turkey Vultures have a highly developed sense of smell, allowing them to locate carcasses hidden under dense forest canopies. They also practice urohidrosis, defecating on their legs to cool down through evaporation.
Condition Notes
Good; the vane is largely intact with minor 'zipping' issues at the tip. No obvious signs of parasitic damage or heavy wear from a late-season molt.
