Primary flight feather (Remex), likely P7-P9

Black Vulture

Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Cathartiformes, Family: Cathartidae, Genus: Coragyps, Species: Coragyps atratus

Family: Cathartidae (New World Vultures)

Shape
Highly asymmetrical, elongated, and slightly curved with a rounded-to-blunt tip. The leading edge (outer vane) is significantly narrower than the trailing edge (inner vane).
Size
Approximately 32-38 cm (12.5-15 inches) in length. This is consistent with the outer primaries of an adult specimen, which provide the lift required for soaring.
Rarity
Very Common. They are abundant and frequently seen soaring in thermals or gathered at roadkill sites.

Description

The Black Vulture is a large, bulky raptor with a short tail and broad wings. In flight, it is distinguished from the Turkey Vulture by its black head and the white 'stars' or patches localized only at the wingtips. They have a flapping-and-gliding flight style, lacking the steady rocking 'dihedral' of their cousins.

Colour & Pattern

Uniformly dark charcoal grey to black on the dorsal surface. The ventral side (underside) often shows a slightly more silvery or lighter grey sheen, which is diagnostic of Black Vulture primaries compared to Turkey Vultures.

Barb Structure

Tightly interlocked pennaceous barbs for aerodynamic integrity. The base transitions into soft, plumulaceous (downy) barbs for insulation. The barbs are stiff and resistant to wind pressure.

Texture & Surface

Coarse, stiff, and matte. The surface is not particularly glossy, as these birds spend significant time in the sun which can lead to a weathered look. The vane is rigid to withstand high-altitude wind.

Key Features

Large size, deep black coloration, extreme vane asymmetry, and the characteristic pale/whitish quill base that transitions into a dark rachis.

Habitat

Found in a variety of environments including open forests, agricultural lands, urban areas, and landfills. Often seen roosting in tall trees or on man-made structures in Conroe, TX.

Geographic Range

Common resident throughout the Southeastern United States (including Texas), Central America, and most of South America. They are non-migratory in the southern portion of their range.

Ecological Role

Nature's clean-up crew. As scavengers, they play a vital role in preventing the spread of diseases by consuming carrion. They are top-tier scavengers in the food web.

Similar Species

Turkey Vulture (Cathartes aura) feathers are more brownish and have a lighter/silvery sheen across the entire inner vane. American Crow feathers are much smaller and glossier.

Interesting Facts

Unlike Turkey Vultures, Black Vultures have a poor sense of smell and often follow Turkey Vultures to find food. They are also very social birds with strong family bonds, often sharing food with kin.

Condition Notes

Good condition. The barbs are mostly intact, though some minor fraying is visible at the trailing edge, likely due to natural wear and tear or 'molt-drop' contact.
