Black Vulture (American Black Vulture)

This is a sturdy flight feather from a Black Vulture, a large raptorial scavenger with a wingspan of nearly 5 feet. Unlike the silver-trailed wings of the Turkey Vulture, the Black Vulture in flight shows distinct white 'stars' at the wingtips. The bird itself is coal-black with a naked, grey-skinned head and a short, squared tail. They are social birds, often seen soaring in 'kettles' or roosting together on towers.

Uniformly dark charcoal-grey to black on the dorsal surface. The underside (ventral) often appears slightly paler or more silvery-grey due to the structural reflection. The rachis is dark at the tip, transitioning to a pale, translucent cream/white at the base (calamus).

Densely interlocked pennaceous barbs on the majority of the vane for aerobic efficiency; the base transitions into a small plumulaceous (downy) section near the calamus. The barbs are stiff and resilient.

The surface is matte and slightly coarse to the touch. It lacks the oily sheen of waterfowl but is extremely rigid to withstand the pressures of thermal soaring and heavy wingbeats.

The combination of the deep black vane color, the extreme asymmetry of the flight feather, and the strikingly pale/white quill (calamus) at the base are the primary diagnostic markers.

Found in a variety of open and semi-open areas, including subtropical forests, swamps, pastures, and increasingly in suburban/urban environments like Port Charlotte where they scavenge.

Resident year-round from the southeastern United States (including all of Florida) down through Central America to central South America. They do not typically migrate long distances.

As an obligate scavenger, this species plays a vital 'sanitation' role in the ecosystem by consuming carrion and preventing the spread of diseases. They are currently a species of 'Least Concern'.

Turkey Vulture primaries are longer, slimmer, and usually more brownish-grey with a darker calamus. Crow primaries are much smaller and lack the extreme emargination at the tip.

Black Vultures lack a syrinx (vocal organ), so they can only make grunts or hisses. Unlike Turkey Vultures, they have a poor sense of smell and often follow Turkey Vultures to find carcasses.

Good condition. The feather shows minor wear and 'nicking' along the trailing edge, likely from use during flight or contact with vegetation. No significant fault bars are visible.
