- Shape
- Highly asymmetrical vane; narrowed leading edge (outer vane) with noticeable emargination (notching) for aerodynamic slotting; broad trailing edge (inner vane); rounded to slightly tapered tip
- Size
- Estimated 25 to 30 cm (10-12 inches) in length; the width is approximately 4-5 cm. This is consistent with the primary feathers of an adult Black Vulture

Description
A soot-black bird with a naked, wrinkled grey head. In flight, it is distinguished from the Turkey Vulture by its shorter tail, broader wings, and distinctive white patches at the wingtips. It has a heavy, flapping flight style and often soars in large groups called kettles.
Colour & Pattern
Uniformly charcoal black to deep sooty grey with a subtle matte finish; dorsal surface shows a faint oily sheen; ventral (underside) surface is slightly paler grey; rachis is dark but transitions to a lighter, creamy tan at the calamus (quill)
Barb Structure
Tightly interlocked pennaceous barbs throughout the majority of the vane for flight rigidity; some plumulaceous (downy) barbs at the very base of the calamus for insulation
Rachis & Barb Pattern
Thick, sturdy rachis that is dark on the upper side and pale underneath; significant curvature toward the body; barb density is high and uniform to maintain a solid air-resistant surface
Texture & Surface
Stiff and rugged; the surface is somewhat coarse to the touch compared to waterbirds; lacks the 'velvet' silent-flight adaptation of owls; noticeably matte under direct light
Feather Placement
Outer wing (Primary). The extreme asymmetry and stiff rachis are diagnostic of a primary feather responsible for generating lift and thrust
Key Features
Deep charcoal color without banding; extreme asymmetry of the vane; pale/creamy calamus; distinctive notch on the leading edge for air slotting
Habitat
Highly adaptable: found in open landscapes, forests, wetlands, agricultural areas, and increasingly in urban or suburban environments where human refuse is available
Geographic Range
Resident year-round from the southeastern United States through Central America and across nearly all of South America, including all regions of Brazil
Ecological Role
Scavenger/Decomposer; plays a vital role in cleaning the environment by removing carrion and preventing the spread of diseases such as anthrax and rabies
Similar Species
Turkey Vulture (Cathartes aura) feathers are more brownish-black and have a silvery-grey underside throughout the wing. Crested Caracara feathers are banded/mottled. Neotropic Cormorant feathers are glossier and narrower.
Interesting Facts
Unlike Turkey Vultures, Black Vultures have a poor sense of smell and often follow their cousins to carcasses. They are highly social and are known to feed in large, organized groups with a strict social hierarchy.
Cultural Significance
In Mayan mythology, vultures were seen as symbols of transformation and cleansing. Historically used in some indigenous South American rituals, though less common than Macaw feathers due to their somber color.
Field Identification Tips
Look near carcasses, large roosting trees (often near water or tall structures), or urban dumpsters in Brazil. Primary feathers are usually dropped during the summer molt.
Condition Notes
Good condition; minor fraying at the tip and trailing edge suggests natural wear from flight; the calamus is fully formed and clear, indicating a naturally molted feather
