Turkey Vulture (also known as Turkey Buzzard, John Crow, or Carrion Crow)

A large soaring bird with a wingspan of up to 6 feet. Turkey Vultures are recognizable by their dark plumage, featherless red heads (in adults), and their distinctive 'teetering' flight style in a V-shaped dihedral. This feather reflects the bird's two-toned underwing appearance.

Bicolor pattern: the dorsal side (shown) features a dark brownish-black leading edge and distal tip, with a high-contrast silvery-grey to light tan inner vane and base. The rachis is pale cream or white.

Densely interlocked pennaceous barbs on the majority of the vane for structural integrity during flight; the base near the calamus shows some plumulaceous (fluffy) downy structure for insulation.

The surface is matte and slightly stiff. The leading edge barbs are very rigid to maintain the airfoil shape, while the trailing vane is more flexible. It feels somewhat dry and non-oily.

Diagnostic silvery-grey inner vane contrasting with dark outer vane; pale cream-colored rachis; distinct emargination on the leading edge for controlling wing-tip vortices.

Extremely versatile: found in open country, subtropical forests, shrublands, deserts, and foothills. Often seen roosting in large trees or on rocky cliffs.

Broadly distributed from southern Canada to the southernmost tip of South America. Northern populations are migratory, wintering in the southern US, Central, and South America.

Scavenger; they provide a vital service by consuming carrion, which helps prevent the spread of diseases like anthrax and rabies in the environment.

Black Vulture (shorter, wider feathers with more extensive white at tips); California Condor (much larger, darker rachis); Golden Eagle (lack the uniform silvery-grey inner vane and have darker shafts).

Turkey Vultures have an extraordinary sense of smell, capable of detecting the gases produced by decaying carcasses from miles away. Unlike most birds, they lack a syrinx and can only produce huffs or hisses.

Fair to Good. There is visible 'zip' separation and fraying along the lower trailing edge, suggesting this may be a naturally molted feather that has experienced some mechanical wear or wind damage.
