The turkey vulture, also known in some North American regions as the turkey buzzard, and in some areas of the Caribbean as the John crow or carrion crow, is the most widespread of the New World vultures. The turkey vulture is a scavenger and feeds almost exclusively on carrion. It finds its food using its keen eyes and sense of smell, flying low enough to detect the gasses produced by the beginnings of the process of decay in dead animals. This vulture is often seen standing in a spread-winged stance. The stance is believed to serve multiple functions: drying the wings, warming the body, and baking off bacteria. It is practiced more often following damp or rainy nights.
