Turkey Vulture
They feed almost exclusively on carrion (the decaying flesh of dead animals). Using keen vision and smell, it detects gasses produced by decaying animals.
They use thermal wind for flight and rarely flap their wings. (They are riding warm thermal air, not circling dying animals. They can smell dead animals, not dying animals).
Spread-wing stance allows them to dry their wings, warm their body, and bake off bacteria.
Often defecates on their own legs, using the process of evaporation to cool itself.
Self defense - regurgitates semi-digested, foul-smelling meat to deter predators.
