There are many false tales and theories about animal behavior. Most people, for example, think that when vultures are seen circling an area, they have located a meal. More often than not, they're actually riding thermals (rising air currents) to gain altitude and have a better vantage point for sniffing out carrion. When vultures locate a scent source, they don't waste time circling. They go straight to the food. This is but one example of humans misunderstanding nature.
