Elephants are highly social animals and have a well-developed method of communicating with each other. For nearly 30 years, scientists at a national park in Kenya have been studying elephants and their behavior. The researchers have found that these intelligent beasts use more than 70 kinds of vocal sounds and 160 different visual and tactile signals, expressions, and gestures in their day-to-day interactions. This Web site describes the project and provides fascinating material on how and why elephants communicate.
