What is elephants trumpeting?

Elephants trumpet to communicate with each other over long distances. The sound is produced by blowing air through their trunk, which can make different sounds depending on the amount of air pressure and the position of their trunk. Trumpeting can also signal a variety of emotions such as excitement, aggression, or fear. Additionally, elephants may trumpet when they are startled or feel threatened, as a way to intimidate or warn potential predators or humans. Overall, elephants use their trumpeting as a means of communication and to express their emotions.
