Through this act, the animal tells the other males not to seek a fight, in addition, in this way it also tries to persuade the females.

Since gorillas live in flocks that usually consist of one male and several females, and they can always switch groups, they struggle to get their attention.

As the research indicates, the sounds are likely related to the size of the air sacs near the larynx of gorillas and some other similar animals.
