The most common sound is a loud “shout” heard over a radius of several kilometers. This sound is used to summon clan members to defend territory, and indicate food supplies or danger. Other sounds include the “grunt,” the high-pitched cry-like sounds of young individuals that signal hunger, and cow-like sounds that put group members in a state of excitement.
There is also a sound resembling human laughter. Their rich repertoire of laughter is a sophisticated way of communicating. With a “giggle,” spotted hyenas communicate their species’ age, rank in the herd, and intentions. They emit a poignant giggle when they are preparing to attack.
