Hyenas' 'laughter' signals food and coordinates hunts

Spotted hyenas' distinctive 'laughter' isn't just for show; these high-pitched giggles primarily signal food finds and coordinate group activities. Most common among subordinates and cubs, this vocalization helps maintain social order during feeding frenzies and alerts the clan to resources. It's a key part of their complex communication, alongside long-distance 'whoops' that rally clan members up to three miles away.
