Hyenas have 14 calls including whoops, grunts, groans, lowing, giggles, snarls, yelling and whines. The ‘whoop’ is the most conspicuous as it travels a great distance and is often heard at night as hyena advertise their presence or rally their clan members to assist with territory defence or the hunting of food.
Like lions, hyenas recognize one another’s calls and respond accordingly. Spotted hyenas are notorious for their giggled vocalization. This is emanated while feeding together on a kill as a sign of deference or included amidst a cacophony of different vocalizations during frantic encounters with lions.
