The most groundbreaking discovery in giraffe communication occurred when researchers utilized sensitive recording equipment to monitor giraffes at night. They discovered that giraffes "hum." These nocturnal vocalizations are low-frequency sounds—often infrasonic, meaning they fall below the threshold of human hearing. These hums are rich in structure and vary in duration, suggesting that they serve as a primary means of maintaining contact within the herd when visibility is low. Because giraffes have such long necks, the physical effort required to push air from the lungs past the vocal cords is significant, which may explain why they favor these deep, resonant frequencies over frequent high-pitched calls.
Beyond the mysterious humming, giraffes also communicate through more audible means, particularly in moments of high emotion or stress. Calves are known to emit "bleats" or "mews" to call for their mothers, similar to the sounds made by calves of other ungulate species. Adult giraffes have been documented producing snorts, grunts, and even hisses. A snort often serves as an alarm signal to warn the rest of the herd of a nearby predator, such as a lion. These sounds are functional and direct, proving that while the giraffe is not "chatty" in the way a bird or a primate might be, it is far from mute. Zurafe Sesi YГјkle
Snorts (alarm), moans (stress), and bellows (aggressive intent). Because giraffes have such long necks, the physical
