Do Giraffes Hum to Communicate?

💡 The Answer

• Researchers have discovered that giraffes produce low-frequency humming sounds to stay in contact.
• These hums likely serve as 'contact calls' for individuals who have been separated from their herd.
• The humming is most frequently recorded at night, helping the animals find each other in the dark.
• Some evidence suggests that giraffes may even engage in a form of 'sleep talking' while resting.
