Cow goes moo. Frog goes croak. Giraffe goes…. hmm?
Zookeepers have always assumed giraffes were fairly silent creatures, with the occasional snort thrown in. The assumption was that their long necks restricted their ability to make sounds, and also that being noisy would attract predators.
But researchers from the University of Vienna challenged this assumption. After recording and studying 938 hours of giraffe sounds over an eight year period, the scientists have discovered that in fact giraffes do make sounds. They make low-pitched humming sounds at night.
