The rock hyrax is a surprisingly sophisticated communicator, a study published in a Royal Society journal suggests.
The small mammal is extremely vocal: males sing complex songs that can last for several minutes.
But now scientists have discovered that the order of the notes is significant, suggesting that the songs have syntax.
The team also found that hyraxes from different regions had a different dialect when they warbled.
