The team found that there were different calls, or “words”, for a range of predators, including leopards, tigers, pythons and eagles. The whispers even distinguished between different types of birds that were physically similar, such as eagle owls and serpent eagles. The bird calls were the quietest, below 1 kHz, and which raptors would struggle to hear. Tiger and leopard hoos were similar, suggesting that callers perceived these two predators as belonging to the same “big cat” class.
