Animals at watering holes in South Africa were twice as likely to flee in response to recordings of humans talking compared with sounds of lions
People’s voices frighten wildlife in the savannah even more than the growls and snarls of lions, suggesting that we are the scarier predator.
They set up loudspeakers and cameras on trees 10 metres away from animal paths near 21 waterholes in Greater Kruger National Park, South Africa, which hosts one of the largest remaining lion populations in the world.Sign up to newsletterspeakers automatically played back one of four kinds of audio recordings, all at the same volume.
The researchers captured 15,000 videos of 19 species of carnivores and herbivores reacting to their recordings. They found that wildlife ran around in response to human voices more than to any other sounds, and were also 40 per cent quicker to flee – abandoning the water hole even during the dry season – when hearing humans compared with lion or hunting sounds. The animals were unlikely to have learned these fear reactions through their limited exposure to humans, says Clinchy.
