A study conducted in Kruger National Park, one of the most famous safari centers in the Republic of South Africa, and published in the journal Current Biology revealed that mammals living in the region are more scared of human voices than predators. In the study, speakers placed around the water sources in Kruger were used to record the sounds of humans and some other predators such as lions to the animals coming to drink water. One of the researchers, Prof. Dr. Liana Zanette from the Faculty of Biology at Canada Western University, shared some of the videos from the research on her YouTube channel. The videos show large mammals such as elephants, rhinos and giraffes panicking in the face of human voices and moving away from the environment. One elephant is also seen becoming aggressive at the sound of a predator and looking for the source of the sound to attack.
