Elephants’ intense fear of bees may just save their lives.
One of the most common causes of death for Asian elephants in India isn’t poaching (due largely to their smaller tusk size), but train accidents.
From 1987 through July 2017, 266 elephants have been hit by engines in the second most populous country in the world. So far in 2018, 15 elephants were killed on the tracks. Experts think the numbers could be due to more trains, faster trains and/or a burgeoning elephant population, but measures such as warnings and reduced train speeds haven’t necessarily made a measurable impact on mitigating deaths.
Despite their thick skin, both Asian and African elephants are so terrified of bee stings that the vast majority will turn to run “within seconds of hearing the sound of buzzing,” scientists explain. No one is yet exactly sure why that is the case, but organizations in elephant-populated areas have been experimenting for years with using bees and bee sounds to repel pachyderms.
The Forest Department in India has been using drones that emit buzzing-bee sounds to scare elephants away from neighborhoods, farmland and areas known to be frequented by poachers, and farmers in Africa have installed beehives to keep the elephants from eating their crops. African elephants are reportedly even more afraid of bees than Asian elephants; experts surmise this could be because bees in Asia are less aggressive than those in Africa.
Late last year, rail officials in eastern India began installing devices alongside the train tracks that emit bee sounds downloaded from the internet, and it seems to be working: This year only six elephants have died from train accidents in the immediate area, compared with 10 at this time in 2017.
“We installed this in Rangiya division, and once it was successful we have installed it in other locations as well. This was started barely six months back,” Lokesh Narayan, additional general manager of Northeast Frontier Railway, told The Times of India.
