Japanese train barks and snorts to protect deer from harm
Researchers from the Railway Technical Research Institute in Japan have equipped a train with a speaker that plays the sounds of dogs barking and deer snorting to protect deer from harm. A three-second deer snort is played first to catch the attention of any nearby deer, followed by 20 seconds of dog barking to scare the animals away. So far, late-night tests of the anti-deer device have proven successful, resulting in a reduction in deer sightings by half. If further evidence supports the practice, it may be adopted more broadly, though the deer-dog combo noise would likely not be blasted in residential areas.
