"So, they eventually decided to choose the safe option, which was interesting." "You don't want to get involved with anything that has claws and teeth," says Thuppil. Leopard growls elicited a very different reaction-stomping, circling, and trumpet calls-although the elephants did eventually retreat. When the elephants heard the tiger growls, they crept silently away. Using video cameras camouflaged with elephant dung, they documented Asian elephants' reactions to pre-recorded tiger and leopard growls along village farm roads in southern India at night-prime raiding time. Thuppil and his colleagues wanted to test the strategy. So, what's new? A study published in Biology Letters today suggests that wild Asian elephants (Elephas maximus) can tell the growls of various big cats apart and know which pose more danger to them.Ĭo-author Vivek Thuppil, an animal behaviorist at the University of California, Davis, heard about a farmer in southern India who played a recording of a tiger growl to scare elephants off his property. Until now, researchers have focused on African elephants, but the first study with Asian elephants shows them to be equally adept at sensing threats. They also respond to the buzz of disturbed African honeybees, and can smell the difference between human friends and foes.Ĭonservationists hope to use elephants' keen senses to reduce conflicts that arise when elephants munch on humans' crops. "We know that African elephants have very sophisticated discrimination abilities," says Lucy Bates, a research fellow at the University of St. Not many predators can take down an elephant, so it's useful for the massive mammals to know when it's worth their effort to run away.

(See: " Older Elephants Know the Best Anti-Lion Moves.") Why does she care? Because male lions are more likely to attack. When an old African elephant matriarch hears a lion roar out on the savanna, she listens to discern whether it's a male or female.
