Elephants Give a Helping Trunk
Elephants
 are known to be highly social and intelligent. Now there is evidence 
that they engage in something that looks very much like a group hug when
 a fellow elephant is in distress.
Joshua
 Plotnik, who leads a conservation and education group called Think 
Elephants, and teaches conservation at Mahidol University in Thailand, 
studied elephants at a park in Chiang Rai Province in Thailand, to look 
for consolation behavior.
As
 defined by Frans de Waal, Dr. Plotnik’s Ph.D. adviser at Emory 
University, consolation behavior involves bystanders responding in a 
reassuring way to an animal that is in emotional distress because of a 
conflict with another member of the group.
“We’re
 pretty confident it’s relatively rare” in animals, Dr. Plotnik said in 
an interview. He said there was good evidence for the behavior in apes, 
wolves and some birds. And he said there had been anecdotal reports of 
such behavior in dolphins and elephants.
Elephants
 clearly have strong emotional connections to other elephants and are 
highly intelligent, so it made sense to think that they might console 
one another. To find out, Dr. Plotnik observed 26 elephants in six 
groups at a managed park.
When
 one elephant was disturbed, Dr. Plotnik said, other elephants — 
bystanders — gathered around. They made chirping sounds and touched the 
distressed elephant, trunk to mouth or trunk to genitals, which are 
reassuring gestures, for elephants.
Dr.
 Plotnik said that since he couldn’t always observe the original source 
of the distress, he couldn’t say that the behavior met the narrow 
definition of consolation, as it was not clear whether it followed 
conflict. The elephants might have been scared by a person, dog, or, in 
some cases, a noise that humans couldn’t hear.
But, he said, in every other way the elephant behavior showed that they were acting to reassure elephants that were upset.
He and Dr. de Waal reported the findings in an article last week in PeerJ, an online scientific journal.
