What do I do when I want to contact a friend?
Well, of course, I just reach for my mobile phone and text or place a call. Or I can always email.
But what if I were an elephant? How would my friend know that I was calling him or her?
This is not a problem for a group of elephants who live in the Amboseli National Park in Kenya.
