Elephants exhibit compassion, kindness, intelligence having the largest brains especially the memory portion of any species. Subsonic communication allows them to warn other elephants 90 miles away of culling.
Lawrence Anthony wrote The Elephant Whisperer: My Life with the Herd in the African Wild (with Graham Spence) about his experience rescuing a small elephant herd whose matriarch had been murdered. People began to call him the Elephant Whisperer.
When Anthony passed away on March 7, 2012, elephants assembled from all over Zululand walking slowly for 2 days to surround his house at Thula Thula Game Reserve to morn his passing, saying "good bye" to the man who had saved them at his funeral on March 10, 2012. It is perhaps even more remarkable that these elephants repeat this ritual each year, mourning the passing of the elephant whisperer!
The elephant procession is shown below in these 2 photos. Elephants not only weep for their family; but caress bones of unknown elephants.
