Do elephants mourn their dead ? It's a fascinating topic that we humans cannot even begin to understand because we can only view the behaviour through our own prism of emotions and understanding. Clearly elephants have a concept of death when we see them go quiet and nuzzle the bones of one of their own. Recenly I saw a doco that showed giraffe doing very much the same thing, arriving silently at the bones of one that lions had killed, sniffing and touching the pieces left with their noses and mouths then standing quietly looking down at what was left, just a huge leg bone with the hoof still attached. It was clearly some recognition but of what ? death or the familiar scent left of a giraffe they knew ? There is so much about the emotional lives of animals we simply cannot know.
