How to Identify Grief in Animals

[Still Waters]

Many species mourn the passing of loved ones, but not every animal response to death qualifies as grief.

"Based on the photograph alone, though, we lack the information to invoke credibly a group-wide grief response; riveted and silent attention is not the same as mourning, and may occur also with intense curiosity"

So what would be their criteria for discerning grief in chimps? Whatever they might be, I would bet money that you could find many humans who do not exhibit these behaviours, does that mean they do not grieve?

I was trying to find an excerpt on animal grief in Darwin's seminal 1873 book The Expression of the Emotions in Man and Animals but I found this interesting observation first.

"There is a very elaborate discussion on blushing. This is a peculiarly human attribute, being observed in almost every race of man, but not in the lower animals."

Which reminded of this quote;

"Man is the only animal that blushes. Or needs to." - Mark Twain,
