National Geographic:

Queen Victoria, one of the last surviving old matriarchs in the Samburu National Reserve in northern Kenya, died of natural causes in 2013, with her family members close by.

Victoria headed an elephant group known on the Samburu Reserve as the Royal family, a group of about 20 elephants all named after kings, queens, and other royalty around the world.

(this) 15-minute video of the elephants’ investigation, made available exclusively to National Geographic for the first time, is an important new addition to the growing body of research about the complexity of elephant thought and perception and their responses to death. The video not only captures an important ritual of elephant behavior, but reveals new insights about the strength of social bonds.

Sad but remarkable video. I don’t know if the elephants are grieving in the human sense but they are certainly acknowledging the passing of their matriarch.
