Animal Grief: Mourning and Loss in the Animal Kingdom

Evidence from across the animal kingdom shows that many species experience grief and mourning after the loss of companions.

Key Facts

Elephants have been documented returning to the bones of dead companions repeatedly over years
Orca mothers have been observed carrying dead calves for up to 17 days
Chimpanzees have been documented cleaning and guarding the bodies of dead companions
Crows hold group gatherings around dead flock members in apparent mourning behavior
Domestic dogs show behavioral changes consistent with grief after the loss of companions

Welfare Considerations

Animal grief demonstrates that many species form deep social bonds whose disruption causes lasting psychological harm. This has profound implications for how we treat animals who experience loss from human activities: culling programs that break social groups, factory farming practices separating bonded animals, and wildlife management that does not consider social structure all cause grief-related suffering that is systematically ignored.
