Grief in animals: It's arrogant to think we're the only animals who mourn
Among the different emotions that animals display clearly and unambiguously is grief. Many animals display profound grief at the loss or absence of a close friend or loved one. Nobel laureate ethologist Konrad Lorenz writes: "A greylag goose that has lost its partner shows all the symptoms that [developmental psychologist] John Bowlby has described in young human children in his famous book Infant Grief . . . the eyes sink deep into their sockets, and the individual has an overall drooping experience, literally letting the head hang . . ." Sea lion mothers, watching their babies being eaten by killer whales, wail pitifully, anguishing their loss. Dolphins have been seen struggling to save a dead infant and mourn afterward. Stories about grief stricken companion animals abound; see also).
