In this excerpt from the first episode of the animated documentary "Spy in the Wild" aired on the British channel BBC, a group of monkeys "Semnopithecus", also called langurs, tries to interact with a baby monkey spy automaton. Unfortunately, by wanting to mother the robotic doll, one of the monkeys makes it fall from a branch. The group of langors then thinks that the baby is dead. There follows a collective mourning movement following this tragic event. The spy robot is moved on rocks and the monkeys gather around it reacting in the same way as when one of their cubs has just died.
