This troop of Langur Monkeys show empathetic behaviour as they mourn what they think is a dead baby Langur, which is actually a robotic spy monkey, designed to film the primates. This footage was filming whilst making the BBC series Spy In The Wild. The next episode will be on in the UK, on BBC One tonight at 8pm. The series will start in the US on February 1, 8-9 pm ET on PBS stations.
