Green Monkeys-snakes interactions records
- 1976, Senegal. Young green monkeys played (pulling the tail) with colubrid grass-snakes (not Naja) under their mother’s field of view, without showing the least fear reaction, neither by the young, nor by the mother or other adults.

Precisely, in this book, we let our “monkey hero” (a green monkey Chlorocebus sabaeus) “say”, summarizing our observations:
(Google translation from French) “Hazard gradation
I learned to discriminate between several categories of predators, whether they are terrestrial or aerial, dangerous for all or only for the youngest, hunters who need to be outdistanced, hunters on the lookout that to reveal with cries for them to go away, their strategy rendered obsolete. I also know how to recognize the different dogs individually in the neighbourhood and adjust my safety distance to their individual peculiarities: I warn the mothers with children of the arrival of the snarling mastiff, but I am content to push me a few meters in front of the lame old one. When a child plays with a snake, I let it go. The little ones always try to play; it is a way of learning, the other being to imitate those who know. If it had been a poisonous snake, I would have raised the appropriate alarm that would have dissuaded the youngster from pulling the tail of the animal at the same time as I would have instructed the other members of the presence of a dangerous terrestrial animal that should be harassed in a group to make it clear.”
- 1976, Senegal. Contagious alarm chutters and threat alarm like barks as green monkeys Chlorocebus sabaeus detected Naja senegalensis snakes (on the Senegal river bank, much further north than the IUCN map). These vocalizations where specific of ground slow predators hunting on the lookout. In one case, as usual, Gerard was followed by a specific adult female we named “Bou” (Anh was also usually followed by a specific adult male). Seeing a Naja straightened in defensive display, Gerard stopped, freezing. Noticing Gerard’s behaviour, “Bou” stood on his hind legs, noticed the snake, and emitted a call souding like a chutter and like a high-pitched threat alarm call. Some of the other monkeys of the troop checked in our direction, but continued on their way. None came to check what happens.
