Background information and definitions
Farmers could use loud-speakers to play primate alarm calls to deter primates from farms. A study that tested the influence of a combination of human and mechanical sounds, predator sounds, and vocalizations of other primates living in the same area, on primate activity budgets, found that play-backs of these sounds caused Cape baboons Papio ursinus to run more and feed less, but that there was no effect on the behaviour of vervet monkeys Chlorocebus pygerythrus (Richardson, 2014).
Using loud-speakers to broadcast sounds of potential threats to crop-raiding primates is discussed under ‘Use loud-speakers to broadcast sounds of potential threats (e.g. barking dogs, bird-fright explosions, gunshots)’.
