The langurs brought us to the coastline for their foraging routine. While they were moving along the concrete divider, we spotted something unusual, where there was human junk food scattered on the divider platform - left over by the human, which we suspected those are for the long-tailed macaques.
We were worried that the langurs may get curious to taste the food on the platform. Surprisingly, the langurs ignored the junk food completely. It started off with the alpha male stared at the food for a while, then walked over the invasive food source. The others followed, where some of them avoided the food by leaping to the nearby vegetation while the rest just ignored and walked away. Therefore, the langurs don't need human food to survive, they have their natural food resources to depend on!
Many people feed wild animals due to sympathy and developed from the habit of feeding domestic animals. However, from the perspective of wildlife, the species are meant to be foraging and feeding in their natural habitat, with special diet requirement and unique foraging behaviour. Take dusky langurs as an example, these primates are folivorous, where they mainly feed on leaves and their digestive system is able to process plant material from a wide variety of plant species by fermentation. Feeding them the wrong food will cause digestion problem and may lead to serious consequences.
Human food is not a good option for primates as full of preservatives, colouring and most importantly, it is not the natural food source for the animals. If you love wildlife, appreciate them from a safe distance and do not interfere with their life! Say no to Feeding Primates as this seems to be "sympathy action" can lead to over-habituation & loss of foraging instinct among primates, disease transmission (among primates and human), expose the primates to poaching possibility, and aggression toward human (human-primate conflict).
