Abstract


Northern pigtail macaque (Macaca leonina) is thought to naturally distribute in South Vietnam, where it adapts to high daily temperature. In Hanoi Zoo, Northern Vietnam, time budget and diet of a 10-individual group of Northern pigtail macaque (Macaca leonina) and the impact on some ecological factors (temperature, humidity, human impact) were studied to determine how the species can adapt to cool and cold weather in Northern Vietnam, as well as the influence of the above factors on its behaviour. Methods used are focal time sampling and ad libitum. Results showed that the species activities have not been influenced remarkably by temperature and humidity, but they have been strongly impacted by humans and there were linear regressions between the human impact and several activities of the monkey.
