Daily Activity Budget of Dusky Leaf Monkey, (Trachypithecus obscurus) At Taman PD Utama, Port Dickson, Negeri Sembilan, Peninsular Malaysia

A study to obtain the daily activity budget of the dusky leaf monkey (Trachypithecus obscurus) in Taman PD Utama, Port Dickson, Negeri Sembilan, Peninsular Malaysia. This study aims to understand this species’ activity budget in the urban environment, focusing on time-use allocation on behaviours such as moving, feeding, playing, vocalization, resting, grooming, and mothering. Observational data on these monkeys’ activities were collected to establish their daily routine. The study involved a group of dusky leaf monkeys, comprising 12 to 18 members. During the 20 days of observation, it was found that resting accounted for 28.3% followed by moving (27.08%), feeding (20.85%), playing (8.02%), mothering (7.36%), grooming (6.04%), and vocalization (2.36%). The collection of this data is to show how they adapt to urban areas and how they behave depending on other resources and conditions. These findings shed light on their adaptation to urban environments and behaviour in response to resource availability and environmental circumstances. This study helps to understand the behavioural ecology of the dusky leaf monkey, giving crucial information for future management and conservation efforts and emphasising the significance of protecting urban green areas for wildlife.
