Distinctive Features

The pig-tailed macaque has a robust body, measuring around 45–60 centimetres in females and more than 70 centimetres in males. Adults weigh approximately 5–15 kilograms. Its most distinctive feature is its short, curved tail resembling that of a pig, giving rise to its common English name, pig-tailed macaque.

Its coat ranges from olive brown to dark grey, with lighter-coloured underparts. Its strong limbs support a largely terrestrial lifestyle, with the species spending more time on the ground than several other Macaca species.

Active, Intelligent and Social

The pig-tailed macaque is diurnal, meaning it is active during the day. It lives in groups consisting of males and females, typically numbering around 15–40 individuals.

Within the group, macaques display a range of social behaviours, including grooming, vocal communication, play and dominance interactions. Their ability to recognise individuals, understand visual cues and adjust their foraging behaviour demonstrates a high level of social intelligence.

A Varied Diet, Strong Adaptability

The pig-tailed macaque is an omnivore, with fruit forming one of its main food sources. It also feeds on seeds, young leaves, flowers, fungi, insects, small crustaceans, bird eggs and small vertebrates.

Its ability to utilise a wide range of food sources helps it adapt when food availability changes. In modified habitats, pig-tailed macaques may also feed on cultivated plants such as oil palm, bananas and root crops. This can increase interactions between the species and human communities.

Vulnerable and in Need of Protection

The International Union for Conservation of Nature (IUCN) classifies the pig-tailed macaque as Vulnerable. This status indicates that the species faces a risk of extinction in the wild if threats to its habitat and population are not properly managed.

Protecting the pig-tailed macaque also means protecting the habitat and ecological processes that sustain the forest.

Dispersing Seeds, Sustaining Forests

As a fruit-eating species, the pig-tailed macaque plays a role in seed dispersal. Seeds carried through feeding and movement can be deposited in different areas, supporting the natural regeneration of vegetation. This role highlights how every species contributes to a functioning ecosystem. The pig-tailed macaque is not simply a forest inhabitant; it is part of the natural process that helps forests continue to grow and regenerate.

This method utilises recordings of wildlife and environmental sounds as indicators to better understand species presence, activity, and ecosystem dynamics. Through the installation of automated sound recording devices (passive acoustic recorders) at several strategic locations, such as preservation zones, various wildlife sounds can be continuously recorded without disturbing their natural habitats.

The sounds of birds, amphibians, insects, and vocal mammals form part of the data analysed to identify species composition, daily activity patterns, and changes in ecosystem conditions over time. This approach enables monitoring to be conducted in a more efficient, objective, and long-term manner, including in areas that are difficult to access through conventional field surveys.

In addition to complementing visual field observations, Bioacoustic Monitoring also assists in identifying species that are typically difficult to detect, including nocturnal wildlife. The data collected subsequently becomes an important component in evaluating the effectiveness of conservation area management and rehabilitation efforts surrounding the Company’s operational areas.

The implementation of this method also supports an adaptive management approach, whereby monitoring results are used as the basis for developing more targeted environmental protection and management measures. Through the early identification of key wildlife species and indications of environmental disturbance, the Company can respond more effectively by adjusting its conservation strategies.

Through the implementation of Bioacoustic Monitoring, Agincourt Resources continues to strengthen the integration of modern scientific technology into responsible mining practices. This approach forms part of the Company’s ongoing efforts to preserve biodiversity, enhance environmental management transparency, and support its Environmental, Social, and Governance (ESG) commitments.
