The most visible mammal in the MacRitchie forest is the Long-tailed macaque (Macaca fascicularis) (above image by YC Wee). They can be easily seen, especially in the Jelutong Tower LINK. They can be aggressive as they are used to being fed by humans. However, do not make eye contact and keep foodstuff out of view.
The largest mammal in this forest is the Lesser Mousedeer (Tragulus kanchil) (above image by Lena Chow). However, it is seldom encountered as it only emerges from hiding at dawn and dusk to look for food. The male has a pair of long canine teeth but no antlers.
Plantain squirrel (Callosciurus notatus singapurensis) is widespread in the forest as well as in urban areas (above-left image by YC Wee). They can be seen scrambling along the ground and branches looking for food. It has a prominent reddish-brown belly bounded by a black and white stripe on each side, thus its other common name of Common Red-bellied Squirrel. The Slender Squirrel (Sundasciurus tenuis) is omnivorous and can be seen here as well as in the Botanic Gardens and Bukit Barok Nature Park (above-right image by Lena Chow).
The Toddy Cat, also known as Common Palm Civet (Paradoxurus hermaphroditus) is largely nocturnal and found among the trees (above image by Francis Yap). They have now invaded parks and gardens.
The Sunda Pangolin (Manis javanica) is a nocturnal creature (above-left image by KC Tsang). It is easily recognised by the many overlapping hard brown scales covering the body and tail. It is largely terrestrial but can climb trees, always on the lookout for termites and ants nests as it feeds on the adults and their larvae of these insects. When disturbed, it rolls into a ball.
The Lesser Short-nosed Fruit Bat (Cynopterus brachyotis), the dominant fruit bat in the forest, is widely seen in urban areas as well (above-right image by YC Wee). It roosts in trees and under eaves of buildings. It is also known as the Lesser Dog-faced Fruit Bat.
These are just a sample of the many mammals living in the MacRitchie forest. Another reason why we should leave the forest alone.
