Apart from humans, the long-tailed macaque is probably the most successful primate species in Southeast Asia. It can be found in a wide variety of habitats: primary lowland rainforests, disturbed and secondary rainforests, as well as riverine and coastal forests of nipa palm and mangrove. They are opportunistic omnivores, eating a variety of plants, animals, and other materials, although fruits and seeds make up the majority of their dietary intake. When they inhabit disturbed areas near human settlement, they quickly learn to raid gardens and crops as well as beg for food from humans (don’t feed them!)
Long-tailed macaques live in groups that could be as small as six or as large as fifty. They also exhibit a strong dominance hierarchy, with the highest ranking male having the highest access to reproductive females. These primates are often seen in the forests of El Nido, and hikes along El Nido’s trails are often incomplete without groups of these inquisitive macaques showing up.
