Zanzibar Red Colobus Monkey (Piliocolobus kirkii) lives in tropical forest across Zanzibar Island. It feeds on leaves and fruits. Its conservation status is Endangered.
Fascinating facts about the Zanzibar Red Colobus Monkey
- Only about 1,600 to 3,000 Zanzibar red colobus remain and their numbers are still decreasing. Roughly half of the individuals live outside any protected area, exposing them to greater threats. The most important refuge is Jozani National Park, which safeguards 25 km² of forest for the species. This limited safe habitat makes the decline especially worrying.
- When feeding on young leaves, some Zanzibar red colobus chew charcoal, a behaviour that helps neutralise phenolic toxins in the foliage of Indian almond and mango trees. Researchers have shown that monkeys are more likely to occupy areas where charcoal deposits coincide with toxin-rich trees. The habit is learned, with mothers passing the practice to their offspring.
- The Zanzibar red colobus avoids ripe fruit because its four-chambered sacculated stomach is specialised for breaking down plant material and cannot process the sugars in mature fruit. Instead, the diet is dominated by leaves, about half of which are young leaves, along with shoots, seeds, flowers and even bark. This dietary restriction shapes its foraging habits across habitats.
- Locals call the Zanzibar red colobus "kima punju", meaning "poison monkey", because its odour is unusually strong. This reputation fuels negative attitudes toward the animal.
