Mantled Guereza (Colobus guereza) lives in tropical rainforest across Sub-Saharan Africa. It feeds on leaves and fruits. Its conservation status is Least Concern.
Fascinating facts about the Mantled Guereza
- A newborn mantled guereza arrives after just over five months of pregnancy, weighing barely a half-kilogram and covered in pink skin and white fur that darkens by the time it is three to four months old. Females only breed every 16-22 months, so a single mother may raise only one infant at a time. Hunting and habitat loss are threats to the species.
- Male mantled guerezas can tip the scales at up to 13.5 kilograms (30 lb) while females stay under 9.2 kg (20 lb), and their bodies measure about 60 cm from head to rump. Their bulk also makes them a prized target for hunters seeking meat and skin, driving local bushmeat markets.
- At dawn and night, a dominant male launches a thunderous "roar" that can travel up to a mile, broadcasting his presence to rival groups without a physical clash. This long-distance acoustic signal helps space territories across the forest, reducing costly fights and keeping groups apart while they forage on scattered food patches. The roar's reach is a key tool for maintaining social order in the dense canopy.
- Mantled guerezas thrive from lowland forests up to 3,300 m (10,800 ft) altitude and actually become more common in logged or secondary forests than in untouched old-growth. Their ability to digest high-fiber leaves with a specialized multi-chambered stomach lets them exploit the abundant, less defended vegetation that sprouts after disturbance. This flexibility buffers them against moderate habitat change, though complete clearance still wipes out local populations.
- Although the species is listed as Least Concern, hunting pressure remains high: meat fetches $4-9 US and skins are sold for fashion, while in Uganda total forest clearance cut guereza numbers by half in just eight years. One Kenyan subspecies is already Endangered, highlighting that even adaptable species can tumble toward extinction when combined threats intensify.
