Eastern lowland gorillas as a Congo Safari Attraction in Kahuzi Biega National Park


The Eastern lowland gorilla species are noted to be the largest of all Sub-species of gorillas. They feature a jet black coat that turns into Silver after maturity just like the Mountain gorillas. But the Eastern low land gorillas are differentiated by their short muzzle, large hands, huge body, shorter body and head hair.

The Eastern Lowland gorillas feature the widest altitudinal range compared to other subspecies of gorillas as they thrive in low land, transitional and Mountainous altitudinal tropical forests.  They are noted to be peaceful and social living in groups of five (5) to thirty (30) members featuring the main Alpha male charged with the responsibility of protecting and establishing home range of the group.

The gestation period of a female low land gorilla is around 8½ months and does the breastfeeding for twelve (12) months. The baby gorilla crawls at around 9 weeks and is able to walk after 35 weeks. The young gorillas spend 3 – 4 years with their mothers after and then become independent and mating occurs at 11 or 12 years of age.

The Silverbacks can enter into deadly fighting when different groups meet injuring each other with their canines.  This moment is marked by hooting, rising on their legs, slapping and tearing vegetation, beating their chest with their cupped hands, thumping the ground with their palms and kicking with one leg.
