Unlike their eastern cousins, western gorillas are hunted for bushmeat, and in recent years the spread of the Ebola virus has devastated the gorilla population. But as the logging industry engulfs the forest, bringing roads, hunters and disease, the western lowland gorillas’ long-term future has been thrown into uncertainty. Until recently, conservationists were less concerned about the long-term future of the western lowland gorilla as their vast forest home created a natural boundary between them and their human neighbours. Habitat loss, hunting for bushmeat, disease (especially the Ebola virus), logging, mining Widespread throughout west and central Africa They also eat leaves, shoots, bark, ants and other insects. Like all gorillas, they are largely herbivorous, but western gorillas are particularly fond of fruit, which makes up most of their diet when available. Western lowland gorillas live in family groups led by a dominant silverback, but unlike eastern gorillas, the group will often split up during the day, coming back together at night to nest. ![]() ![]() They often have much redder or greyer fur, adult males have striking chestnut fur on their head and neck, and the characteristic fur on their back extends further down their thighs giving them a more full-bodied silver look. Western lowland gorillas are smaller than their eastern cousins – although adult males can still weigh up to 180kg (28st 4lb). That’s when all male gorillas develop their characteristic silver-grey fur.Democratic Republic of Congo, Gabon, Cameroon, Angola, Equatorial Guinea, Central African Republic Their weight doubles between the ages of twelve and eighteen. They only finish maturing, however, by the time they are about eighteen. Males become sexually mature relatively young. After that they must abide by all the rules and the hierarchy in the group. The white tuft means something like: “I’m young so I can still do whatever I please.” The white tuft disappears when gorillas reach puberty, by age five or six. This tuft is a clear signal to the other members of the group to treat the young gorilla kindly. During the first years of their life, you can recognise gorilla young by the tuft of white hair on their buttocks. Born May 22, 1998, at the Gladys Porter Zoo in Brownsville, Texas. Young gorillas suckle milk from their mother for four or five years. Mothers initially carry their infants on their belly and later on their back or on an arm or leg. Gorilla babies hold on tightly to their mother’s fur using their hands and feet. The newly born infant is very small and only weighs two kilos. The new mother then rests for a few hours and goes out with the group again the very next day. They have their first baby when they are about ten. This sound is amplified by the hollow space in its chest and can be heard as far as two kilometres away! By the way, gorillas beat their chests for other reasons too, for example when they want to play, challenge each other or boast.įemale gorillas become fertile when they are about eight years old. He then runs towards the other animal, tearing up bushes and trees on the way to demonstrate his strength and then does a drum roll by beating his chest with his flat hands. Which he might do to intimidate another silverback. ![]() It’s especially impressive to see a silverback beating his chest. But sometimes he hits a female to correct her. If the females are at odds with each other, he usually lets them sort it out themselves. Sometimes the silverback must act, though. All he has to do to control the group is adopt a certain posture, or look directly at another individual. Often the silverback doesn’t even need this type of communication. They do this, for example, when they lose sight of each other, or feel threatened or get into an argument. But gorillas are also capable of screaming and roaring loudly. They often produce a soft, humming sound which tells other individuals that they are contented. Gorillas are very quiet and friendly animals.
