Troops also include several other young males, some females, and their offspring. Troops are led by one dominant, older adult male, often called a silverback because of the swath of silver hair that adorns his otherwise dark fur. Gorillas can climb trees, but they’re usually found on the ground in communities-known as troops-of up to 30 individuals. They eat roots, shoots, fruit, wild celery, and tree bark and pulp. These gorillas live in thick tropical rainforests, where they find plenty of food for their vegetarian diet. Habitat and dietĪs the most widespread gorilla subspecies, the western lowland gorilla can be found across more than 270,000 square miles of central and West Africa-including Cameroon, Central African Republic, the Democratic Republic of the Congo, Equatorial Guinea, Gabon, Angola, and the Republic of the Congo. Like their cousins, western lowland gorillas are endangered and face the loss of their habitat. Infants have a tuft of white hair on their backsides, and older gorillas may get streaks of silver in their hair. Western lowland gorillas have shorter black-brown hair, longer arms, and a more prominent ridge along their brow. Western lowland gorillas are the smallest of the four gorilla subspecies, which also include the Cross River gorillas, Grauer’s gorillas, and mountain gorillas. Of course, they can be violent, not just when faced with the threat of predators, but also when it comes to maintaining their status at the head of a group and ensuring the infants they have fathered thrive ahead of the offspring of others.Current Population Trend: Decreasing What is the western lowland gorilla? So, you see, silverbacks aren’t the violent, terrifying brutes they are often presented as. They will also teach young males how to fight and even happily serve as playmates or even passive climbing frames for excitable infants – a site which never fails to shock visitors to the National Parks. Silverbacks are incredibly gentle and often serve as mentors for youngsters, teaching them what foods to eat and how to make their nests for sleeping. Why is this? Well, we now believe that, in many cases, female gorillas appreciate more than just brute strength. What’s more, only some of the females in his group have been tempted away by these younger, stronger upstarts, with others preferring to stay loyal. He continues to lead his group, even though younger, stronger males have challenged him and even beaten him in fights over recent years. In the Virunga National Park, for example, there is an aging silverback called Humba. As you might imagine, a silverback rarely listens to the opinions of others – any younger male or cheeky youngster wanting to go their own way is quickly brought back into line!įor me, however, the one thing that always fascinates me about silverback is their gentleness, not just their strength. In fact, a silverback can lead their group for up to five miles a day in search of a lush patch of wild celery or nettles or a safe, secluded place to spend the night. This means they will decide where a group will make their day or night nests to sleep, plus it also means that they lead the search for food. As the leader of a group, they are also the main decision makers. If beating their chests loudly or stamping their feet in a show of strength doesn’t work, then a silverback will fight, often at great risk to himself, using his huge arms and teeth.īut a silverback does much more than guard and fight. In the jungles of Central Africa this can mean the threat of wild leopards or even other single male gorillas looking to take over a family. These big muscles aren’t just for show! A key role of the silverback is to serve as the protector of his group from any potential dangers. He will weigh around 350 pounds, twice the average weight of an adult human male, with much of this made up of the huge muscles in his legs and chest. Let’s put it this way: they are huge! A typical adult mountain gorilla male will be around six feet tall when he stands on his back legs – a full foot taller than an adult female. So let me explain a little.Ībove all, what distinguishes a silverback from the rest of his group is his size and strength. But few people realise just how fascinating and complex the life and role of a silverback really is. Now, most of you will know that the silverback is the adult male that leads the group, named after the distinctive silver hair that starts growing on their backs from the age of around 11 or 12. But, I must admit, one thing awes me more than anything: the sight of a powerful silverback. The sight of our cousins in their native habitat never fails to inspire me. Over that time, I have been into the forests of my native DR Congo countless times, usually to observe the mountain gorillas you help to protect. I’ve been working in gorilla conservation for almost 20 years.
