Mountain Gorillas: Everything You Need to Know

In the dense rainforests of East Africa, a critically endangered species of gorilla known as the mountain gorilla can be found. With only around 1,000 individuals left in the wild, these majestic primates are under threat…but from their highly specialized diet to their complex social system, the mountain gorillas are a fascinating species that is vital to the balance of the ecosystems they call home.

The mountain gorilla, one of the largest and most endangered primates in the world, is native to the forests of East Africa. Known for their gentle demeanor and impressive size, these great apes are an incredible species that have been the focus of conservation efforts for many years.

Mountain Gorilla Habitat and Diet

Mountain gorillas are found only in a small region of East Africa, specifically in the high-altitude forests of the Virunga Massif, which straddles the borders of Rwanda, Uganda, and the Democratic Republic of the Congo, as well as in Uganda’s Bwindi Impenetrable Forest. These rainforests are characterized by cool temperatures, dense vegetation, and a wide variety of plant and animal species.

Mountain gorillas are primarily herbivores and subsist on a diet of leaves, stems, fruit, and flowers. They are known to consume over 100 plant species in their natural habitats, including bamboo shoots, nettles, and celery-like stalks of the lobelia plant. Gorillas spend a significant portion of their day foraging for food, and their diet varies seasonally depending on the availability of different plant species.


Mountain gorillas are known for their complex social structures and behaviors. They live in groups, known as troops, led by a dominant silverback male. The troop is made up of several adult females and their offspring, with the silverback responsible for protecting his family members and leading them to food sources.

The social structure within the troop is hierarchical, with the silverback male at the top. He is responsible for making all major decisions and ensuring the safety and well-being of his troop. The females within the troop are usually related to each other, with a few unrelated females joining the group occasionally.

Young gorillas within the troop are often referred to as infants, juveniles, or blackbacks. Infants are born weighing only 3-4 pounds and are completely dependent on their mothers for the first few years of their lives. Juveniles are weaned at around 3 years of age but remain with their mothers until they reach sexual maturity at around 8-10 years old. Blackbacks are young males who have not yet developed the silverback’s signature silver patch but have left their family units to avoid potential competition with the dominant male.

Family Units

The family units within the mountain gorilla troop are complex and constantly changing. Silverbacks will often form new troops by taking over an existing group, and they may also allow unrelated females to join their group. Females will occasionally leave their troop to join another, often to avoid the attention of an aggressive male.

Within the troop, the females are responsible for raising their young, foraging for food, and grooming each other. The silverback male is responsible for protecting his family members, leading them to food sources, and engaging in displays of dominance to deter potential rivals.


Mountain gorillas communicate with each other through a variety of vocalizations and body language. They make a range of sounds, including grunts, hoots, and roars, which they use to express a wide range of emotions, from excitement to aggression.

Body language is also an important part of communication among mountain gorillas. They use displays of dominance, such as chest-beating and charging, to assert their position within the troop. They also groom each other, which helps to maintain social bonds and hygiene, as well as to remove parasites and ticks from each other’s fur.


Mountain gorillas are one of the most endangered primate species in the world. In the 1970s and 1980s, their population declined rapidly due to habitat destruction, poaching, and civil unrest in the region. However, through the efforts of dedicated conservationists and organizations, the population has started to recover in recent years.

Today, there are an estimated 1,063 mountain gorillas left in the wild, according to the most recent survey conducted in 2018. This is a significant increase from the 786 individuals that were counted in the last survey conducted in 2010. Despite this progress, mountain gorillas still face a number of threats to their survival.

Habitat loss and degradation continue to be major threats to the species, with deforestation, agriculture, and development leading to the fragmentation and destruction of their forest habitats. Poaching for the illegal wildlife trade and habitat encroachment by people also pose significant risks to their survival. Additionally, mountain gorillas are susceptible to a number of diseases that can be transmitted by humans, which makes conservation efforts challenging.

Efforts to conserve mountain gorillas have focused on a variety of strategies, including habitat protection, anti-poaching efforts, and veterinary care. The creation of protected areas, such as Bwindi National Park in Uganda and Volcanoes National Park in Rwandahas been a critical part of the conservation effort. These areas provide a safe haven for the gorillas and allow researchers and conservationists to monitor and study their behavior and health.

Tourism has also played an important role in the conservation of mountain gorillas. Gorilla trekking, where visitors can see the animals in their natural habitat, has become a popular activity in East Africa. This has not only provided an economic incentive for local communities to protect the gorillas and their habitats but also helps to raise awareness about the importance of conservation efforts.

By continuing to protect their habitats, combat poaching, and promote responsible tourism, we can ensure that these magnificent animals continue to thrive in the wild.

Where to See Mountain Gorillas in the Wild

Rwanda and Uganda are two of the best places in the world to see mountain gorillas in their natural habitat.  In Uganda, Bwindi Impenetrable National Park is a popular destination for gorilla trekking. With over 400 gorillas in the park, visitors have a good chance of seeing these magnificent animals up close.  Mgahinga Gorilla National Park in Uganda also offers gorilla trekking, with one habituated family in the park.

In Rwanda, Volcanoes National Park is home to a number of habituated gorilla groups that can be visited by tourists. Gorilla trekking is the main attraction here, and visitors can expect to hike through the park’s lush forests to find the gorillas. Gorilla trekking permits are required in both countries and can be obtained through the national park authorities or through a licensed tour operator.
