The Eastern Gorilla (Gorilla beringei) is a large primate species native to the mountainous regions of Central and East Africa. It is one of two gorilla species, the other being the Western Gorilla (Gorilla gorilla), and is classified into two subspecies: the Grauer’s Gorilla (Gorilla beringei graueri) and the Mountain Gorilla (Gorilla beringei beringei).
The Eastern Gorilla has been listed as Endangered by the International Union for Conservation of Nature (IUCN) due to habitat loss, poaching, disease, and civil unrest in its range countries.
Eastern Gorillas are known for their massive size, with adult males weighing up to 220 kilograms and standing over six feet tall when fully erect. They have dark black hair covering most of their body except for their faces, palms, and soles of their feet.
These primates live in groups called troops led by an alpha male who dominates mating opportunities within the group. Their diet consists mainly of vegetation such as leaves, stems, fruit, bark, and bamboo shoots.
In recent years, conservation efforts have increased to protect this critically endangered species from extinction.
Classification And Subspecies
The eastern gorilla (Gorilla beringei) is a species of great ape that inhabits the mountainous forests of central and east Africa. They are divided into two subspecies: the Grauer’s gorilla (Gorilla beringei graueri) and the mountain gorilla (Gorilla beringei beringei).
The former can be found in the Democratic Republic of Congo, while the latter resides in Rwanda, Uganda, and the Democratic Republic of Congo. Both subspecies share similar physical features such as black fur covering their bodies, broad chests, muscular arms, and dark eyes.
Despite being classified as one species with two subspecies, genetic studies have shown significant differences between Grauer’s gorillas and mountain gorillas. In fact, they may have diverged from each other around 400,000 years ago.
Furthermore, within each subspecies exists considerable genetic diversity due to their fragmented habitat ranges caused by human activities like deforestation and mining. This poses a threat to their conservation status because it reduces gene flow between populations which leads to increased susceptibility to diseases and reduced ability to adapt to environmental changes.

Threats And Conservation Status
Having discussed the classification and subspecies of the eastern gorilla, it is important to examine its current threats and conservation status.
Poaching and habitat loss are considered as major factors that have contributed to the decline in population numbers of this species.
The Eastern Gorillas’ habitats are located in countries such as Uganda, Rwanda, Democratic Republic of Congo (DRC), which have been plagued by civil unrests over the years. These conflicts lead to deforestation for timber production and mining activities causing a significant reduction in their natural habitats.
Additionally, poachers target these animals for bushmeat trade or capture them alive for illegal wildlife trade, making them endangered species with an estimated 5% decline per year in population trends.
Despite some efforts made towards conserving their populations through law enforcement initiatives and protected areas management plans, there still exists a need for increased protection measures to ensure their survival.
Population trends show that without swift action taken against poaching and habitat destruction, we risk losing these gentle giants forever.
The distribution range of Eastern Gorillas has also decreased by more than 50%, leaving only scattered groups throughout their native lands.
Therefore, it’s crucial to continue monitoring population sizes across different landscapes while enforcing policies aimed at protecting remaining forested regions where these primates can thrive freely.
Ultimately, maintaining viable populations of Eastern Gorillas will require collaborative partnerships among governments, non-governmental organizations (NGOs), researchers, local communities living around protected areas sites who play a vital role in both implementing effective conservation strategies and creating awareness about the plight facing this critically endangered animal species.
Physical Characteristics And Size
The Eastern Gorilla (Gorilla beringei) is the largest living primate on earth, with males weighing up to 250 kilograms and standing at a height of 1.8 meters. Females are smaller than males, with an average weight ranging from 100-150 kilograms and a height of about 1.5 meters.
The fur on their body ranges from black to brownish-gray, with older gorillas having silver hair on their back. Habitat preferences play a critical role in determining the size and physical characteristics of Eastern Gorillas. They prefer high-altitude montane forests that offer them cover and food sources such as fruits, leaves, bamboo shoots, bark, flowers, insects, etc.
Despite being strong and muscular creatures, eastern gorillas are herbivores. Males have larger canines than females but don’t use them aggressively towards each other unless it’s during fights over dominance or mating rights.
Their reproductive cycle is slow compared to other primates; females give birth once every four years after gestating for approximately eight months. Newborn gorillas weigh about two kilograms at birth and rely entirely on their mothers for survival until they’re weaned off milk between three to five years old.
As they age, male gorillas develop gray hair patches around their temples due to hormonal changes similar to human beings experiencing baldness. Eastern Gorillas’ unique biological features make them fascinating animals worth studying further by researchers worldwide.
Social Structure And Behavior
Having explored the physical characteristics and size of the eastern gorilla, it is now time to delve into their social structure and behavior. While these majestic primates are known for their impressive stature and strength, they also exhibit complex social relationships that have fascinated researchers for decades.
One of the most notable aspects of eastern gorilla society is their dominance hierarchy. Within a group, there is typically one dominant silverback male who holds sway over all other members. However, this position must be constantly reinforced through displays of aggression and intimidation towards subordinate males.
Interestingly, female gorillas often play an important role in maintaining this hierarchy by choosing to mate with the dominant male and assisting him in confrontations with rivals. In addition to this hierarchical system, eastern gorillas also engage in intricate grooming behaviors as a means of reinforcing bonds within groups.
Reproductive behavior is another fascinating aspect of eastern gorilla life. Females only give birth every four years or so, which makes successful reproduction crucial for the survival of the species. During mating season, dominant males will perform elaborate displays to attract females while simultaneously fending off rival suitors.
Once pregnant, females will carry offspring for nearly nine months before giving birth to a single infant. The mother-child bond is incredibly strong in eastern gorillas; mothers are fiercely protective of their young and remain close at hand for several years after birth until offspring become independent adults themselves.
Diet And Feeding Habits
The Eastern Gorilla’s diet is mainly herbivorous, consisting of vegetation such as leaves, fruits, and shoots. They are known to have a preference for bamboo shoots in their diet due to its high nutritional content.
The gorillas use a combination of different foraging techniques when feeding, including browsing on low-hanging vegetation or climbing trees to access higher foliage.
Their preferred foods vary depending on the season; during dry seasons where food may be scarce, they tend to feed on more bark and stems than during wetter months.
Additionally, they will occasionally consume small insects or grubs when available but this makes up only a small portion of their overall diet.
Eastern Gorillas have adapted well to survive in their natural habitat through their specialized feeding behaviors and preferences. By understanding these dietary needs, we can better appreciate the role that these magnificent creatures play within their ecosystem as well as develop effective conservation strategies for protecting them from threats such as habitat loss and poaching.
Efforts To Protect The Species
The eastern gorilla’s diet and feeding habits have been extensively studied, as they play a crucial role in the species’ survival. These primates are primarily herbivores, with their diets consisting of leaves, stems, bark, fruits, flowers, and seeds. They also consume insects and occasionally small mammals.
Eastern gorillas exhibit complex foraging behaviors that vary depending on food availability and distribution. For example, when fruit is scarce during dry seasons, they resort to eating more fibrous vegetation.
Efforts to protect the eastern gorilla involve community involvement and ecotourism initiatives. Local communities living near these primates’ habitats have been actively involved in conservation efforts through education programs aimed at raising awareness about the importance of protecting this endangered species.
Ecotourism initiatives have also played a significant role by generating revenue for local communities while promoting responsible tourism practices that minimize negative impacts on the environment and wildlife. This approach has not only helped preserve the eastern gorilla’s habitat but has also contributed to local livelihoods and economic development.
Conclusion
The eastern gorilla is a critically endangered species with two subspecies: the Grauer’s gorilla and the mountain gorilla.
Habitat loss, poaching, and disease are among the biggest threats to these primates’ survival.
The International Union for Conservation of Nature (IUCN) estimates that there are only 3,800 individual Grauer’s gorillas left in the wild, making them one of Africa’s rarest large mammals.
Eastern gorillas have black fur and distinctive faces with pronounced brow ridges.
Males can weigh up to 400 pounds and stand over five feet tall on average, while females typically weigh around half as much.
These intelligent apes form complex social groups led by dominant males called silverbacks.
They communicate through vocalizations, body language, and facial expressions.
Conservation organizations such as the Dian Fossey Gorilla Fund International work tirelessly to protect this magnificent species from extinction.
However, despite their best efforts, it may be too late for some populations of eastern gorillas already decimated by habitat destruction and hunting.
For example, between 1994-2018 alone, Grauer’s gorilla numbers dropped by an alarming 77%.
It is crucial that we continue our conservation efforts if we want to save these incredible animals from disappearing forever.
