Gorilla Snacking Songs: Humming in the Jungle

One of the most fascinating facts about mountain gorillas is that the hum while eating, and just like humans when savoring a favorite meal, mountain gorillas sing contentedly as they enjoy their forest buffet. This fascinating behavior was first filmed in the documentary series “Spy in the wild” where a robotic “spy gorilla” recorded this rare moment in the wild.
During her tremendous research in the Virunga Forest, renowned primatologist Dian Fossey identified at least 16 different vocalizations in gorillas, ranging from the aggressive roar of a silverback to the soft belch of a relaxed group. These sound convey a wide range of emotions, from happiness and calm to fear and alertness. Interestingly, if you hear gorillas blenching during your gorilla trekking in Uganda and Rwanda. It usually means they are at ease and accepting of your presence in their territory.
Understanding Gorilla Vocalizations
Gorilla vocalizations are very important to how these endangered primates communicate within dense rainforest habitats. Since in the forest is low due to the thick vegetation cover, sounds like grunts, hoots, and hums help gorillas stay connected. The food – related humming, or snacking songs is one of the most charming aspects of their behavior and has intrigued scientists as a potential link to the evolution of human speech.
These melodic sounds usually occur while eating or in anticipation of food. They may serve to signal enjoyment, promote group cohesion, or even establish eating rights within the troop. Considering gorillas share 98% of their DNA with humans, it is not surprising that we recognized something familiar in their behavior.
Mountain Gorilla Conservation: A Rare Success
The gorilla census carried out in 2019 brought encouraging news of an increase in the population of mountain gorillas in Uganda, Rwanda and DR.Congo to over 1,060 individuals. This growth is a testament to intensive conservation efforts and the positive impact of gorilla trekking tourism.
Tourism revenue has helped fund anti-poaching patrols, habitat preservation, and community engagement projects. Local communities benefit economically from the presence of tourists, which provides a powerful incentive to protect these endangered animals and their forest homes.
