According to the study of mountain gorillas, there are 5 major movement mechanisms of gorillas in Rwanda

Tree-climbing

Gorillas are mostly known to live primarily on the ground however they take some time while in the trees for about  5-20% of the day. Mountain gorillas love to play or harvest fruits from the trees through one of the 5 major movement mechanisms of gorillas (tree climbing). These apes make use of all their four limbs to grasp when climbing trees in support with strong claws and big toes. A big percentage of young gorillas spend more time in the trees than adults in trees and like to play there in the big trees with many branches. Unfortunately, adult Virunga gorillas are very rare to climb trees as well as silverback males due to their heavy weight.

Western lowland gorillas are the commonest and spend considerably much time in the trees.  However, they can climb if the trees have fruits and as long as the tree branches can support their weight.

Bipedaling/walking

Gorillas are highly known to move on both the feet and hands but at times, they walk on two legs. This movement mechanism is much more common in juveniles or even adults while carrying infants or manipulating food and trying to pay attention to something at a distance. However, adults walk but it’s on a rare occasion, and may do it for a few steps. The adult gorillas walk in case they are going to beat their chests and engage in an encounter.

Brachiate/ arm swinging

The body of the gorilla is supported under the forelimb.  This is due to the support of longer arms than legs, a short stable lumbar spine, long curved fingers, and reduced thumbs. The process of brachiation involves jumping from one tree branch to another tree branch while wandering in the forests looking for food especially, the abundance of food sources. Luckily enough, gorillas eat many different types of plants which helps them not to travel far distances looking for food. In other words, gorillas travel less than one mile per day on average than humans.

Quadrupedal

At times this mechanism is referred to as knuckle-walking, in which the forelimbs hold the fingers in a partially flexed posture that allows body weight to press down on the ground through the knuckles this also prevents it from stumbling. It also implies that they walk on top of their knuckles rather than putting all their weight on their palms. Of all the 5 major movement mechanisms in gorillas, knuckle-walking is the most famous one applied by the majority.

Locomotion among infant gorillas.

Gorilla babies are almost like human babies, they need a lot of support in everything they engage in when they are born.  In the first days of birth, the gorilla mother lays the baby on her stomach as she supports it with one arm while walking (on three legs). As the days go by, the baby gorilla gains some strength to grasp the mother. Finally, when the infants start climbing the mother’s back, it walks normally on the four limbs (quadrupedally). They start enjoying the short rides on their siblings in case they ain’t the firstborn. On a rare basis, mothers practice leg carrying when the infant is to be carried and sit on the mother’s back.

Where are mountain gorillas located in Rwanda?

Mountain gorillas are among the famous apes in Rwanda and the highly visited.  Tourists visit Rwanda for gorilla trekking and to study their social behaviors. These endangered subspecies are protected within Volcanoes National Park in Rwanda. The park is open for both residents and non-residents as long as you own a gorilla permit for you to observe the 5 major movement mechanisms in Rwanda.
