19 Facts about Mountain Gorillas-Why are Mountain gorillas endangered?
African Mountain Gorilla
  • The mountain gorillas are the largest and the rarest of all the three species. A male mountain gorilla  can  reach  an  average  of  6  feet  tall  when  standing upright and weigh 180 to 230 kilograms.  Females are smaller with 4 ft. 5 ft. average height while standing and weigh between 70 and 120 kilograms.
  • There  are  three  species  of  gorillas  and  the  mountain  gorilla  is  one  of  the subspecies of Gorillas  that  exist  today; the  western  lowland  gorilla  which occurs  in  West  Africa,  the  Cross  River  gorilla  that  can  be  found  at  the Nigerian/Cameroonian  border  and  Grauer’s  gorilla  or  the  eastern  lowland gorilla in the eastern Democratic Republic of Congo.
  • Males develop a streak of silver hair when they are mature and thus adopt the name silverback. The silvery appearance  is  caused  by  short,  grey  hairs which cover the back and extends to  hips and  upper  thighs. The silver back develops when they are about 15 years of age in the wild.
  • Man is the Gorilla’s closest relative. The nuclear DNA differs by 1.6% between humans and gorillas and there’s 99% likeness between man and a mountain gorilla. Their hands and feet resemble our own so much and interestingly the distance between their big toe and the other toes is very short. Their teeth too very much  resemble  ours,  except  for  the  very  long,  the likeness  is enormous.
  • A mountain gorilla is an endangered species and fewer of them are left today and only inhabit the tropical rainforest ecosystems of Virunga volcanoes of Rwanda,  Zaire and  Uganda  with  Uganda  having  the  largest  last  remaining population of the mountain gorilla.
  • The  population  sizes  and  densities  of  mountain  gorillas  are  difficult  to ascertain for it is not possible to count non-habituated gorillas directly. What researchers   and   wildlife   authorities   do   to   obtain   their   numbers   and population densities is that they make estimate based on the number of nest.As of 2019 the gorillas in Uganda are 459 mountain gorillas.
  • They create transects within the forest over a given distance and a walk along these  transects  and  record all  gorilla  nests  visible until  the  entire  forest  is covered. That’s how the population sizes and densities of non-habituated mountain gorillas are arrived at.
  • The mountain gorillas have shorter arms than the other populations and very long, silky hair, mainly on the arms. Though the hair on their backs is shorter than on most other body parts.
  • Mountain Gorillas are actually shy animals; they live in social groups of 2-35 individuals. These are  called  families  however  a collection of  mountain gorillas  is  called  a  band.    The  silverback who  is  the  dominant  male is  the leader of the group and commands all respect from all other group members, as a leader he’s responsible for the safety and security of the family.
  • Mountain  Gorillas are herbivores and  so  eat  a  lot  of  vegetation  they  feed  on roots, leaves, stems and bamboo. But the gorilla actually loves foraging on bamboo. They also eat soil occasionally. It is believed that the soil contains minerals that maybe missing in their normal diet, or the minerals neutralize poisonous substances in their food.
  • Gorillas live primarily on the ground. They spend only 5–20% of the day in trees and when they climb, they mainly do eat fruits and leaves on higher branches.
  • Mountain gorillas unlike other species occasionally climb beyond the tree line. The tree line is the altitude above which trees do not grow.
  • Mountain Gorillas leave their sleeping sites very early in the morning, feed and take rest around noon. In the afternoon they forage again before resting at night. The rest periods are for Social contacts, the females will be breast feeding and the  older  gorillas  will  play  a  little  bit  while  the  leader  watches over. Occasionally the silverback participates and plays with the young ones.
  • The sleeping nests are made using the branches of bushes and other plants. The animals pull the branches into the center and plants are bent in to form a rim around the nest.
  • Mountain gorillas can never sleep in the same nest for more than one night. Every evening the gorillas construct a new nest, each animal constructs its own nest and it’s only the infant gorillas that share a nest with their mothers.
  • Man is the mountain Gorilla’s main threat, apart from you and I, gorillas do not really have enemies. And when there’s a threat, Silverback male(s) responds immediately  by  giving  off  an  intense  vocalization,  gnashes  the canine teeth and beats the chest.
  • The other group members drive the group away from the source of danger. The dominant male is entirely responsible for defending his family. There can be a show of strength when two mountain gorilla groups meet especially between the leading silverbacks.
  • A mountain gorilla that is under great care can survive up to 53 years in a zoo; however one in the wild can live up to 35 years. Like in humans, old mountain gorillas are susceptible  to  certain  illnesses  as  well  as  body  and  muscular weaknesses.
  • They suffer from the loss of teeth and find difficulty in feeding. The other group members take the responsibility of nursing and looking after the aged members.

Mountain Gorilla Most Rare Facts

  • A Gorilla is one of the largest animals with very small sexual organs. Its testes and penis are as small as 3 cm long when erect averagely whereas its testes weigh between 30–35 g. whereas an average man’s penis 12.9cm long when erect and 10-15 grams of testicle weight.
  • The gestation period of a gorilla is about 257 days on average. It is also known that Twin births occur among gorillas as often as in humans. A new-born baby gorilla can weigh up to 2.4 Kgs on average.
  • Gorillas mainly use vocalizations for communication. This is because they live in thick forests and they use the vocalizations to trace group members they cannot see and can accompany social interactions.
  • On average, an adult silverback can   make   eight vocalizations   per   hour,   most   often   during travelling.
  • A  gorilla  male  achieves  his  high-ranking  position  not  only  because  of  his strength,  which  he  proves  when  fighting  against  competitors,  but  also because  of  his  experience  and  abilities.
  • If the females notice that their silverback is too inexperienced, they will transfer to another group where the silverback is more experienced especially in handling human enemies.
