Eastern Gorilla Facts

Gorilla Beringei

  • Eastern gorillas live in stable and cohesive family groups led by a dominant silverback male.
  • They tend to have larger groups than their western relatives, comprising up to 35 individuals.
  • Males defend their females and young by using their size in intimidating displays of attacks and breast thrusts.
  • They are diurnal, but most foraging occurs in the morning and late afternoon. At night, they build nests by folding in vegetation, typically on the ground.
  • These primates are essential in structuring plant communities as they feed on vegetation.
