Baby Gorillas: Birth and Early Life

Slow breeders whose babies shape the survival of the species.

Mountain gorillas reproduce slowly. A female typically gives birth to one infant after a gestation of about eight and a half months, and may raise only a few young in her lifetime. This slow pace makes protecting every group important.

Quick Facts

Gestation

About 8.5 months.

Birth interval

Roughly four years.

Weaning

Around two to three years.

Maturity

Females from about 8 to 10 years.

Infancy

Newborns weigh little and cling to their mothers. They ride on the back from around five months and start to explore by one year.

Family dynamics

The silverback tolerates and protects the group’s infants. Females may leave to join other groups when they mature.

Why it matters

Births count toward recovering the population. Trekking fees fund rangers and vets who protect infants.
