Silverback mountain gorillas can measure up to 1.52. The father interacts little with his descendants, his role being, in particular, to defend his family against the attacks of other silverbacks. Adult female gorillas are shorter than the males reaching an average height of 1.25 to 1.5 meters tall. The young remain on the mother’s back for about ten months and complete weaning takes place after about four years. Their reproductive rate is low, the female gives birth to one baby gorilla per year, especially since twins are rare and the gestation period is about 9 months. The life expectancy of the western gorilla in nature is around 45 years. When the males start to have a more developed silver back they also leave their group of origin, become solitary and start looking for other family groups to convince females to join them and form a new group.
Females leave their native group at the time of their sexual maturity to join other silverbacks to reproduce. Silverback Gorilla Characteristics Silverback gorillas are one of the most awe-inspiring animals to observe in the wild. The social structure of the western gorilla is made up of a silverback, adult females generally between 3 and 7 and their offspring. Unlike eastern gorillas, only one silverback male is tolerated and present per group. Maintaining group cohesion is much more difficult when searching for food, especially during the rainy season when fruits are abundant, as some move further away from the group. These groups are typically composed of several, usually unrelated, adult females, their offspring and a single silverback male. Unlike chimpanzees, wild gorillas do not use many tools and they can cover long distances searching for food. In contrast, female mountain gorillas weigh 90kg, and measure up to 150cm (4’9). An average silverback gorilla can weigh up to 180kg (that’s almost 30 stone), and measure 170cm (over 5’5) tall on all fours. In rainy seasons, the Gorilla builds its nest directly high up in the trees. They’re one of the biggest, most powerful living primates. During the dry season, the nests are simply constructed but can become more elaborate depending on the degree of rain and consist of cool branches that isolates the moisture from the soil.
In the evenings, they build their nests mainly on the ground next to the dominant male. The western gorilla groups are very cohesive, all members remain at a distance allowing auditory contact with the dominant male. The female reaches half of the male size and reproduces for the first time between 8 years and 11 years, much earlier than for the male.
Are silverback gorillas male or female Patch#
The male completely develops the silver color of his back around the age of 18. A silverback is an adult male gorilla, typically more than 12 years of age and named for the distinctive patch of silver hair on his back. The western gorilla is physically smaller than the eastern gorilla.
