The hair on the back of the males will turn silver-gray with age, earning them the name “silverback”. They have black skin and coarse hair ranging in color from brown to gray. What we learn by working with these three males will aid other zoos when forming additional bachelor groups.ĭescription Western lowland gorillas are large, muscular primates. Since then, managing a bachelor group of gorillas has been an important part of the Gorilla SSP captive management plan. In captivity, we have to help them out in that bachelor group establishment. In the 1980s the Gorilla Species Survival Plan (SSP) had to provide companions for these male offspring and also find a way to optimize the use of limited captive space. Males stand between 1.69 to 1. Since gorillas are very social animals, these juvenile males form bachelor groups temporarily. (331 and 461 lb) based on four males, females of 76 kilograms (168 lb) although this had a small sample size. So it is estimated that, at about 6 to 10 years of age, those males are driven out or leave on their own. Some of those offspring will eventually mature into reproductive males that could challenge the status of the resident silverback. Typically, gorillas in the wild live in large family units (a single silverback with several females and offspring). Visitors often ask why there are no females. Since Pende has matured into a silverback, he has been less interested in the power struggle. Researchers determine these weights by measuring their bones, muscles, and fat content through modern medical technologies. Now, Kongo is most dominant due to his size. The actual weight of Silverback Gorillas ranges significantly, from 300 to 500 pounds for adult males and up to 200 pounds for females. Chip became a silverback first and for a while was the most dominant. The hair on the back of these males has either turned or is turning silver-gray with age, earning them the name “silverback”. In the winter months, the gorillas can been seen in the habitat’s indoor viewing area. Half-brothers Chipua (born in 1996), Pendeka (born in 1998) and Kongo-Mbeli (born in 1998) arrived at the Detroit Zoo in 2003 and can be seen at the Great Apes of Harambee, a 4-acre habitat that is also home to chimpanzees.
