The tasks of a silverback in zoos: he keeps an eye on everything and everyone most of the time lying down, but also sitting. Another phrase I hate when people call the silverback (or other gorillas) 'that fat one'. In both zoos the silverback is the youngest one of the adults. It's always funny to hear people say 'that old one' about the silverbacks in Artis or Blijdorp. The turning grey with gorillas is slightly suppressed when a young male still lives with his dad. My thought was 'that's not correct, because growing a beard happens to boys no matter if he's still living with his dad or not'. I don't remember where I heard it, but once someone told it can be compared to growing a beard with human males. He can have these grey hairs when he's 11. For instance, when a male moves from a family group at the age of 10 to his own group, he slowly turns grey. It's different with every silverback.Ī lot of people yell out "look that old one" (or words alike) when they see the silverback in a zoo, but the grey hairs don't have anything to do with the age! Because of hormones a male turns grey, as soon as he's the only adult male in a group with females. Sometimes also a big part of their upper back or even shoulders are grey. The western lowland silverbacks really have 'grey pants' to call it (where eastern gorilla silverbacks have only a grey band across their back). He can be recognized by grey hairs on his back and legs and his size. To start: in every family group in zoos there's only one adult, who is the leader. In zoos their tasks are slightly different partly because of the space they have, partly because of the fact that they - whether or not on certain fixed times - get food from their care takers. In the wild he decides what the group does. The silverback in a family group is the leader.
