Does this mean the baby will be permanently separated? Or will they attempt to reintroduce him to mum when he hopefully recovers? I assume the longer they are separated the chances of a successful reintroduction dwindles.
The longer the two are separated, the more challenging a reintroduction will be. At other zoos, it's been successful once the infant is around two years old - but that's been under docile silverbacks. There's no guarantee Kisane would be as tolerant.
If reintroduction is not possible, they should allow Kipenzi to conceive again. She could easily deliver a subsequent infant within 12 months - allowing this infant to be socialised one on one with a peer in the juvenile stages.
