Mjukuu and Tiny were at the entrance to the runway, so its either her or Zaire, and based on what her age looks like I\'m going with the former, though if I\'m wrong corrections are welcome. 24th February 2011.
As correctly identified by Tinkywinky, this is 'Zaire'.
Despite what they said originally about the potential dangers of introducing a new male to an unrelated baby, I can't see them keeping them seperate like this for several years to come. I think perhaps they may try to introduce 'Kesho' once the baby is a bit bigger/stronger. I would be very surprised if he was aggressive anyway as he's already familiar with the group now.
