How is it possible that our youngest Bornean orangutan, Redd, is already celebrating his fifth birthday? It seems like yesterday Batang was carrying him on her shoulders across the O-Line because he was too young to climb the cables on his own.

Now, Redd is the master of the O-Line, eliciting gasps from staff and visitors alike as he hangs upside-down from his feet, tightrope walks across the cables or leaps from the cables onto the platform. Orangutans are skillful climbers; often, they are described as having four hands rather than what they actually have—two hands and two feet. Still, those of us who observe his O-Line travels (and are not quite as dexterous as orangutans) would breathe easier if he would hold on with more than one of his hands!
