Emma may be approaching middle age, for a Sumatran orang, but she put on a real show for the public. Climbing in and out of her sack on the highest ropes and then descending to the ground to do an impressive series of forward rolls with sack. She then took this quite moment to relax. Her keeper thought she might be a bit stiff next morning. South orang exhibit, Islands, Chester, 26th July 2016.
