@Vornaskotti - I was at Howlett's Animal Park on Saturday. They have a lot of Gorillas and it was amazing to watch their behaviour. One of the big silver backs was sat at the front of the enclosure watching the spectators. He went off and came back with a stick that he passed though the mesh to one of the spectators, then took it back again and carefully stirpped the bark from one end and passed it back out of the enclosure. They also have the largest herd of elephants in the UK and it was great to watch their behaviour.
