Chimps use branch as ladder to escape Belfast zoo enclosure Chimpanzees have used a branch to escape from their enclosure at Belfastzoo in the second breach by animals in recent weeks. They took advantage of damage caused by stormy weather to stage a breakout, which visitors caught on film. It comes after a red panda cub called Amber was found in a garden less than a mile from the zoo after it escaped from its enclosure last month. The latest bid for freedom was made by chimps who used a branch as a makeshift ladder and scaled high walls surrounding their pen on Saturday. I love monkey stories.Maybe we need to re-evaluate their place in the food chain ? They show vision,intelligence and the ability to work for the common good. They should certainly rank higher than right wingers.
