When you fancy forty winks an alfresco nap is just the answer as chimp, Fanny, discovered when she swopped her comfy straw bed for a plastic play tyre out in the paddock.
Head of Lower Primates, Nicola Wright managed to grab her camera and snap the dozing chimp curled up on the tyre.
Nicola said: “It didn’t look that comfy although it must have been as Fanny curled up in a ball and snoozed for quite a while. It was quite an amusing sight.”
