There wasn't much action in the chimp enclosure in the mid-afternoon heat, they were mostly lying down and feeding themselves leaves from branches. They live on an island with the house behind. Things warmed up when a youngster ambled along the path by the water. He crossed the bridge to enter the house and then there was an almighty outburst of screeching. Either he fell in or was pushed in by the big ugly fella that was asleep in front of the door. On the platform this chimp roused himself and went to the highest point to see what was going on.
