You can thank my sweet husband for finding this gem for you in the Guardian: Animal magic.
It was a courteous encounter, like Stanley meeting Livingstone. In Deep Jungle (a gem on the rubbish tip of ITV1), Roman Dial was hanging about in the canopy of the Borneo jungle. Sometimes he is up there for weeks at a time mapping the density of the jungle with lasers and a global positioning system linked to a computer. The animals are only of incidental interest to him.
Suddenly an ape offered him a sprig of leaves. He said: "Look at that! A gift!" and took it. There was a rather pointed pause on the ape's part. "Oh, now you want something back?" he said and returned it. High in the forest canopy they stretched towards each other, one arm hairy, one bare. He tickled its palm with pale fingers. It hooked a long, strong finger and touched him.
It looked like The Creation of Adam.
Deep Jungle is full of curious creatures, most of them wearing shorts. Wherever there is a jungle, you will find another naturalist being nosy. I was particularly taken with Kim Bostwick, who has taught herself the courting dance of the Panamanian manakin bird. It is mostly a hula-hula, though, when it slaps its wings on its thighs, there is just a dash of morris dancing. [continue]
