there's a raven at Dudley Zoo that is a caged orphan. It first of all says hello to you, and then in a way you could dismiss as stupid, brandishes a twig in it's beak through the cage mesh, in a way a dog or cat does its latest trophy or playing. What it actually wants is you to do is take the twig and stroke it through the bars on it's body. If you have a place to keep it, it would make a brilliant pet. Quite sad really, along with the orangutang that will not let you make eye contact with it, made me think of the mysery of bored unattended caged animals, all of them. They just shot a giraffe in the name of conservation. Something that clever doesn't do well being caged.
