Apart from owls birds have never been regarded as the wisest creatures in the animal world. In fact we usually call stupid people - bird brains. Not anymore. In Bird Brains, world renowned conservationist Dr Carl Jones from Carmarthenshire, discovers that next to human beings, birds are probably the cleverest animals on the planet. They can add up, they can talk, they can identify concepts such as colour and shape and some even appear to have a sense of humour. Some scientists have even suggested that like us, they have self awareness.
