First transmitted in 1963, David Attenborough ventures into the bush to discover the unique wild animals that inhabit the Northern Territory of Australia. The bush walk reveals a wealth of wildlife including bee eaters, radjah shelduck, rose crested cockatoos, termites, kangaroos, wallabies, possums, an Australian crane and several lizards including the goanna, the thorny devil and the frilled lizard. Attenborough also closely observes the extraordinary behaviour of a bowerbird, which collects a treasury of white objects to display to its mate during courtship.
