Ray has tried to persuade these authorities to allow export of these species, but to date these attempts have been rebuffed.
John Mollindinia noticed during his visit that there were few Major Mitchell’s cockatoos to be seen and then discovered that they suffered from constant predation by goannas, a species of monitor lizard, which nimbly climb the trees when, for instance, they hear chicks calling for food and gobble them up whole. The lizard concerned is the Lace monitor (Varanus varius), which is the second largest of this reptile group reaching 2 metres (6½ feet) in length and weighing as much as 20 kg (44 lbs). They can forage over long distances (up to 3 km - nearly two miles) in one
day and feed on insects, smaller lizards, snakes, small mammals, birds and eggs, which they usually eat whole. They also feed on carrion as well as food waste in domestic rubbish in inhabited areas. The name goanna is believed to be derived from “iguana” with the initial vowel sound dropped because the aborigines found it difficult to pronounce. In addition to the lizards feral cats also predated the nests of the cockatoos. Ray told John that he thought that the problem might be resolved by placing a smooth flexible sheet of tin at least one metre in height around the trees below the nesting cavities which would act as an effective barrier to either lizards or cats reaching the nest. Branches also needed to be cut back on surrounding
