The birds are now thought to be extending their range to recolonise areas occupied prior to European settlement. The removal of competition with rabbits through the introduction of myxomatosis in the 1950s, and the availability of extensive food sources, are believed to have led to a regrowth in Long-billed Corella numbers. These reliable, accessible food sources rapidly became staples of the Long-billed Corella’s diet.Ĭorellas are not popular on golf courses The removal of timber cover by primary industry combined with competition with rabbits and the uncontrolled use of poison led to a contraction in the range of the Long-billed Corella and a marked reduction in numbers. Pioneer settlement in Victoria replaced the original major food of the Long-billed Corella in particular the Murnong or Native Yam, with exotic grain crops and weeds including Onion Grass.

Prior to European occupation, Cockatoos occurred in large numbers in parts of the region. Long-billed Corellas, Sulphur-crested Cockatoos and Galahs, referred to collectively in the Report as 'Cockatoos', are members of the parrot family. What is known, and the number includes some individuals from the delisted birds (presumably prior to delisting), is that between 20 the Victorian Government issued authorities to kill 157,444 true parrots and cockatoos across eleven species, many still 'protected'.īelow is an extract from Problems in Victoria caused by Long-billed Corellas, Sulphur Crested Cockatoos and Galahs: Parliament of Victoria: Environment and Natural Resources committee 1995.

In Victoria these species will be killed in significant numbers, the extent of the killing is unsupervised and unknown.

In Western Australia the Western (Long billed) Corella was listed as endagered until 2011. In Victoria for example, three otherwise long lived parrot species, the Long-billed Corella Cacatua tenuirostris, Sulphur-crested Cockatoo Cacatua galerita and the Galah Eolophus roseicapilla are no longer protected.

This fact is denied by many of the country's politicians and the mass killing of birdlife continues.īecause Parrots live for such a long time, some species are persecuted and can be killed without requiring a permit to do so, the impact of a growing series of threats on populations, including the ones described here, are unlikely to be fully understood. On our wildlife property in Victoria, European wasps, a relatively recent invasive species, along with non-native bees were becoming a significant threat to tree nesting bird species, taking over their nests and killing the young.Ĭlimate change is also devastating birdlife and habitats across the continent. Given the high rates of deforestation and land clearing in Australia, nesting sites for many parrot species on the continent are going to be increasingly hard to find. We do not like birds in cages and we also do not like the mass killing of birdlife, the point is that there is a strange dichcotomy here. In the USA, cage bred Rose-breasted Cockatoos sell for around AUD 4250. In other countries the bird is prized by collectors and is, along with other Australian birds, quite valuable. The Rose-breasted Cockatoo is yet another example of a species of Australian wildlife that is disliked, a blame species on which much is blamed and and where most of it does not make sense. Eventually the poisoning stopped, and our poor old Galahs were then disposed of safely so as not to poison anything else. I think we made another forlorn effort to get something done, but nothing happened. Weeks passed and precisely nothing happened, apart of course from the freezer filling up with dead parrots. “Stick them in the freezer mate and we will come and look at them”

We thought we would ring the Victorian Department of Environment in the nearby regional city, Bendigo. The birds would sit on the grass, heads touching the ground, and then just fall on their sides to die. So our population of Galah's became smaller by the day, the dead birds were strewn around the lawn that surrounded our Victorian homestead. Loved by us, and clearly not be everyone, we discovered we had a ‘parrot poisoner’ in our midst. Some years ago now and at our wildlife property in Victoria, a long way from any farm or any kind of agriculture, set in a state park and surrounded by extensive forests, Australia's birdlife flourished on our lands, including numerous species of parrot.
