1/30/2024 0 Comments Blue cockatoo extinct![]() ![]() Thus scattered pairs of hooded robins may survive the initial clearing of woodland, hanging on in suboptimal scraps of disconnected habitat. ![]() Much of the damage has been done decades earlier and there is a lag between the triggering action and the loss of a species. Similarly, it is past and ongoing land clearing of habitat that has driven a suite of once common and widespread woodland species, the south-eastern hooded robin, southern whiteface, south-eastern brown treecreeper, diamond firetail and blue-winged parrot on to the threatened species list. All this has led to a 71% decline in reporting rates over the past 40 years. The increasing frequency and intensity of fires and the overgrazing of seedlings by rabbits, goats and kangaroos are speeding up the process and the placid pink cockatoo is losing out in the competition for the few remaining suitable hollows to galahs and feral bees. Their preferred nesting trees such as native cypress pines are on average 170 years old and even those that survived clearing and are protected in conservation reserves are beginning to die and fall to the ground. The main cause of decline is a lack of suitable tree hollows for them to nest in. Yet even such a stunning bird as this hasn’t avoided being placed in the endangered category. Even the normally sober field guides describe it as “flamboyant” and “beautiful”. While the eastern subspecies lives in out-of-the-way parts of the arid zone, it is a favourite due to its glorious colours. The red goshawk is now extinct in New South Wales and in Queensland is almost entirely absent south of Cape York Similarly, Coxen’s fig-parrot – uplisted to critically endangered – may have already slipped away unnoticed, with no verifiable sightings for decades in the dense Gondwana-era rainforests it once occupied. It could easily happen with almost nobody mourning its loss. This is why the Abrolhos painted button-quail is considered one of the five Australian birds most likely to become extinct.

Very few people would be aware of the painted button-quail that lives on the Houtman Abrolhos islands offshore from the Western Australian town of Geraldton. They say the first step to recovery is to recognise you have a problem, however, unlike the institution that made that phrase famous, anonymity is the last thing that threatened species need.Įxtinction is often a quiet process, happening out of sight. It is a line in the sand, a moment of hope that we have reached a turning point in the fortunes of a threatened species. ![]() There will be more birds added to the threatened species list as the federal environment department plays catch-up after years of delays, but a listing should not be seen as a tragic conclusion. ![]()
