One assessment cited by the committee suggests that the 2019-20 fires had led to a decline in populations of 15% to 30%. The committee’s listing assessment for that population recommends its status remain at endangered.īut the south-eastern populations, previously unlisted, have been recommended for a vulnerable listing, in part due to the pressure on foraging habitat. There were fears for the birds on Kangaroo Island in the aftermath of the fire disaster, and concerns its status might reach critically endangered. Glossy black-cockatoos are also fire sensitive and are dependent on casuarina seeds as their food source. The female lays up to three eggs and the male and female gang incubate the eggs. The breeding season begins from October through January. The southern long-nosed potoroo is another affected animal and has been recommended for a vulnerable listing. Cockatoos are monogamous birds who pair for life and both the adult male and female gang prepare the nest together when the breeding season arrives. The committee has moved to quickly assess wildlife that might qualify for a threatened listing or upgraded threat status after the fire disaster.Ī decision on whether eastern koala populations should be listed as endangered is expected later this year.
“Any species that’s fire sensitive is going to really struggle,” she said. Immature birds look like the hen except for some red scalloping of the head feathers in young males, which may be seen even in the nest. The Gang Gang is dimorphic with the female lacking the red coloured head of the male. Length about 35 cm (14), weight about 250 grams. She said gang-gangs needed time to recover after such a disaster, something that would be made difficult with more frequent severe bushfire seasons. Red-Crowned Cockatoo, Red-Headed Cockatoo. “That would have potentially taken out nesting hollows and destroyed a lot of their foraging resources,” she said. Sarah Legge, a scientist who sits on the committee, said the bushfires had affected 36% of the birds’ range and about half of that had been burnt by high-severity fire. The listing assessment says increased heatwaves and fire frequency as a result of the climate emergency were increasing pressure on the species across its range, with bushfires likely to reduce the amount of nesting habitat available to the birds.
