Are black cockatoo endangered?
The glossy black-cockatoos are one of the more threatened species of cockatoo in Australia and are listed as a vulnerable in NSW.
Carnaby’s black-cockatoos are listed as endangered in WA.
Baudin’s black-cockatoos are listed as endangered in WA.
The Yellow-Tailed black-cockatoos are listed as vulnerable in SA, and secure in NSW, QLD, TAS, ACT and VIC.
Red-Tailed black-cockatoos:
b. graptogyne is listed as endangered.
naso (Forest Red-Tailed black-cockatoo) is listed as vulnerable (near-threatened)
According to the 2019 Great Cocky Count:

“Despite a recent stabilisation of the local population, the trend since 2010 shows a 35% decline of Carnaby’s and a 13% decline per year of Baudin’s. A precautionary approach dictates that efforts be made to protect remnant vegetation of Black-Cockatoos, particularly Banksia woodlands and Marri/Jarrah forest. Revegetation of former pine plantations should be a priority to ensure no feed gap in the future.”
