3 types of Australian black cockatoos found in the southwest corner of Western Australia and in Perth, Australia

The following is from Kaarakin Black Cockatoo Conservation Centre Perth. If you click on the link at the bottom of the post you will get to read the entire web page with identification charts of chewing marks and audio bird calls.

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.”

How many black cockatoos are left in the wild?
Below are estimates of the numbers of black cockatoos left in the wild in our region:

Carnaby’s cockatoos: Estimated numbers of 40,000.
Baudin’s cockatoos: Estimated numbers of 12,000.
Forest Red Tail cockatoos: Estimated numbers of 15,000.
If you would like to know more about the threats that black cockatoos face, please visit our “Black Cockatoo Threats” page.

How to identify the three types of black cockatoos found nowhere else in the world?
There are many ways to identify the black cockatoos:

Visual identification (look for the black cockatoo feathers, the bill ant the ear patch)
Calling sound (What do black cockatoo sound like?)
How they chew marri nuts
