5 thoughts on “Long-billed Black-cockatoo (Zanda baudinii): Revise global status?”
I fully endorse the change of status from Endangered to Critically Endangered for the Baudin’s Cockatoo (Calypthorynchus baudinii).
Apart from the rapidly declining population trend, the Baudin’s cockatoo is a forest specialist that has not shown the same adaptation to the agricultural and peri-urban landscape as Carnaby’s cockatoos and Forest Red-tailed Black cockatoos. It is more dependant on the heavily forested areas of the Jarrah Forest Bioregion. Taking into account habitat clearing , wildfires and the slow recruitment rate of hollow bearing trees, this puts them at greater risk than the other two species. Artificial nest hollows have seen succes with Carnaby’s cockatoos but not with Baudin’s cockatoos.
In addition, they frequently travel in large flocks with Carnaby’s cockatoos and it is highly likely that because of this, their numbers have been overestimated in previous counts and are likely lower than stated above.
In short, there is no doubt that this species is the most threatened of the three black cocakatoo species in WA and the most vulnerable in regard to a rapidly changing climate and environment. It is therefore, in light of all information stated above, not overly cautious to change it’s status to CE but perhaps overdue.
Many thanks to everyone who has contributed to this discussion. We greatly appreciate the time and effort invested by so many people in commenting. The window for consultation is now closed and we are unable to accept any more comments until 21 February 2022. We will now analyse and interpret the new information, and we will post a preliminary decision on this species’s Red List status on this page on 21 February 2022, when discussions will re-open.
Based on available information, our preliminary proposal for the 2022.1 Red List would be to adopt the proposed classifications outlined in the initial forum discussion.
There is now a period for further comments until the final deadline on 27 February 2022, after which the recommended categorisations will be put forward to IUCN.
The final 2022.1 Red List categories will be published on the BirdLife and IUCN websites in July 2022, following further checking of information relevant to the assessments by both BirdLife and IUCN.

Recommended categorisation to be put forward to IUCN
The final categorisation for this species has not changed. Long-billed Black-cockatoo is recommended to be listed as Critically Endangered under Criteria A2bcde+3cde+4bcde.
