Calyptorhynchus baudinii
Other names
Baudin’s Black Cockatoo and Long-billed Black Cockatoo.
Threatened Status
“Listed Endangered: Schedule 1 – Western Australian Wildlife Conservation Act”.
“Endangered: under Federal Environment Protection and Biodiversity Conservation Act“.
It is scarce to moderately common (most numerous in deep south-west). Mainly in flocks (up to 300 and occasionally larger aggregations of up to 1200 at roosts). It has declined in the last 50 years, its low rate of reproduction (0.6 chick per year) precluding it from replacing the large numbers shot by orchardists. In the last 10 years (since 2016), there has been a dramatic decline in numbers recorded at traditional roosts sites.
Breeding
