Note the brownish tinge to plumage (see General Description below). Carnaby's tend to much more destructive and will chew the rim off marri nuts to access the seeds.Ī male Baudin's Black-Cockatoo carefully hooks the seeds out of a marri nut. marri gumnuts), leaving little damage on the nut. Baudin's use their very long mandible tips to carefully extract seeds from woody fruits (e.g. This is the obvious and defining difference between the two species, and reflects a difference in feeding habits. We hope the following information is more useful! They are typically described in field guides as 'identical except for bill length', which can be unhelpful for birders who can't get a decent look at the upper mandible. baudinii) Black Cockatoos were only officially split by the first Christidis & Boles checklist in 1994.

The below article is from Leeuwin Birding Blog however it is without photos.
A number of black cockatoo chicks, honeyeaters and owls have been found dead in these hollows, often stung or engulfed by swarming feral bees. small parrots, Sacred Kingfisher and mammals e.g.
This has meant a reduction in the number of suitable hollows left for the obligate hollow-nesting species including cockatoos and other birds e.g. Whilst conducting field work on the black cockatoos, the WA Museum has come across large numbers of feral bee hives that have taken over tree hollows. Honey bees (managed hives) are now kept commercially for food and honey production, but feral bees have also become an increasing threat to our native hollow-dwelling fauna, particularly black cockatoos, through competition for suitable hollows, and possibly also competition for nectar. Honey bees were used to pollinate plants grown by early settlers for food - a task that was previously done by hand. The European honey bee (Apis mellifera) is an exotic species that was introduced into the Australian environment over 180 years ago.
