Keen to protect our environment, flora and fauna. We must protect and save our black cockatoos, Baudins, Carnabys and Forest red tail black cockatoos.

Below are a few websites to assist with ID between the two white tailed black cockatoos, Baudin's and Carnaby.

"Baudin's bills can be quite strikingly long and thin, hence the rule of thumb "if you only think it's long, it's probably a Carnaby's". However, an examination of multiple specimens in the WA Museum suggests there is variation in the length of the upper mandible tip in both species, and thus a small area of overlap. In fact, the more diagnostic feature of the bill is actually its width - hence Carnaby's gained the specific name latirostris for 'wide-nosed'. Seen from the front, Carnaby's have a broad, arched shape across the top of the bill, whereas Baudin's is more triangular and narrow. The best published illustration of the bills, from Johnstone & Storr [2], is reproduced in WA Bird Notes 89, p. 12 [6] - available online at http://www.birdsaustralia.com.au/the-organisation/wa-bird-notes.html.
