Derivation
Cal-˙pt-o-rhynch'-us - Gk, calyptos, hidden; Gk, rhynchos, beak: baudinii - Nicholas Baudin, leader of a French scientific expedition in Autralian waters in 1802 - 3
Habitat
Forests, woodlands, pine plantations, orchards.
Population
Estimated population is 1,000 - 2,499 (2010) and decreasing.
Status EN
Desctruction of habitat for agriculture is the main threat. Competition for nesting sites by Maned Duck (Chenonetta jubata) as they increase in numbers may also be a future threat.
For more information see BirdLife International Species Factsheet.
Food
Feeds mainly on the kernels of proteaceous plants such as Hakea, Grevillea, Dryandra and Banksia. Also on fallen marri nuts or pine cones.
Voice
Contact call in flight, and sometimes while perched, a high-pitched, drawn-out, wailing whistle, 'whee-la', lasting about half of a second, the last syllable rather prolonged. A single-syllabled harsh call in alarm. Fledged young wheeze and rasp harshly and continuously.

Nest
In a hollow of a tree, usually karri or jarrah, from about 20 - 30 meters above the ground. The entrance is about 180 - 200 mm in diameter, widening to at least 350 mm at the floor, with a depth of at least 150 mm. The female selects and prepares the hollow, lining the floor with wood chips cut from the sides.
Eggs (Guide)
2; white; oval; about 48 x 35 mm. Incubation: probably about 4 weeks; by female.
Young
Usually only one of the two young survives to fledging.
Subspecies
Forms superspecies with Yellow-tailed Black-cockatoo (Zanda funerea) and Short-billed Black-cockatoo (Zanda latirostris). Long considered conspecific with latter, but currently treated as separate species because ecology quite different, and bill significantly longer than that of Short-billed Black-cockatoo (Zanda latirostris). Difficulty in field identification, compounded by long history of conspecific treatment, have led to uncertainty regarding limits of range in area of overlap, and to publication of some inaccurate maps. Present species has also, on occasion, been lumped in Yellow-tailed Black-cockatoo (Zanda funerea). Confusion over bill size of bird used in original description led to proposal of subspecies tenuirostris, but this name has now been shown to be synonymous with baudinii.
