It has great bill black, crest erectile, white spot in the area ear and white panels on the tail. The female It is similar except patch area ear large and slightly yellowish white.
The immature Similar to adult female.
Closely related Baudin’s Black Cockatoo (Zanda baudinii). They were formerly treated as a single species.
- The Slender-billed Black-Cockatoo sound.
Mainly inhabits in native forests eucalyptus and shrubland or heathland. Visit temporarily plantations exotic pines.
Sometimes you see them in cities or at the edges of roads. It is also a visible visitor to the gardens containing native plants with hard fruits around Perth.
Usually they see them in groups of three or in small flocks, but occasionally gather in large flocks composed of hundreds or, exceptionally, thousands of birds. Sometimes it is associated with Baudin’s Black Cockatoo (Zanda baudinii) wave Red-tailed Black-Cockatoo (Zanda Banksia) in places where food is plentiful.
The species is said to be Residents in areas of high rainfall They are retaining much native vegetation and are emigrants of the driest regions and places where most of the native vegetation has been removed.
They do not breed to at least four years of age.
Adult birds They mate for life, and stay together throughout the year.
Reproduction occurs mainly in the region Wheatbelt, northwest of the Stirling Range about Three Springs, but it has also recorded on the coastal plain in the South West, about Bunbury.
The reproductive activity It is limited to eucalyptus forests. They make their nests in large holes in the top of the eucalyptus.
The eggs They are white or cream, and they have no marks. Are incubated by female only, for a period of 28 to 29 days. The nestlings are fed by both parents, Although during the first 10 to 14 days after hatching are fed exclusively by the female.
Adults return to the same breeding ground each year.
It feeds mainly from seeds and occasionally nectar, fruit and insect larvae.
Tamaño del área de distribución (reproducción/residente): 196.000 km2
Endemic southwest Australia.
• Current red list category of the UICN: In danger of extinction.
• Population trend: Decreasing.
On the basis of the distribution of birds during the breeding season, the total population of the Slender-billed Black-Cockatoo it has been estimated that is between the 11 000 and 60 000 birds, Although there are those who claim that their population could have less of 10 000 birds.
The decline of this species It is mainly due to the loss and fragmentation of habitat. This has been caused by the clearing of native vegetation, mainly for agricultural purposes, Since the mid-20th century.
There is no specific information available about future changes in the size of the population. However, It is believed that the range of the species will continue to shrink for a while, which leads to a concomitant decrease in population size.
A program captive breeding It was established in 1996 by the Department of Conservation and Land Management (CALM), in association with poultry farmers and licensed Zoo of Perth.
Genetic diversity in the captive population is enhanced by a program ' abandoned’ It rehabilitates injured wild birds and then incorporates them into captive breeding.
Some eggs and chicks are caught illegally for sale in the markets of poultry. Although it is said that the demand for the species has decreased during the last decade, high market prices (approximately 3.000 dollars per bird and 5,000 $ couple) along with the lack of success of captive breeding, They suggest that the illegal capture of this cockatoo will remain a continuing threat to the survival of this species.
