About Carnaby's black cockatoo
Carnaby's black cockatoo (Zanda latirostris), also known as the short-billed black cockatoo, is a large parrot species endemic to the southwest of Australia. Described in 1948, this striking bird measures between 53 and 58 cm in length and is characterized by its predominantly greyish-black plumage, which features a scalloped appearance due to white edging on the feathers. Notable features include a short crest on its head, prominent white cheek patches, and a distinctive white band across its tail. Adult males can be identified by their dark grey beaks and pink eye-rings, whereas adult females have bone-coloured beaks, grey eye-rings, and more pronounced white ear patches.
Habitat and Distribution
This species inhabits a broad area of southwest Australia, primarily within the Wheatbelt region, typically in locations receiving over 300 mm of annual rainfall. Its range extends from Cape Arid in the east to Kalbarri in the north, with breeding occurring in areas receiving between 350 and 700 mm of rainfall annually. Carnaby's black cockatoo favors Eucalyptus woodlands, particularly those dominated by wandoo or salmon gum, and can also be found in nearby pine plantations and sandplains rich in Hakea, Banksia, and Grevillea shrubs.
Diet and Feeding Habits
The diet of Carnaby's black cockatoo is largely based on seeds from plants in the Proteaceae family, such as Banksia, Hakea, and Grevillea, with a secondary reliance on seeds from the Myrtaceae family, including Eucalyptus. They are known to consume seeds and flowers from over fifty native plant species. When feeding, they typically perch in trees, cracking seed pods or cones and extracting the seeds. They also forage for fallen seeds and fruits on the ground and have been observed to consume seeds from non-native plants, including those found in pine plantations.
Behavior and Breeding
Carnaby's black cockatoos are social birds, forming flocks when not engaged in breeding. They fly with deep, slow wingbeats, often at considerable heights. Vocalizations are varied, with a common call being a wailing 'wy-lah'. They nest in hollows high up in mature Eucalyptus trees, usually around 5.7 meters above the ground. The breeding season extends from late winter to summer, during which the female lays a clutch of one to two white eggs. The female incubates the eggs for 28 to 29 days, and the young fledge ten to eleven weeks after hatching. Young birds often remain with their family group until at least the following breeding season.
Conservation Status
Carnaby's black cockatoo is recognized as an endangered species by both the federal and Western Australian governments, and is also listed as endangered by the International Union for Conservation of Nature (IUCN). Major threats include the clearance of their feeding and nesting habitats, destruction of nesting hollows, competition for nest sites, and poaching. Significant habitat loss has occurred since European settlement, primarily for agriculture, and further development on the Swan Coastal Plain poses an ongoing risk. Their low reproductive rate and long period of immaturity also make them vulnerable to environmental changes.
