Carnaby’s Black-Cockatoo
Zanda latirostris
Carnaby’s Black-Cockatoo is endemic in the south-west of Western Australia. It is a large, dull black cockatoo and one of Australia’s five black cockatoo species. The population of this cockatoo has declined because of habitat degradation. Trees with suitable breeding hollows are rapidly being cleared and are in short supply. Research has shown that they need remnants of native vegetation within 12 kilometres of their nesting sites to raise healthy young.
The Carnaby’s Black-Cockatoo is a large, dull-black cockatoo with a short erectile crest and a large bill. The bird is primarily grey-black, with narrow off-white fringes to the feathers, giving it a scaly appearance. This is relieved by a patch of cream-coloured feathers on the ear coverts, and the tail has large white panels, especially noticeable when the bird is flying. The bill is grey-black on males and off-white on females; males have a pink eye ring, and females have a grey one; and both sexes have greyish legs and feet, though the females’ are paler. The average size is 55cm.
The Carnaby’s Black-Cockatoo is noisy with a distinctive ‘wy-lah’ call, though there is much variation. Bird call recorded by: Niels Poul Dreyer
The main song & call.
Credits to the owner/recorder.
The Carnaby’s Black-Cockatoo inhabits native woodlands dominated by eucalypts such as wandoo and salmon gum, as well as nearby heathlands and banksia woodlands. They need large hollows in tall eucalypts for breeding. Between December and July they migrate from inland breeding grounds back to coastal areas in the Swan Coastal Plain. This species can sometimes be seen in urban areas.
Distribution map
Carnaby’s Black-Cockatoo is often rather conspicuous, sometimes congregating in large flocks. They are even considered pests by some farmers when they descend onto crops of almonds and similar foods. Cockatoos may move along a branch, biting off cones or seeds and green branches for no clear reason.
The Carnaby’s Black-Cockatoo eats mainly seeds from the nuts of Marri, Jarrah and Protaeceae plants such as Banksia. They are also known to eat seeds from pine cones and will sometimes feed on nectar, flowers and insect larvae. They mostly feed in trees though will occasionally forage on the ground. They cut off seeds and cones with their strong bills and then hold the food with one foot while they strip the seeds. They sometimes forage in pine trees, pome orchards and canola.
Carnaby’s Black-Cockatoos breed in monogamous pairs, and nest in hollows in old eucalypts, which must be at least 100 years old to have hollows large enough. Pairs return to the same nest site each year. They lay one or two white eggs, which are incubated by the female for 28 days. The nestling period is 70 days, and both parents feed the chicks, but only the female broods them. If there is enough food, some couples can rear both chicks, though more often than not only one chick is successfully reared. The breeding female rarely leaves the hollow and is fed by the breeding male, though she may leave to get water nearby. The breeding season is from late July to January.
