Habitat infestation by weeds such as African boxthorn, Gazania, buffel grass and other invasive grasses.

Illegal bird smuggling and egg-collecting.

Change in the spatial and temporal distribution of resources due to global warming.

Loss of foraging habitat due to slashing/underscrubbing.

Degradation of foraging habitat and reduced regeneration of sheoak stands due to grazing by domestic stock.

Forestry activity resulting in loss of hollow-bearing trees, reduced recruitment of hollow-bearing trees, degradation of foraging habitat, and disturbance of breeding attempts.

Decline in extent and productivity of sheoak foraging habitat caused by moisture stress due to climate change.Disturbance from coal seam gas and open cut coal mining causing loss of foraging and breeding habitat as well as disturbing reproductive attempts.Limited information on the location of nesting aggregations and the distribution of high quality breeding habitat.Reduced access to surface water in close proximity to foraging and nesting habitat.Decline in extent and productivity of sheoak foraging habitat due to feral herbivores.Firewood collection resulting in loss of hollow-bearing trees, reduced recruitment of hollow-bearing trees, and disturbance of breeding attempts.Excessively frequent fire which eliminates sheoaks from areas, prevents the development of mature sheoak stands, and destroys nest trees.Decline of hollow bearing trees over time due to land management activities.Reduction of suitable habitat through clearing for development.A single egg is laid between March and May. Dependent on large hollow-bearing eucalypts for nest sites.Feeds almost exclusively on the seeds of several species of she-oak ( Casuarina and Allocasuarina species), shredding the cones with the massive bill.In the Riverina, birds are associated with hills and rocky rises supporting Drooping Sheoak, but also recorded in open woodlands dominated by Belah ( Casuarina cristata).Belah is also utilised and may be a critical food source for some populations. Inland populations feed on a wide range of sheoaks, including Drooping Sheoak, Allocasuaraina diminuta, and A.Black Sheoak ( Allocasuarina littoralis) and Forest Sheoak ( A. Inhabits open forest and woodlands of the coast and the Great Dividing Range where stands of sheoak occur.An isolated population exists on Kangaroo Island, South Australia. The species is uncommon although widespread throughout suitable forest and woodland habitats, from the central Queensland coast to East Gippsland in Victoria, and inland to the southern tablelands and central western plains of NSW, with a small population in the Riverina. For teachers, schools and community educators.See BirdLife's guide for Identifying South-Eastern Black-Cockatoos. Landcare Serpentine/Jarrahdale donated 38 cockatubes to the project, and these were transported from Western Australia to East Gippsland by the Australian Defence Force. This project is funded by the Australian Government’s Wildlife and Habitat Bushfire Recovery Program, and by donations to BirdLife Australia’s bushfire appeal.

We are also identifying sites with resources and a deficit of natural hollows, where we can install specially-made ‘cockatubes’ that the birds can use for breeding. We are working with the East Gippsland community and government agencies to protect unburnt stands of she oaks and plant new trees to replace some of those lost in the fires. This project aims to support the bushfire recovery of South-eastern Glossy Black-Cockatoos in East Gippsland by protecting their short-term food supply and increasing their long-term food security. The fires also damaged old trees with large hollows which Glossy Black-Cockatoos use for breeding. Glossy Black-Cockatoos feed almost exclusively on the cones of female she-oak trees, which can be 10 years old before they start producing cones. These fires burnt the fire-sensitive and patchily distributed she oak ( Allocasuarina) trees which these birds depend on for food. BirdLife Australia’s spatial analyses suggest that around 38% of the South-eastern Glossy Black Cockatoo’s ( Calyptorhynchus lathami) range was impacted by the 2019/20 bushfires.
