It’s breeding season for our endangered Carnaby’s Black Cockatoos. PHCC staff and the Winjan Bindjareb Boodja and Harvey Waroona Rangers have been busy monitoring the development of Carnaby nestlings.

Winjan Bindjareb Boodja Rangers, Harvey Waroona Rangers, and staff from PHCC and City of Mandurah, recently attended a workshop hosted by Birdlife WA to provide training and certification to check Cockatubes and breeding hollows for Carnaby’s Black Cockatoos. We are now certified and ready to inspect hollows across Bindjareb Country, just in time for Black Cockatoo breeding season.

Monitoring results of artificial and natural hollows across the Swan Coastal Plain reveal cute Carnaby flufflings slowly growing into healthy young chicks. Eggs have started to hatch, and nestlings are now between 1-6 weeks old. At 10-12 weeks old they leave the nest but until then, nestlings are entirely dependent on their mother for feeding. The mother will stay with the nestling until it leaves the hollow and, during this period, the father will return to the nest daily to provide food for the mother.

If breeding is successful, the females will generally return to the same breeding hollow used previously (unless the hollow is already occupied). For this reason, it’s critical to protect successful breeding sites. Although they can live between 25-50 years, much of the remaining population is getting old and beyond the breeding age, which means there are fewer younger birds to replace them. You can help to protect Carnaby’s Black Cockatoos by conserving and restoring Banksia and Tuart Woodlands across the Swan Coastal Plain, which is their favoured foraging habitat.

Can you correctly guess the age of these two cute Carnaby fluffballs, using Denis Saunder’s Carnaby’s nestling ageing key below? Watch for more cute nestling images on our facebook page, as we continue to monitor nestling development and hollow condition.
