Glossy Black Cockatoo

Calyptorhynchus lathami

Also known as Glossy Black-Cockatoo, Casuarina Cockatoo

Glossy black cockatoos are dietary specialists that spend nearly their entire day methodically cracking open woody cones of sheoaks to extract individual seeds. Highly quiet and unobtrusive compared to other cockatoos, feeding pairs often go unnoticed until the continuous soft clicking of bills and falling debris betray their canopy perches. Monogamous pairs mate for life and rely on deep hollows in ancient eucalypts, producing just a single egg every two years.

Interaction riskLow

Low
Moderate
High
Very high

Why interaction risk is low: Safe to observe at a normal distance.
What to notice: Look for a dull black-brown plumage with bright red tail panels in males or yellow head patches in females.
Support conservation: Keep at least 30 meters away from feeding and nesting trees, keeping voices quiet to avoid causing them to flush.

Responsible observation

Listen for clicks: Locate feeding birds by the steady sound of cracking cones and falling debris.
Maintain distance: Avoid lingering near active tree hollows during the autumn and winter nesting season.
Scan sheoaks: Check mature stands of Allocasuarina, where quiet pairs often feed unnoticed for hours.
