Glossy Black Cockatoo – Species Information
Calyptorhynchus lathami
This species has a very large range, and despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations).
There are three poorly differentiated subspecies: Subspecies erebus is found in east-central Queensland. It may number c.5,000 birds, and range and abundance are probably increasing. Subspecies lathami has a patchy distribution in Queensland, Victoria, and King Island, Bass Strait. Its population of c.12,000 individuals is declining very slowly, and its range is contracting though its extent of occurrence is stable. Subspecies halmaturinus is now restricted to Kangaroo Island and numbers 70 breeding pairs. It is increasing due to conservation management.
