Red-tailed Black Cockatoo – Species Information
Calyptorhynchus banksii
This species has a 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).
Size differences among the five subspecies separate them into two major groups; with differences in female plumage making distinctions within each group.
