Sulphur-crested cockatoos have one primary method of detecting and avoiding predators. When feeding, a few 'sentinel' birds will perch in a tree looking out for predators. They unleash their deafening warning call when a potential predator is sighted. Their large size also protects them from predation by all but the largest birds of prey.
During the incubation period and 6 to 10 weeks thereafter, both parent birds are intentionally very quiet in order not to attract predators to their nest.
Sulphur-crested cockatoos are known to be preyed on by powerful owls (Ninox strenua). Goannas (Varanus) are also potential predators of birds on the ground, fledglings, and nestlings. Other potential predators include common avian nest predators such as pied currawongs (Strepera graculina), butcherbirds (Cracticus), and ravens.
