Quick answer
Sulphur-crested Cockatoos feed on seeds, nuts, fruit, roots, and insects, adjusting with season, age, and what is abundant in Woodlands, farmland, and urban parks of Australia and New Guinea. That label is a preferred pattern, not every item an individual might sample.

Sulphur-crested Cockatoo diet overview
Sulphur-crested Cockatoos (Cacatua galerita) are best summarised as Omnivore — seeds, nuts, fruit, roots, and insects. Anatomy and habitat (Woodlands, farmland, and urban parks of Australia and New Guinea) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How sulphur-crested cockatoos find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Sulphur-crested Cockatoo role in the food web
As consumers in their food web, sulphur-crested cockatoos move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild sulphur-crested cockatoos. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Crest signals and flock life
The yellow crest rises when the bird is alarmed, excited, or displaying — a visible signal across open woodland. Cockatoos feed in noisy flocks, screeching as they move between roost trees and feeding grounds. Strong pair bonds last years or life.
Intelligence and problem solving
Cockatoos open bin lids, dismantle lawn ornaments, and solve multi-step puzzles in research settings. Wild birds learn to exploit human food sources, becoming familiar sights in Sydney and Canberra suburbs where they chew decking and window frames.
