Economic Importance for Humans: Negative
Sulphur-crested cockatoos can be so numerous in crop growing areas that they are often shot or poisoned as pests. Government permit is required, though, as they are a protected species under the Australian Commonwealth Law. Aside from crops, they can also be harmful to wooden structures and ornamental trees as they chew and rip at timber on houses and tree limbs.
