Does the screaming happens only in the morning and in the evening?
Does your cockatoo spends a lot of time alone or unattended?
Does the sounds your cockatoo make have some kind of a rhythm?
Does your cockatoo show any sign of an illness besides screaming?
Like many other bird species, cockatoos naturally announce themselves with a screech first thing in the morning and again in the evening. This behavior is common to all cockatoos, whether wild, captured, or domestically bred. This type of screaming happens at the same time every day.
Cockatoos are social animals. When you leave your cockatoo alone, he'll get lonely, anxious, and upset. He'll begin screaming for you or any member of his family to come back. Even if you're in the same room or nearby in your house, your cockatoo knows screaming will get extra attention from you. If you're not spending a lot of time with him, consider this his way of telling you he wants and needs more time with you.
Cockatoos are highly intelligent birds, but they have only a few ways to express themself. Whenever your bird is feeling happy or excited, he will start singing/screaming. These screams are usually a little different, and they have a bit of a sing-song rhythm rather than straight-out screaming. Your cockatoo will likely also be bobbing up and down, flapping his wings, or moving in some way that shows how happy he is.
Illness, including nutritional problems from a poor diet may cause the bird to change the amount of vocalization or other behavior. Rule out a possible illness by having your bird examined by a veterinarian.
Cockatoos often scream at someone or something that they perceive as a threat. He may be screaming at a cat walking through the yard, a plastic bag blowing down the street, or kids running through the house. Alarm screams usually are easy to identify, because your bird sounds distressed and anxious. If he is constantly warning you of non-existent dangers, consider placing his cage away from windows and doors, but in an area where he can still interact with the family.

Hi! I’m Sreten Filipović. I graduated from the Faculty of Agriculture at the University of Belgrade, with a master's degree in Environmental Protection in Agricultural Systems. I’ve worked as a researcher at Finland's Natural Resources Institute (LUKE) on a project aimed at adapting south-western Finland to drought episodes. I founded a consulting agency in the field of environment and agriculture to help farmers who want to implement the principles of sustainability on their farms. I’m also a founding member of the nonprofit organization Ecogenesis from Belgrade whose main goal is non-formal education on the environment and ecology. In my spare time, I like to write blog posts about sustainability, the environment, animal farming, horticulture, and plant protection. I’ve also published several science-fiction short stories.
