Cockatoos like a lot of noise and interaction with their humans. When that's not possible, the sounds from the television or radio provide an acceptable substitute to help entertain your bird. Much like humans, birds go through a phase in their youth where they get a little cranky and rebellious. During this time, your bird may go from being sweet and affectionate to pushing you away. This phase can be a little annoying, but your bird will eventually get over it. Start by enticing your bird out, as not all cockatoos will come out on their own. To entice the bird out, make sure the room is safe by closing doors and windows and looking for hazards. Place a toy or treat just outside the cage or on top of the cage, then open the door and walk away. The bird will likely dart out and grab whatever it is you're offering. Place perches or landing spots around the room, including one near the cage, and over time, your cockatoo will likely explore farther out.  When checking for room safety, look for exposed wires, bare bulbs, flames, toxic plants, small hard objects that are easily swallowed, standing water, and hot burners. Hide or cover things you don't want the bird getting into. In addition, make sure to cover holes, such as those behind appliances. Cockatoos love to explore these holes, as they think they are tree cavities. To encourage your bird to interact with you, sit down near the cage sometimes when it is open. Speak in a calm tone to your bird and offer it treats from your hands.  Don't make quick or sudden movements.  Talk about anything at all, or read to the bird, always using a soothing tone. Allow your bird time out of the cage each day to keep it from getting bored but make sure you are around, as your bird will want to interact with you.  These birds can also cause damage to the things in your home very quickly, so you will want to keep your eye on them. This should be a period where you're actively engaging your parrot. You can play fetch or just catch with a small, soft ball or toy, such as stuffed animal, for instance, or you can show your bird how to put a small ball into a cockatoo-sized basketball hoop. They love to roll things on the ground.  Exercising your parrot helps it get out some of its energy each day. You can even get a bird harness for your cockatoo and take it outside on walks. To make sure your bird stays healthy, commit to an annual exam. Your vet can catch any health problem that may be creeping up and provide an appropriate treatment before it gets out of hand. Make sure to take your cockatoo to a vet who specializes in birds.

Summary:
Leave the radio or television on when you are out of the room. Be ready for the teenager stage when your bird is 4-5 years old. Encourage time out of the cage. Exercise your bird for at least 30 minutes each day. Take your bird to the veterinarian for annual exams.
