Unbearably noisy outbursts should diminish if you establish a schedule for feeding, cleaning, playtime, and bedtime. However, like their counterparts in the wild, pet birds vocalize at daybreak and dusk. Take a moment to respond. At night, be sure your bird gets 10 to 12 hours of uninterrupted sleep. A tired bird may be grouchy and, yes, noisy.
Many birds scream because they're bored or anxious.
Offer toys and a room with a view to keep your bird occupied. Turn on the television or radio, or play speech-training tapes for your bird when you're away from home. Pet birds frequently raise their voice in proportion to household noise. Lower the volume, and your bird will, too. Classical music may have a calming effect on raucous birds.
