Since the morning scream is normal in many birds, this is usually the scream that you should just bear with. As long as it doesn't last too long, please let your bird be a bird and exercise his vocal calls.
If it does last too long, varying the time the lights go on & off as well as distracting your bird might help with this type of screaming. By distracting, I would suggest giving the bird food immediately when the lights go on before he starts to scream. If you wait until after the screaming starts, you have just taught him that he will receive food when he screams.
The best response to screaming is to ignore it. This is much easier said than done when your bird has an ear piercing scream – but it is important that the screaming not be re-inforced either positively or negatively.
If the screaming gets attention, you have just let the bird know that screaming gets him attention – even if the attention is negative, it is still attention.
When your bird is being quiet, go over & talk to him and maybe play with him or give him a treat. A bird responds best to positive re-inforcement and if you reward him for being quiet, he may be quiet more often.
Negative re-inforcement should be avoided.
Ignoring the scream and giving food and attention when your bird is quiet are the best methods to use. The screaming will not stop overnight – after all the problem did not start overnight either.
