They scream in the morning and at night before bedtime and do the display when my moluccan gets over exited I try to distract him with toys. I play with him and after a while quite s him down. In the evening I turn off the side lights in my sitting room where his cage is. Bring out the black cage cover. By that time he gets the message climbs off his side perch and retires to the cage. Then I go to my bedroom.
