I’m excited to tell you that the screaming and behavior issues we have been having with our parrots in this household has decreased drastically since we began implementing many of the ideas you suggested. Our birds are so busy foraging for their food. You always say “In order to change a behavior, you must replace it with another.” I now finally understand, the foraging has replaced much of the screaming and the birds now anticipate eating in a way to obtain goals! Thank you!
