Corbin has settled in really well. He arrived on Friday, and we took him to the our avian vet on Monday. After reading tons of books on too behavior, this is how we stopped the screaming.

He started to scream about a day into his new environment (not the morning or evening screaming - just screaming. There were 6 of us in the living room with him, we did not acknowledge his behavior, just got up and walked out of the room. After he was quiet for a minute, we came in and praised him. This took the better part of an hour, repeating the same behavior. He now screams a bit in the morning and night. I also gave him lots of foot toys, foraging toys to keep him busy.
He was on a seed diet, and I hand fed him Zupreem, and he now eats it by the clawful. As far as veggies, I will eat some in front of him, offer Nala some then offer Corbin some. He at least attempts to taste it.

Oh - check out tylerman22 for bird toys. She is really great to work with.
