Thank you for the tips

@Wendy Cooper-Wolfe ! I will try the slow exit and conditioning. I whistle back to him when I am there if he does the nicer noises - not the scream!
He has been doing much better when I am in there with him, the screaming is minimised for sure. And I don’t know if it can be eliminated fully if I keep going (I’ll try!) but having it lessened and working strategies to mitigate it when I’m working are so helpful. Although, when I have a meeting at 3 and set up the foraging box and then it’s moved to 3:30 that does mess things up a bit!!
We have some new foraging/puzzle toys arriving today as well as some different chews, I think he needs to be taught about which toys can be chewed on to keep that beak busy.
I have actually been setting up some of his existing puzzle and forage toys with seeds and some millet for when I leave the room and encouraging him to use it before leaving, but the majority of the screaming is still happening right after I finish work and leave the room for the evening. I’ve also set the radio on so it’s not total silence but will need to test if that’s actually keeping him too stimulated?
The later bedtime has been much better the last two days (if I jinx it again I’m never mentioning bedtime again) with no wake up calls, thank god!!
@Roz hormone wise, I don’t think so. No regurgitation, he’s only intermittently interested in the foraging box (seriously, I’m trying to teach him that he has to keep digging for the goodies and not just skim what he can see off the top

) and doesn’t have a hidey hut or anything. No dark spots I guess except the cardboard box he likes to climb on/in and chew to pieces, which he goes in less anyway now that I’m setting up other spots for him to play and interact with.
I am also hoping that starting target training will keep him entertained and occupied and “tire” him enough as well as give him enough direct attention, but more evening strategies are welcomed.
