Well, you see, the thing about photoperiodism and it's direct effect on the endocrine system has nothing to do with what the bird learns is its schedule for awake or asleep periods. It's about their body being exposed to light. Period. It doesn't even have anything to do with actual sleeping because they are not like mammals. We, mammals, have only photoreceptors in our eyes so, when we close them, that's it for our body in terms of light but birds have photoreceptors deep inside their brains, very powerful ones that perceive light that actually shines through their skull (the cranium bones) which are very thin precisely because of this. So, even if the bird is fast asleep, if there is light, its body will be registering daylight.
As to your doing 'something right'... well, I am sure that you are doing A LOT of things right but, when it comes to keeping parrots in captivity, I am afraid that none of us is doing everything right. I wish I believed that I am doing things right but I know too much about parrots and I am too honest with myself for it. Captivity is real hard on parrots! I do mean REAL HARD! We really don't do them any favors by making them our pets. Quite the contrary - we pretty much screw up their entire lives! I once read an article written by an avian vet who specialized in necropsies (he was a professor) and he mentioned that their internal organs always look as if they had been 'besieged' by stress their entire lives. This phrase stuck in my brain as I was completely horrified when I read it... Imagine that - we keep animals in captivity that suffer from chronic stress caused by us! And this is why I am so strict about their diet, the light quality and schedule they are under, their being fully flighted, their having companions of their own or similar species, their being allowed to go through the motions of breeding, their natural daily biorhythms, etc. And why I do constant research in order to improve their lives as much as I can with the few things that we know make their lives healthier and happier! Because the mere thought of me, an animal lover, causing an animal such suffering is unbearable!
If I were you, I would forego the three nights of interacting with them so I could keep them at a solar schedule because doing it the other 6 days out of 9 will not work.
