Maui has been exhibiting this odd/distressed looking behavior since I first got her. It is very infrequent though, only about once per month or less. Anyway, I was finally able to capture it on video (this is really difficult because it is so short lived and so infrequent). The vet said she is fine (old, but otherwise okay). Her blood levels didn't show any surprising levels.
If anyone has any idea about the video, let me know.
An update on the birds:
Manzi and Maui are doing well. They are both enjoying a lot of me time, but my life has been busy. We have a move coming up in the next 1.5 months. The birds will get a much larger space. Our house will be over double in size. Their large cage will go in the main living area and we will finally build them the aviary that I've always wanted to build them. The new place has a concrete slab in the back where a shed is kept. I am thinking of removing that shed and building the aviary on top of that. It will make cleaning easy since I'd be able to just hose it off. Still, the house also needs a lot of work as well, so it may be several months before we get to the aviary.
It took the birds quite some time to adapt to this place and neither of them ever got comfortable with the second level. I'm hoping that they will adapt just fine to the new place. It is all one floor, which I am really happy about, so they will have an easier time exploring. We are not putting in any carpet, which will give me some peace of mind about Maui's wanderings.
We have had quite a bit of visitors and Manzi is still pretty eager to entertain. Last week he was flying to a visitor's hand taking treats from him. Maui does not go to visitors, but she will allow women to scratch her head (Manzi doesn't often allow strangers this).
We are currently surrounded on all sides by dog owners. After a full year of not imitating the dogs, our neighbors brought home a puppy. It is pretty cute, and now both birds torment the poor puppy, copying his puppy barks multiple times throughout the day. When the puppy is in the patio adjacent to the birds, the birds will began barking, causing the puppy to bark like crazy. They all continue on for several minutes until the neighbors bring the puppy inside. It is amusing (for me at least).
