Thanks, Dianne. Observing is one of my many "hobbies" when I'm out in public. I'm not a very social person outside of the internet, so I just kinda like to sit back and watch. When you do that, you notice that people can be really funny, sometimes.

I took them in my room again, though it wasn't really meant to be a study. I put their toys on the floor and let them play, since I've found it keeps them busy, and they won't be bothering me if I were to have an iPad in my hands. Since we're watching someone else's dog (who likes to chase birds), they haven't had much time out of the cage lately, and they've been protesting very loudly about it. So I took them to my room to keep them busy and quiet, while I did my own things.
Well, when I first went in there, I realized that I didn't have my ipad. So I stepped out of the room. I could hear Alex screaming from the other side of the house, even with the bedroom door closed. I got back in, and they were in the same spot I left them, and Alex shut up.
At one point, I started whistling a tune that was playing in a video I was watching. It was a theme song to a show I watch, and I was catching up on the latest episode. I hadn't noticed that I was whistling until I looked down at the birds, and saw that they abandoned their toys, and walked over to the bed. I ignored them to see if they'll go back to playing. After exploring the little section of the floor they had migrated to, they got bored, and flew to me... Well, kinda.
Alex flew to the bed, and Lucy just kept flying upwards, and ended up in the closet. I wanted to see if she'll fly back, but before she made up her mind, dinner was ready and I had to put them back in their cage.
I might try and conduct another experiment like the last one, and see if I can successfully take Alex away from the toys with Lucy continuing to play with them.
Aside from observation and behavior analyzing purposes, I'm doing this to encourage their instinct to explore, as well as encouraging independent play. Being curious is a great way to exercise the mind, and since Alex and Lucy are both still young, I'd like for them to stay curious and open minded about things. It might keep their confidence up. Alex does seem to have some emotional issues due to his past, and I feel that the mental exercise may help him grow out of it. Lucy's been a good help with that too since she seems to keep him occupied to some extant, and at the same time, Alex is helping Lucy get used to things she's not used to.
Though Lucy and Alex are already good with independent play (since they play with
everything), I'm hoping to use what I've learned from observation to help Dudley, since he doesn't know how to play with toys. Granted, he is a different species altogether (he's a pionus, whereas Lucy and Alex are cockatiel) but I'm hoping that I might get
something out of it, that I can use towards helping Dudley out.
