Thanks for the answers!
So, let me see if I get this straight:
1. Squawking is normal, since he's new to the surroundings.
2. When he's flying around, he seems to be in "fly mode". That is, he still answers to my command - to sit on my hand, but he just sits for a short while, and he's looking for a new place to fly to. I just want to know if this is again ok - that is, I don't want him to get the idea that he's the boss around here
3. He's (in my opinion) very friendly and curious. He just came and sat on my laptop keyboard for a few times

He just comes, walks on the keyboard, even sat on top of the monitor, and stuff like that. When I take him in my hand, he again just stays for a while. He's in a playful mode

Again, is this ok?
4. If the answer to Q3 is ok, when should I to play with him - that is, hold him in my hand, pet him, make him sit on my shoulder? (that is, to make sure he won't keep on flying away)
5. He's been flying around for more than 2 hours. When is it gonna stop?
