Yeah, it's getting pretty late. 10:00 pm ?
What time is his usual bedtime? You should try to put him to bed every night around the same time. They like a routine. Do the same every night at about the same time.
For example every night around 8:30 or so I tell mine it's quittin time, almost time for bed.They go in their cage and I cover the back portion and give them just a little "night night treat". They KNOW what I mean now when i tell them that. They expect it. LOL Then at around 9ish I say lights out and turn off lights, turn on nite light.(Some keets are scared of the dark and get night frights) I still have tv on tho. Then at 9:30 I tell them time for bed and they go to their usual sleep spots and I cover them. All but the bottom part of the front. They freak out if I cover them completely.

I think the more you talk to them and explain what you are doing, they really do associate words with actions or objects.
