...Then the dreaded bedtime arrives and he is so reluctant to go back in his cage, he knows it's coming and becomes aggravated and he will bite and/or fly away when I try to get him to step up, or if I try to gently pick him up with my hand, things he's very good at when he's happy and relaxed during the day. I normally have to follow him round the living room and attempt to pick him up a few times before I'm able to put him back, I'm trying to work out a good approach to addressing this as I don't want him to become stressed before bed and amke him dread it even more, and sometimes he'll fly at me too which is something i don't want him to develop further.
It's not this bad every night, but perhaps his evening routine needs changing a bit to avoid this happening, or perhaps I'm not handling the 'flying away' situation properly? To be honest I'm not sure if following him round the room is the best reaction when he does this or if I should just leave him alone for a few minutes? I've kind of assumed that leaving him alone teaches him that being aggressive and flying away gets him what he wants (ie staying out longer).
In terms of a change in routine, I've noticed that some people on here give their birds food in their cage at bedtime which may help him to see going to bed as a positive thing rather than a negative? I cover him at night, so I'm guessing I'd need to put him away with his food first, then leave him half hour or so before covering him for the night...
It would be interesting to see if anyone else has had similar issues or any suggestions which may be of use!
It's probably also worth mentioning that he's a year old now and has started showing signs of 'friskiness' (whimpering noises, funny wing dancing movements, regurgitating) 
so sometimes I think maybe his aggravated moods can possibly be explained by this but I don't want to use it as an excuse not to address the issue! x
