Birds are much safer in the house with their wings clipped, because there's much less that they can get into. It is possible to tame a bird that doesn't have its wings clipped, but it's more difficult. If you can't handle your bird and he isn't tame, it's definitely a good idea to clip his wings.
Yes by using Positive Reinforcement Training.
I have a pair of male parakeets one since Christmas (his mates died recently of a liver condition) and another since june upon purchase Gnarly's wings were cut but he was always more stand off ish and it took me a long time to really gain his trust. his first mate I was able to request that his wings be left uncut. but I had him Tamed almost imminently so having free flight rally wasn't that much of a problem because he was more willing to step up on me. by watching my interaction with Ripp Gnarly got the idea that I wasn't going to hurt him and I was able to handle him although our bond wasn't very strong. at my old place I used to leave there cage open and let them come and go as they pleased as long I as was home and awake. they never once tried for the many door or windows and Gnarly's wings grew back by about April and I didn't feel it was fair to have one free flighted parakeet and one not so I let them be. and for the most part for the next few months we were fine. in June I had to pack up and move back home for a few surgeries that had been planned for the summer. at my mothers place they dcan' have the freedom they used too because we have two very active cats that love chase birds so they can only be out when the cats are up and my mom is not working in the kitchen and I'm able to keep an eye on them which equals about mins 2 or 3 times a week. Now I can't catch or handle Gnarly
