Anyone on this forum who takes their birds outside and on road-trips, shopping-trips, etc. with them, myself included, does it with their birds on a Harness and Leash, the most popular being the Aviator-Harness with lead...No one here, and no responsible parront will take their parrots outside at all without them either being on a Harness and leash or inside of a carrier or cage. Period. And yes, all birds can still fly away for miles and miles with their wings clipped, they can glide forever in the wind, so even if your bird's wings are clipped you still just cannot take them outside without either a Harness and leash on him, or while he's inside of a carrier or cage. Period.
The people who "Free-Fly" their parrots, meaning they take them outside to purposely fly them around off-leash, have been training their birds for years in order to do it. It's a very long process that involves a ton of Recall-Training of the bird first, before they ever go outside off-leash, and then it's a long training process of teaching them whistle commands, teaching them how to handled predator birds, teachiing them when and how to come back/land, etc. So it's not like they just take their birds outside and say "Go fly"...And even after years of training them and flying them outside, they still very often lose them do to a million reasons, from predator-birds chasing them off to them being starteled by something or someone or a sound, to them just simply flying away and not coming back. For this reason most people who have been training their birds to free-fly for years and years STILL purchased a GPS unit that attaches to the Aviator Harness, and they ALWAYS have the GPS unit on them when they are outside and off-leash, so they can track them on their phones, tablets, laptops, etc. if and when they take-off...
****Your Amazon most-likely isn't flying inside of your home because of a number or reasons, but "because he can't fly" isn't one of them. A lot of birds Amazon size and large don't often fly indoors because they don't feel like they have the space to do so, and they are actually afraid to spread their wings out the entire way. It's also possible that the prior-owner of your bird kept his wings clipped all the time, so he's used to having them clipped and not being able to fly INDOORS...And now you've had him for 6 months, his wings have grown back-in, and he's now starting to try using them again...If you take him outside I guarantee he will be able to fly, even if his wings aren't fully grown back in, and you'll end-up losing him, and we don't want to see that happen to you or anyone else, as it happens all the time because people mistakenly think that because they clip their bird's wings they can take them outside and they won't be able to fly...And then the first time they take them outside they lose them forever.
So, the bottom-line is PLEASE DO NOT EVER TAKE YOUR BIRD OUTSIDE UNLESS YOU HAVE HIM ON AN AVIATOR HARNESS AND LEASH, OR HE'S INSIDE OF A CARRIER OR CAGE AND YOU DON'T LET HIM OUT OF IT WHILE HE'S OUTSIDE...YOU WILL LOSE HIM!!! I've seen parrots with a very severe wing-clip, even into their Secondaries, take-off from their owner's shoulders and be gone, only to be found a week later 20 miles away...It's just not safe for Bill at all, and if you lose him you're going to feel horrible, and we don't want to see that happen...
***My suggestion to you is that if you want Bill to be a bird who goes places with you out of your house, but you don't want to keep him inside of a carrier or a Pak-O-Bird backpack, that you figure out the proper size of Aviator Harness for him and you order one online (Amazon or eBay are the cheapest places, and they both sell all sizes in all the colors available)...Witth the Aviator Harness you also get a leash that attaches to it, and most-importantly is a DVD with the training instructions...You cannot just put the Aviator Harness on most birds when you first get it and have them accept it, it's typically a process that takes a few months, but it's well worth the wait because it really is the ONLY safe way to take your bird outside without him being in a carrier or PAk-O-Bird. Some birds take to it more quickly than others, but typically you have to get them to accept having it put on them step-by-step, and then you also have to get them to accept wearing it without constantly picking at it and chewing on it once it's fully on them. So it will take time to get Bill to fully accept it so you'll be able to take him outside with you, but I'm warning you now as everyone else is, you DO NOT want to take Bill outside without being in a carrier of some kind or without an Aviator Harness on him, because YOU WILL LOSE HIM!!!
