I just got my girl an Aviator harness and the instructional video that came with it is really informative. The guy explains and demonstrates how to get your bird used to and comfortable with the harness, and then how to get your bird used to letting you lift its wings, put the harness over its head, etc. I think you can find the company's videos on youtube - try searching for "parrot aviator harness." I worked a bit today on getting my bird comfortable with me lifting her wings a bit. I'd left the harness sitting around her cage for a while for her to get used to it, and she's pretty good with small foreign objects so it didn't freak her out when I started messing around with it on her (petting her with it, getting her used to it being around her back, etc). She was being really docile and good so I tried slipping it on, not to take her outside but just to practice putting it on and taking it off. Well, she was fine until I tried to fasten it, the last step. Suddenly she flipped out and started grabbing at the harness, flailing about trying to get it off of her. I did my best to remove it quickly and to remain firm with her, but she was pretty freaked out for a minute after that. I guess I got a little ahead of myself and tried to put it on her too soon. Tomorrow I'll go back to just working on lifting her wings and getting her comfortable with me touching her with the harness, but I won't try to put it on her again. When I do, I think I'll work on just getting her comfortable with one step at a time - one day getting her used to having the collar part around her neck, the next day putting it around her neck and wings, and then the next day putting it on and then fastening it onto her. The guy in the video explained that what you really don't want to do is try to slip the harness on quickly to get it over with, because that will just make the bird hate putting the harness on every time.
