This video shows how I trained my bird for flight outdoors. Your experiences will vary. DON’T DO THIS WITHOUT UNDERSTANDING THE RISK!
http://www.featherme.com/index.php/free-flying-your-parrot-outside/ is my article which goes over the basics of free flight with parrots. I am not an expert on the subject though. I’ve only trained one bird.
For in depth advice, go to http://wingsatliberty.com/articlesflight.html and read the articles by Chris Biro. He’s been doing free flight for years and with many different kinds of birds.
