Hi, Merrick! I've heard of these folks before and I think what they do is a wonderful and awesome thing! Although Amigo free flys, I've never done "recall training" on him, he just comes when I call..he's an amazing bird. I have a lot of posts in the free flight section, even one called "Amigo's free flight "training"?" That is how we started our adventure with him
Although I've been tempted to fly our Goffins, Sassy, I hesitate because of her personality and size. I always told myself that I would never fly a bird smaller than a U2 because of predators but listening to the video you posted..if you have a healthy strong bird, she may be safe from the hawks!? My thought on that is, it depends on how hungry the hawk may be..or the hawks age, young ones are more prone to chase my Amigo than an older one,,this has happened.
Now, on the other hand..I have a friend up in Washington state that wanted to give me her pineapple conure. She travels a lot and wasn't sure she wanted the hassle of this little bird. She decided to keep her, little Nelly's her name and Nelly flys outside! My friend says she just cuts her loose, she flys like a bullet, super fast! Sometimes she's gone for up to two hours but always comes home. I'm not sure if Nelly comes when she's called but Im positive she's not "recall trained".
Working with your bird to free fly is very stressful, I think more so on the person than the bird but if it works..there are no words to describe the feeling
Oh! I wanted to add one thing! Sadly, the flight suit jumper, Graham Hunt, in that video just died, a few months back, jumping in Yosemite. He and Dean Potter, a pioneer to the sport, jumped at the same time and neither one lived . So sad. My son knew them both, they are from our area.
