The lack of knowledge about parrots is stunning! In this article, they feature a macaw that "remarkably, does not need a tether and flies freely before returning on command". Nothing remarkable about it. At one year of age, the bird is a baby and is simply not venturing far from its human (parent role) as any baby would do. Wait until the bird is 6 years old and come back and tell me if he returns every time...
