I will agree- the
Aviator Bird Harness is the best and most practical harness available, and it is designed almost especially for fully flighted birds, in that the leash part is made of 80% elastic/20% nylon, so that when your bird takes flight and reaches the end of the leash, it offers a slight resistance so that she can manuever back to you or to the ground.
All other harnesses on the market are made of 100% cotton or nylon, so when the bird reaches the end of teh leash, she is TUGGED back harshly and she hits the ground, unable to regain her balance after being tugged so hard.
Also, the Aviator harness automatically re-adjusts itself around your bird. Self-adjusting leash changes orientation as bird moves around handler. Automatically adjusts from the chest to the back as the bird climbs and flies.
They also sell the Aviator Flight line [

Like this:
You can also attach the end of the leash up to a retractable dog leash! I have the Aviator for my fully flighted Quaker, and I have a 16' long retractable small dog leash for hers. Just be sure that the retractable leash is appropriate for your bird's size..
The leashes made for bigger dogs are usually longer, up to 32', but they are also thicker and therefore heavier for small birds who can't fly with all that weight on them.
And that's another benefit of the Aviator versus the other harnesses- they are so light weight that even the small birds can use them! I tried all the other harnesses for my Quaker, she hated them all and they were so inhibiting & heavy on her. Once I got them on her, she'd slump over like a bag of mashed potatoes.
But the Aviator was so light and uninhibiting that she stands up correctly and even flies with her Aviator on!! The smallest Aviator harness weights only 5 oz. The Aviator's weight while on a small bird is the equivillant to your bird carrying an empty backpack. Other harnesses are equivillant to your bird wearing a 300 lb. backpack! =/
