My B&G Macaw raises her wings gives one gentle flap & she is airborne. She can turn on a dime & maneuver her way around the doorways, ceiling fan, etc. Even tho she is fully flighted she prefers to walk. Same with our CAG, she prefers to walk. In spring we wing clip just enough so they can't get too high in the air. We have an aviary at the end of our back yard, where they spend all day climbing, swinging, digging holes in the ground, etc. My macaw can go about 15 feet clipped, so I toss her & she lands in the yard & then walks the rest of the way to the house.
Wing flapping is good exercise. It helps to keep their wing muscles strong, which also helps with their balance. I hold them on my hand, feet held with my thumb & make them flap, swing them upside down & back up.
In the wild they'd all be flying a lot every day looking for food, so any exercise they get in captivity is better than none.
