Clipping wings is a highly controversial subject, the best answers are delivered respectfully and without rancor!!
I do not clip any parrot's wings, but take extreme care to prevent injury or escape. Given a bird's natural tendency to fly, it is IMHO our responsibility to fulfill as much natural activity in captivity as possible. With one exception, all my flyable parrots are skilled and don't tend to crash into walls or objects. All windows and doors must be secured, and when birds are loose it is imperative to prevent a surprise unintentional opening of a door from the outside! Ceiling fans are deadly and not all birds show a natural fear. All occupants of the house must be aware to prevent hazards such as hot stoves and open toilets. Other pets such as dogs and cats must be properly assessed and absolutely removed if they pose the slightest hazard. If your bird has frequent flight privileges, one might reduce their guard over time. Birds can and do explore the floor and present a tripping hazard - dangerous to you and deadly to them.
If you choose to clip, there are several options! A "light clip" permits the safe fluttering to the ground but prevents liftoff from a stationary position. The most controversial is asymmetrical; just one wing is clipped. While intended to discourage a bird from flight, it takes several potentially dangerous attempts and subsequent crashes to "train" out the behavior. I am *not* a fan because of the physical and psychological trauma.
