I love the story of a person who kept their bird clipped, until they lost their bird outside. Yes, the bird was still clipped! After that, they decided to never clip again!
I find that rather amusing, since most people experience the opposite.
There are pros and cons to each side. Personally, I think birds should be flighted. If you didn't want an animal that could fly, you shouldn't have gotten a parrot!
I do understand why many people clip, but most of the time, the reasons are not valid.
Safety - a bird who can't fly far is less likely to fly into things or up high. Something to keep in mind, a clipped bird can't escape from a predator, inside or outside. A clipped parrot can't fly out of a trash can or a toilet. Flighted birds can. If a clipped bird happens to escape outside and gets lost, they are in more danger than a flighted parrot. That's a bit of a scary thought, when you think about it. A parrot that is used to flying is more likely to fly down from a high spot than a clipped parrot. Why? Because of experience! Birds can also be afraid of heights and "freeze up" once they get up high.
Behavior - bird becomes unmanageable when flighted. It's called training! Bird flies out of your reach? Teach the bird to fly back to you. Bird has an attitude? Go back to training the basics, minus the clipping part. Clipping a parrot doesn't solve the problem, it merely hides it. The problem is often a lack of proper training.
Potential dangers of clipping? Mmm.... lets see... broken legs, broken keel bone, broken beak...
Potential dangers of flight? Why say them, everyone knows them, but hardly anyone thinks about the dangers of clipping.
Weird...
