The confusion here is the meaning of the word
Fledge.
Fledge is the stage in a young bird's life when the feathers and wing muscles are sufficiently developed for accurate flight and distance. This stage cannot be successfully developed with a 4 MT or 5 MT old parrot especially heavy short tailed parrots like greys, amazons

"""""African Greys and all parrots need to be fledged properly. The meaning of the phrase "fledged properly" means to allow a properly weaning baby parrot to learn to become an agile flyer. There is no set time limit for a baby grey to learn to fly. They need to be able to become graceful in landings and take offs, to hover and turn on a moments notice, being able to land on your hand from 20 feet away.
Giving a baby grey the freedom to learn to fly will give him the self-assurance he/she will need throughout their lives. I cannot express enough the importance of this. I have two birds that went through a terrible phase, luckily one recovered without behavioral issues. """"""

""""""Allowing a baby bird to learn to fly enables him to develop coordination and control. He learns to land where he intends to land, learns how to flutter to the floor safely and learns how to control his body. After he is clipped, this knowledge and confidence stays with him. A bird who knows how to control his body is much less likely to be injured.
If a Grey is clipped before he learns to fly with competence and control, he may not become a confident out-going bird. He may be fearful and insecure because he has not discovered his body's natural grace. This grace is learned through flight proficiency.
A baby Grey should be allowed to fully fledge. If the birds and the babies are clipped on an individual basis - taking into account their confidence level, strength, determination and power - this learned control and flying skill has become ingrained in the birds. As a consequence, they are much less likely to land awkwardly when fluttering to the floor.
I let my babies fly until I can't stand it anymore, but I have a high tolerance for inconvenience."""""

""""""""""fourth disadvantage concerns only some species, in whom the removal of flight ability can arouse significant feelings of vulnerability. This is true for some Red-tailed (Congo) African Greys, especially the more passive personalities among this species. Some individuals are genetically predisposed to experience more anxiety and fear than are others, and for these birds, clipping can result in increased behavior problems related to anxiety.
Lastly, there is a profound disadvantage to baby parrots in never being allowed to fledge and develop good flight skills prior to being clipped. I raise African Greys on a small scale. Each baby is fledged and flies for at least 8 weeks before any clipping is done. I have also taken in several older African Greys, who had lost their homes for one reason or another. Thus, I have had ample opportunity to observe the personality differences between those birds I have reared, fledged and kept, and those individuals I rescued who never had the opportunity to fly. The difference is like night and day.
When a young bird fledges, he learns to think. He learns to act volitionally. He goes through a mental and physical process every time he takes a flight. He decides that he wants to move, where he wants to go, then must figure out how high and fast he must fly to get there, and when to stall and hover prior to landing. This is a complex series of thoughts and actions.
If a parrot does not learn to think and act volitionally as a fledgling, there is little chance that he will ever do so, even if his flight feathers are allowed to grow out. I have three rescued older African Greys here who, although fully flighted, will sit in one place all day if I do not move them. They never learned to act with volition. Even though they are physically able to fly, it does not occur to them to do so.
I do not think that every species has such a profound reaction to being clipped as a youngster, but we might imagine that there is not the full development of the personality that takes place if, as a young bird, the parrot learns that he can go places if he wants to, and learns the attendant flight skills that enable him to do so. Simply put, flight enables personality development and expression."""""'

"""""More often than I like to hear, baby African Greys are clipped immediately after their first or second flight. This allows no time for them to gain confidence in their flying skills. I feel fledging is vital to the long term mental well-being of an African Grey. I theorize that baby Greys allowed a fledging period of several weeks are much less likely to feather pick a few years down the road, than their counterparts clipped after a single fledged flight.
Another large problem lies in the actual wing clipping of African Greys. Many people, whether they are veterinarians, pet store personnel, or even inexperienced breeders, clip African Greys like they would any other parrot. Greys are large bodied birds, not slip and not particularly graceful. Aerodynamic is not a word used to describe African Greys. Too often the wings of African Greys are butchered, causing the Grey to drop to the floor like a lead weight. Obviously this is dangerous as many Greys have split their chests open when hitting the floor. This type of wing clip and the dramatic landing results also causes trauma to the birds. If this unfortunate situation is the case with your African Grey, please allow the wings to grow out. Make sure the Grey re-learns, if necessary, how to fly, and have the bird properly trimmed once flight skills and self confidence are restored.""""""""""""""

""""""'Knowledgeable, understanding breeders like Phoebe Linden of Santa Barbara Bird Farm and Jean Pattison, Florida's African Queen, emphasize the importance of letting parrots fledge normally. Technically when a bird fledges it learns to fly. From that moment on the bird is in a different social structure than when it was in a nest being fed by its parents. As an animal that can fly the young parrot leans where and what to eat, how to respond socially to others of its own species.
In the wild, fledging is more than just learning to fly. It is where a young parrot's social personality starts to develop. Young Grey parrots interact with one another playing games that teach them future skills. They follow their parents to foraging areas, where they learn to eat. They learn who their natural predators are by following and watching older Greys.
One problem encountered with domestically bred Greys that are allowed to fledge is that they may not be left flighted long enough to develop self-confidence. """""""""

Now, as far as you thinking that I'm simply trying to convert people to my way of thinking---I said to go to other boards that are similar to this board where loads of individual owners are and read their experiences. I never said that you should go to areas where articles can be gotten. You don't need to go to bird boards to get those articles. All a person has to do is type in the author.They're generalized articles which might or might not pertain to individual people and their birds
As far as all of these so called well known authors are at, there are two very well known authors ( Bobbi Brinker--Maggie Wright) that just happen to post things on a well know bird board called the Manhattan Bird Club and if you read some of their posts, you'll see that they're constantly disagreeing with one another. Each one thinks they're right. At the end of each of their posts, they make sure they put their link in where you can purchase their book.
PS--concerning well known authors--be careful of the ones that decide tio give a set of instructions on how to clip a bird's wings in their articles
So, sorry if you think I'm putting you down. Just remember that the links above were the ones
you posted. It's their words, not mine.
