I hope I don't anger anyone, but I do have my avian vet clip my sun conure's feathers! He does get a period of time during the year where I let him be flighted, but overall he gets them clipped. They only clip the 3 main flight feathers, just so that he can't get lift and safely glide to the floor and we do it for his safety and our peace of mind. We adopted him when he was 4 years old, and he has always been clumsy, and startled by very random things, and that is with or without his flight feathers. He does fracture his blood feathers from time to time, but again this happens with or without his flight feathers. He is also the same cheerful, cuddly, sassy, hormonal, anxious, loud, and physically active boy, with or without his flight feathers. We get them trimmed because when he gets clumsy and scared, when clipped he very rarely hurts himself, but when he is flighted he almost always hurts himself. We have done flight training with him and we let him have time to be flighted throughout the year, but always without fail, he still will get startled and his first instinct is to slam into a wall or a window, no matter how much we have taught him. When he is clipped and startled he either glides to the floor and calmly waits for me to pick him up, or simply screams and I comfort him. It is because of this too we've had to get him a cage that is more wide than tall because he would fall off his perches in the tall cages provided to him. His happiness, health, and safety is our priority and we go through great lengths to ensure he is in a safe environment. Cygni has no shortage of stimulation, outdoor time, foraging, cuddles and love from us, even though we do get his wings clipped.
