Perhaps take this time to reevaluate his diet (protein and fats especially), sleep and/or seasonal hormone cycle, handling, love-interests (animal, vegetable, mineral, human ;D) and write down any triggers for inappropriate adult behaviors or aggression that you can think of. And maybe start training hands off behaviors and direction such as stepping up on a stick, a ‘go home’ or ‘go to perch’ as future-proofing for petsitting and such, and just in case taking a break from his wings (and to some degree his full confidence and security) doesn’t fix the problem long term - the last thing you want is to feel trapped in a clipping cycle to keep yourself and your other birds safe! I’m glad you are all safe now! But please don’t think the problem has been solved by clipping... you just bought potentially more time than you need to change some major factors in his life. Working with him flighted in his cage for a few weeks might have been enough to start really developing the hands-off direction to keep you and birdies safe while other slower changes helped him feel different.
I have to reevaluate every couple of months, re-tailor things to my birds-of-the-moment, not the birds-they-were a season ago or before the mango ran out or we ate too many walnuts or before I got really busy and forgot to cuddle them exactly as much as is necessary. They let me know - Em-bird will gnaw much harder while I rub her ears if she has too much hormone-inducing rich foods, Mer-bird will be less interested in stepping up on fingers or even his trusty step-up wand if the cuddle-deficit gets too bad! Cheddar just had to let you know really really clearly this time
It can get better! Regular reevaluating is a normal part of any long term relationship, really.. we just have to conceptualise the process more clearly with our pets than with humans and take ‘bad’ or potentially painful behaviors as the loud communication they are.
