Welcome to my world. With my 3, when one of them behaves this way, they usually know it irritates me, and the more frustrated I get with their behaviour, the more they do it. Try a wanted item they don't usually get as a distraction, and pretend it is te coolest thing or the most forbidden item....they will want it and change direction.
I put small empty boxes on to of my counters or kitchen cabinets, that helped keep them busy enough so they behaved better. But you are right, patience......also,get used to it, it's life with a parrot!
