welcome to you and Babbage! It doesn't matter how many years you have parrots there is always more to learn, ideas for enrich their lives.
I learned from members here the importance of weighing your bird. When my burds got sick at the end of the year, this was invaluable! Do get a kitchen gram scale and weigh your burd weekly and log it. It's an easy thing to do and could one day save their life.
