I struggled with this too. If you asked my husband, I have serious OCD issues with order and perfectionism (I just think of myself as a tidy person though

) and being in less than visually appealing or cluttered spaces really stirs up my anxiety a great deal. It's hard to incorporate parrots into your decor in such a way that is healthy for them but also looks nice to us. They are certainly not the most decor friendly critters despite their beauty

First off, his area is his, our areas are ours. I chose the shortest wall in the living room and the adjoining corner for his area. There is nothing in that area but parrot paraphernalia and besides a swing by the window (on the opposite side of the room) ALL his stuff is confined to his area and ALL his stuff has a specific place to be stored in his area to keep it as neat and tidy as possible. Toy storage, paper storage, nighttime cover storage, cleaning supplies EVERYTHING. No homeless parrot stuff bleeding into the rest of the living room making everything cluttered. When he's uncovered, cover goes in the bin, when I swap out a toy, it goes in the storage cart. He already makes a giant mess, I don't need to contribute further by leaving his stuff laying about. I hung a big custom printed shower curtain with a jungle scene behind his cage. I'l link below, but they aren't that expensive and look awesome! This both protects the wall with something easy to wash but also protects the thermostat and outlet on that wall. I have a big piece of board covered in easy to clean linoleum tiles under his cage/playstand to protect the cream color carpet and as a bonus, it further "defines" his area. I painted a big piece of scrap board leftover from the floor protectors and hung it in line from where the floor protector ends the create a visual end to his space. I also put his featherbrite lamp in a decorative fixture which looks a lot nicer than the stock fixture.
Safety, functionality and catering to the fact a bird lives there were my top priorities designing his area. My bird loves tacky colorful toys and I wouldn't take his favored forms of entertainment from him because it isn't the height of interior design. What I did do was keep the parts of the area he doesn't use nor care about (walls, floor, light fixture etc..) to pull in design elements and the #1 thing I did was keep his area his. He's happy and we're happy

And where to get the shower curtains. They have thousands of designs. I got the XL size to cover pretty much the entire wall:
