I built a bird play area for my two parakeets designed to be flexible, fun for the birds, and easy to clean.
Pegboard backer The entire back of the play area is made from pegboard. This allows me to mount their toys anywhere and rearrange them as often as I like to keep things interesting for the birds.
Butcher paper roller I added a roller at the base that holds a roll of butcher paper. This makes it easy to pull out a fresh liner, keeping the area clean with minimal effort.
