Unfortunately with my bird, flying where she pleases, she also poos where she pleases. (lol I just realized I said poo) With cockatiel its pretty easy to clean up. Wet or dry just a wet paper towel. For bad spots (spots they sit in normally there for poops there a lot) I put an old hanker-chief there. Although I do go on poop patrol all the time wiping up the misc missed ones. TV's will be a big attractant. Their high and warm, ceiling fans are just trees with nice flat branches and curtain hangers are another big one.
Feel free to message me any questions, I'll try to help the best I can!
