How to bird-proof a room for sitting

I agreed to watch my friend's parrotlet for two weeks. I don't have birds — what do I need to do to make my place safe? I know zero about bird care and I'm terrified of doing something wrong.

If you're in Leslieville, check out the avian vet on Lawrence Ave. They're amazing with parrotlet specifically.

Hang in there! It gets better. My parrotlet went through this too.
