Generally I only take them to places I know I can still pay some attention to them. If it's some place where I'll be really busy, the last thing I need is poop running down my neck and nibbles on my ear. But if I'm going some place for the heck of it I bring my bird(s). I walk around my neighborhood with them, video store, parks, hardware store. Mainly it's food places you want to avoid because they have health laws and no need to make them uncomfortable. I did stick my head into a bakery though with Truman on my shoulder and asked them to make the sale at the door so I wouldn't have to go in. I think the employees were more busy checking out the bird and laughing about it.
I've brought the parrots to
high school reunion events and I even
bring Kili to carnivals. Also
I've taken my parrots to airports and
flying in airplanes. Pilots get jealous I have a copilot with wings.
I use and combination of harness, carrier, and travel cage for transporting the parrots safely. I also bring them with me to different people's houses and even a college dorm. Each of these experiences has helped shape them into calm and people friendly parrots.
The fresh air, socialization, and desensitization to new things is really valuable. I avoid bringing them to places (mainly food related) where it is likely to cause trouble. But never once have I gotten trouble for bringing them the places that I have, mainly just curiosity or not noticing.
