Found white cockatiel near library

I found a white cockatiel with bright orange cheeks and a sunny yellow crest this afternoon around 2:45pm, perched on a light post outside the Butte-Silver Bow Public Library on West Park Street. It seems in good health and was pretty chatty when I approached. The bird wears a blue leg band with the code 'A3' and has a small notch in the tail feather that's easy to spot. I’ve kept it safe in a carrier for now, hoping to find its owner soon. If you recognize this bird or you’re the owner, please get in touch so we can arrange a meetup near the library; I’d really love to get it back home.
