Indian Ringneck sneezing — when should I worry?

My cockatiel has been sneezing a few times a day for the past week. No discharge, still eating and playing normally. Could it be the dry winter air from heating? Or should I book a vet visit?

I got mine from a local bird shop in Pickering. Great selection and the staff actually knows about birds.

I actually disagree with this. In my experience with my Eclectus, the opposite was true. But I know every bird is different.

This is one of those topics where I think there genuinely is no right answer. Both sides have valid points.

What does their diet look like? Sometimes these things are diet-related.
