African Grey sneezing — when should I worry?

My canary 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?

Interesting take! I see your point but I've had a completely different experience. My Eclectus actually...

This happened to us last winter. I think the shorter days and dry heated air were the cause for my bird.

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

I respectfully disagree. I think it depends heavily on the individual bird. My Jade is the total opposite.
