zebra finch sneezing — when should I worry?

My Pionus 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?

Did this start suddenly or was it gradual? When my lineolated parakeet did this it turned out to be jealousy of a new person, pet, or even object in the home.

I've had birds for 15 years and I've seen this many times. In my experience it usually comes down to a subtle environmental change you might not even notice.

I have a similar story. My green cheek conure used to do the exact same thing. I remember being SO frustrated until one day it just clicked. Patience is truly the key with birds.

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