Hi my female budgie Minty keeps opening and closing her mouth repeatedly with no sound coming out. She has done this before and I think she is fine, but I'm not sure and want to be sure she is okay. She closes her eyes and is standing still while doing this. She grinds er beak a bit too, Is she sick or just showing signs of comfort and happiness?
Agree with OP. Sometimes they will also stretch their necks while they open their beaks. Some people call it adjusting their crops while others will say there is no such thing. Doesn't matter really - it's a bird version of swallowing because you feel you have something caught in your throat
We are not Vets, Avian or otherwise. If you have any serious doubts about your budgies' health an appointment with an Avian vet should always be your first point of call.
