Since yesterday, bubbles has been vibrating her wings and carrying one foot at the same time. Usually we keep them near a window in the mornings where there's sunlight. She vibrates her wings a lot when she's kept here. When I move her back to the place where we usually keep her, she doesn't do it as often. She's eating, drinking, chirping and playing as much as she always does. Will it help if I post a video of her?
Do you mean that she holds them slightly away from her body and then vibrates? In my experience they do that sometimes when they are excited or nervous. Some birds love being in front of a window but others find it terrifying because things on the other side of the window are always changing, the light, traffic, people other birds or animals etc.
Is she fluffy with a slight vibration, or is it only the wings that are moving? Are they away from her body? Without seeing the position, it can be anything from cold, to excited, to neurological. Is everything else with Bubbles okay?
She's not puffed up at all and only her wings vibrate away from her body. Besides that... She hasn't lost any weight, her droppings are normal and she still eats and does everything else like she usually does. She only started doing this yesterday and I think maybe it could be a neurological problem? I've noticed that my other budgie bullies her and because she's terrified, she falls onto the cage floor but quickly climbs back up. Could something have happened because of that?
