Why are my baby budgies constantly opening and closing their beaks?

If the area is very hot then your budgies could be very warm. Open mouthed breathing and holding the wings away from the body are both signs that a bird may be stressed from heat. If they are old enough to leave the box, you can try to mist them with some cool water from a spray bottle (spray above them, not directly at them) or place a fan in the room to help create a bit of a cross breeze until it cools down. Making sure the birds have plenty of access to water and a shaded area to rest in can also help them keep cooler.

Thanks for reaching out about Cheeya. Opening and closing the beak, stretching the tongue would suggest at least two things. First, having difficulty swallowing, as if something is obstructing the esophagus or crop, or she is nauseous and attempting to regurgitate. The second thing that comes to mind, is a respiratory obstruction, something caught int he trachea. Placing Cheeya in the bathroom with warm steam might help lubricate either and help. But if clinical signs get worse or don't improve, a visit to an avian veterinarian is recommended. Good luck.

Buddy may be yawning. Birds will do this close to bedtime or when relaxed. It is normal and no cause for concern. Regurgitation is also normal and is characterized by an up and down motion of the head as whole seed or food is brought up to share with a mate or owner. If the behavior persists, consider an exam with your veterinarian or an experienced avian veterinarian to diagnose illness or injury or to give a clean bill of health and peace of mind.

Birds can sometimes do this motion to adjust their crop after eating, however if it is happening often, Warrior seems to be having trouble breathing, or there are other signs of illness (lethargic, not eating as much, listless, etc), a vet visit is best to rule out health issues.

Yawning or stretching the beak when perching could just be Zara attempting to relax, or even acting a little stressed from the handling. However if he is actively panting, appears in distress, or is acting this way even when not being handled, it may indicate an issue such as pain, illness, respiratory problems, etc which should be examined by a local avian vet.

Without more info it is hard to say. Holding the wings away from the body can sometimes be a sign of stress or illness, or can be part of heat regulation if your budgie is kept in a very warm area. Making sure she is cool, in a shaded area, and has access to food and water may help if she is feeling stressed. If she does show signs of illness, doesn't improve with the changes, or just doesn't seem right, a veterinary exam in person is best.

Thanks for reaching out about Coco. If he has been doing this for 3 years (since a baby), it is probably normal for him. But would not consider it normal. Open mouth breathing is often an indication of a respiratory problem, whether infection, organ enlargement (liver, spleen), or other concern. If persists or worsens, a veterinary visit is recommended. Good luck.
