New bird's stomach feathers shiver when breathing. Stress or illness?

Thanks for reaching out about Flint. Typically stress can cause rapid breathing but does not result in tail bobbing. Tail bobbing is due to difficulty breathing as in a large abdominal organ (liver, spleen), abdominal fluid or other problem. If continues, a veterinary visit is recommended. Good luck.

The tail bobbing, opening and closing mouth may be indications of respiratory difficulties. This may bebdut ot infection (bacterial, fungal or parasites) or trauma. The fluffed feathers, when taken with other symptoms may further point to potential illness. Ideally, she should be physically examined by your veterinarian for diagnosis and treatment. Birds are quite adept at concealing illness or injury so by the time they start to show symptoms, they may be very sick.

Pronounced tail bobbing coupled with a bit of lethargy may indicate respiratory distress or illness. Ideally, Pepper should be physically examined by your veterinarian or an experienced avian vet to diagnose and treat infection or injury. By the time birds begin to show any symptoms, they can be quite ill. In the meantime, keep him warm and as stress free as possible until he sees the doctor. Monitor for additional symptoms such as loose droppings or loss of appetite.

Thanks for reaching out about Sky and including photos. Birds are typically fluffed when cold or ill. A veterinary visit is recommended, sooner than later. Providing heat support can give some aid but is not a cure for illness. As a new bird, moving to a new home can be stressful for a young animal, and suppressing the immune system, allowing subclinical infections to manifest. Good luck.

An exam with your vet or an experienced avian vet is always recommended for new birds. At the very least, Phoebe will get a clean bill of health. The sleeping posture and squeaking noises are normal unless Phoebe is sleeping all the time. This doesn't seem to be the case by your description. Monitor for lethargy, loss of appetite or loose droppings. These are symptoms that should be addressed by a vet.

Shivering and beak opening can sometimes indicate stress in birds. Moving Mario to a quieter location, or in an area away from other pets and people and seeing if he feels better may help determine if this is the case. If he seems in severe distress, however, or his symptoms don't improve or worsen, a vet visit is best to rule out any health issues such as a respiratory problem causing his stress.

Shivering is unfortunately a general sign and not an indication of anything specific. It could be that your bird is cold or nervous, and moving her to a warmer, quieter location may help reduce stress and help her regulate her temperature. If she has other symptoms in addition to shivering, such as not wanting to eat or drink, changes in stool, sleeping all the time, etc, then this can indicate illness and should be checked out by a vet in person if she doesn't improve after a day or so.
