My budgie is puffed up, leaning, biting, and gurgling. Is he sick?

Thanks for reaching out about Lemon and including photos. First, try offering some heat support with the goal of the 80-85 F range. A change in routine can be stressful, so trying spending more time with them, for observation and company. If they continue to be lethargic, a veterinary visit is recommended to assess and provide a diagnostic/treatment plan. Good luck.

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 Sprout and including photos. Being fluffed is a general sign os possible illness, nothing specific. A veterinary visit is needed to assess and provide a diagnostic/treatment plan. Providing heat support in the 80-85 F range can give some aid but is not a treatment. Monitor food and water intake. Good luck.

Given his age, he should be physically examined by your veterinarian or an experienced avian veterinarian. His symptoms have multiple causes and may require diagnostics to determine the underlying cause. In the meantime, keep him warm and as stress free as possible until he sees the doctor.

Thanks for reaching out about Baby. These are general sings of being ill and a veterinary visit is recommended, as soon as possible. Providing supplemental heat in the 80-85 F range can give some aid but is not a treatment. Problems could be metabolic (liver, kidney), infections, dietary deficiencies and more. Review diet and husbandry practices, correct any deficiencies. Good luck.

Thanks for reaching out about Pluto. By the signs you listed, it appears that Pluto is sick. A veterinary visit should be schedules soon as once birds show signs of illness, they are fairly sick. Providing additional heat support will help but is not a treatment. Good luck.

Thanks for reaching out about Kiwi. A damage flight feather should not alter flight significantly, as they can fly when they molt. Lethargy and sleeping during the day (to conserve energy) are clinical signs of being sick, the question is why. Providing heat support in the 80-85 F range can give some support. Monitor fecal production by a total cage clean-out. Sick birds often act like they're eating but aren't. A veterinary visit is recommended to assess and provide a diagnostic/treatment plan. Multiple possibilities include ingestion of foreign material (metal, fabric, wood, etc.), metabolic concerns (liver, renal), infections (viral, bacterial) and others. Good luck.
