Why is my parakeet panting, puffed up, and not talking? Is he sick?

Sorry to hear about Sky, but is sounds as if he is having respiratory problems (due to the tail bobbing). I would reach out to the Humane Society for help. It is important to seek help quickly as it sounds as if Sky is fairly sick. At home, providing heat support in the range of 85-90 degrees. This sometimes stimulates the immune system but will not replace seeking a veterinarian. Sorry I can't help more. Good luck.

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 Yes and including photos. Birds fluffed their feathers to provide more insulation, whether cold or ill. Providing heat support in the 80-85 F range can give some comfort. A veterinary visit is recommended to assess and help determine why he is acting ill. Monitor for food and water intake, might have to be separated from other bird to determine. Good luck.

Thanks for reaching out about Tweety. Providing heat support can give some aid but is not a treatment in itself. A veterinary visit is highly recommended, as Tweety appears to be ill. Check and correct diet, as an all seed diet is not sufficient for proper health. Vitamins, mineral and proteins are also needed. A vet visit should be scheduled for today, as we are entering the weekend and small birds do not have much energy reserves. Good luck

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.

Thanks for reaching out about Cactus. Could he be nauseous, trying to regurgitate? Fluffed up is a general sign of illness. Providing heat support in the 80-85 F range can give some aid. If weak, remove perches and place a soft towel on the bottom of the cage for comfort. Ensure that food and water bowls are within reach. Heavy metal toxicity (lead, zinc), metabolic disorders, ingested foreign bodies and infections are all possible. You need to see your veterinarian, to assess and provide a diagnostic/treatment plan. Good luck.

Thanks for reaching out about Sunshine and including photos. Providing heat support in the 80-85 F range can give some aid but a veterinary visit is highly recommended, as soon as possible, to assess and provide a diagnostic/treatment plan. Remove perches and place a soft towel on the bottom of the cage for comfort. Ensure that food and water are within reach. Veterinary care sooner than later, could improve prognosis. Good luck.
