If you can't solve the problem call your vet. Fluffing up the feathers Fluffing up feathers is not necessarily a sign of ill health. A budgerigar may do this when he is temporarily feeling hot or cold, or to aid in drying himself after a bath. However if a bird remains fluffed up continually it indicates a more serious problem. Seek advice from your vet.
Budgerigars are very susceptible to mites which mainly affect their face and claws.
Scaly face mite results in a crust appearing around the beak, cere and sometimes the eyes. If your bird is affected by scaly face mite you should apply an insecticidal powder or lotion recommended by your vet. Breathing diffculties and panting Any type of breathing disorder is a serious problem. Panting occurs only in extreme situations. It can be brought on by heat exhaustion, heat stroke or respiratory disorders.
