What caused my budgie's death? Lethargy, limpness, nasal fluid.

I'm sorry to hear that Blue passed away. Unfortunately, the symptoms you mentioned are very vague signs of illness and can be caused by a number of things including infections, illness, malnutrition, respiratory diseases, injury and more. Without a necropsy (animal autopsy) to determine the cause of death, it would be impossible to tell what happened. If you have any other birds, thoroughly cleaning the cage and moving any sick birds to an isolated hospital cage can help prevent the spread of illness to other birds in your home. If you are having trouble coping with Blue's passing, checking out resources such as The Rainbow Bridge may help give you some peace of mind during your time of loss.

I'm sorry to hear about Noel's sudden passing. Unfortunately, birds are very good at hiding illness until it is too late, so it is possible Noel was ill for a while prior and it just wasn't noticed. Aging-related issues, illness, nutritional problems, sudden strokes, organ failure, etc are all potential causes of sudden death in an older bird. If you're having trouble coping with Noel's passing, checking out some online resources such as the Rainbow Bridge where you can chat with other pet owners and even create an online memorial may give you some comfort in your time of loss.

Thanks for reaching out and am sorry about Felix. Neurologic problems can arise for metabolic disorders (kidneys, liver, pancreas, heart), infectious agents (bacterial, viral, fungal), toxicities: just to name a few. Without a necropsy, it would be impossible to give you a diagnosis. Maybe having the other budgie tested for some infectious diseases, might be appropriate. Good luck.

Sorry about your bird. First thoughts are a respiratory infection, causing the wings to held outwards, then respiratory collapse. Respiratory problems can be caused by inhaled toxins, infections (bacterial, viral, fungal), metabolic disorder (liver, renal), and others. A veterinarian might be able to provide a necropsy for more answers. Good luck.

I'm sorry that Luna has passed away. Unfortunately, birds are very good at hiding illnesses or injuries until they are very ill and it is nearly too late, and without an exam, it would be impossible to tell what caused her passing. Illness, injury, parasites, etc, could all be potential causes. If your other bird is also acting ill, it would be best to bring him into a vet ASAP so he can be examined and treated for anything. If you're having trouble coping with the loss of Luna, checking out places such as The Rainbow Bridge can help you connect with other pet owners, create a pet memorial, and more in your time of need.

That is a lot of questions! And one I don't really have a good answer to. Sudden death can be caused by a number of things including illness, parasites, infections, nutritional issues, etc. It's always a good idea to first make sure the environment your birds are in is kept clean, and that they have access to a balanced diet and fresh water at all times. It is also a good idea to quarantine any new birds for a few days before introducing them to the other birds you own in order to prevent the spread of any illness. Stress from being put with strange birds, recently re-homed, switched to a new cage, etc can also cause a bird to act ill. Making sure they are in an environment that is free from harassment by other pets or people, is in a warm-draft free area, and that all birds can easily access food, water, perches and sleeping space is best. If you suspect one or more birds are ill it is best to separate them immediately into a hospital cage that is kept warm and with easy access to food and water to prevent the spread of illness and to keep any sick birds from being picked on. Seeking veterinary care to check for the cause of their illness is also a good idea.

I'm sorry to hear Bluey passed away. It is possible something underlying may have caused it, such as a stroke or seizure, and there was nothing you could have done differently to prevent it. Underlying illnesses, disease and more may have also caused him to become injured or ill and pass away. It sounds as if Bluey was in very loving hands until the end, and was very well cared for by you.
