Airsacculitis in Cockatiels: Causes, Symptoms, and Veterinary Care
- See your vet immediately if your cockatiel has open-mouth breathing, tail bobbing, blue or gray gums, severe weakness, or is sitting fluffed and struggling to breathe.
- Airsacculitis means inflammation or infection of the air sacs, which are a key part of a bird's breathing system. In cockatiels, it is often linked to bacterial, fungal, or mixed respiratory disease rather than one single cause.
- Common clues include noisy breathing, reduced activity, appetite loss, weight loss, voice changes, and breathing effort that seems worse with handling or stress.
- Your vet may recommend an exam, weight check, imaging, and testing such as cytology, culture, or endoscopy to look for infection, fungal plaques, or another underlying problem.
- Typical 2026 U.S. cost range for diagnosis and treatment is about $250-$1,800+, depending on how sick your bird is, whether hospitalization is needed, and which tests are performed.
What Is Airsacculitis in Cockatiels?
Airsacculitis is inflammation of the air sacs, the thin-walled structures that help move air through a bird's respiratory system. Birds do not breathe like dogs or cats. Their lungs and air sacs work together, so disease in the air sacs can make breathing harder very quickly. In cockatiels, airsacculitis is usually part of a broader respiratory problem rather than a stand-alone diagnosis.
This condition may be caused by bacteria, fungi such as Aspergillus, parasites, viruses, or irritation from poor air quality. In some birds, low vitamin A intake, chronic stress, smoke exposure, dusty bedding, or another illness weakens normal respiratory defenses and makes infection more likely.
Because cockatiels are small prey animals, they often hide illness until they are quite sick. A bird with airsacculitis may look only mildly tired at first, then suddenly show open-mouth breathing or marked effort. That is why any breathing change in a cockatiel deserves prompt veterinary attention.
Symptoms of Airsacculitis in Cockatiels
- Open-mouth breathing
- Tail bobbing with each breath
- Noisy breathing, clicking, wheezing, or raspy sounds
- Fluffed posture, weakness, or sitting low on the perch
- Reduced appetite or weight loss
- Voice change or quieter vocalization
- Nasal discharge or sneezing
- Exercise intolerance or breathing worse after handling
Mild respiratory disease in a cockatiel can look vague at first. You may notice less singing, less interest in food, or a bird that seems quieter than usual. As breathing becomes harder, signs often progress to tail bobbing, open-mouth breathing, or obvious fatigue after short activity.
See your vet immediately if your cockatiel is breathing with an open beak, falling off the perch, turning bluish or gray around the face or feet, or seems too weak to resist handling. Birds can decline fast, and waiting overnight can be risky.
What Causes Airsacculitis in Cockatiels?
Airsacculitis in cockatiels has several possible causes. Bacterial infections are common in pet birds with respiratory disease, but fungal infection is also important, especially Aspergillus, which can affect the lungs and air sacs. Other possible contributors include Chlamydia psittaci, Mycoplasma, parasites such as air sac mites in some birds, and mixed infections where more than one problem is present at the same time.
Husbandry often plays a role. Smoke, aerosol sprays, scented candles, poor ventilation, dusty litter, moldy seed, and chronic stress can irritate the respiratory tract or weaken normal defenses. Seed-heavy diets may also contribute because low vitamin A intake can affect the lining of the respiratory tract and make infection more likely.
Sometimes the air sacs are not the original problem. A cockatiel may develop breathing trouble because of sinus disease, tracheal disease, organ enlargement, masses, egg-related problems, or another illness pressing on the respiratory system. That is one reason your vet may recommend imaging and targeted testing instead of treating based on symptoms alone.
How Is Airsacculitis in Cockatiels Diagnosed?
Diagnosis starts with a careful history and physical exam, but birds with breathing trouble are handled gently because stress can make respiratory distress worse. Your vet will usually assess breathing effort, body condition, weight trend, hydration, and whether the problem seems to involve the upper airway, lungs, or air sacs.
Depending on how stable your cockatiel is, your vet may recommend radiographs, bloodwork, choanal or tracheal samples, cytology, culture, fungal testing, or PCR testing for infectious diseases. In more complex cases, endoscopy or laparoscopy may be used to directly view the air sacs and collect samples. This can help identify fungal plaques, inflammation, or material that does not show clearly on routine imaging.
The goal is not only to confirm airsacculitis, but also to find the underlying cause and severity. That matters because treatment choices differ for bacterial disease, fungal disease, parasitic disease, and noninfectious irritation. A bird that looks stable at home may still need oxygen, warming, fluids, or assisted feeding once examined.

Questions to Ask Your Vet About Airsacculitis in Cockatiels
Bring these questions to your vet appointment to get the most out of your visit.
- Based on my cockatiel's exam, do you think this is more likely bacterial, fungal, parasitic, or another type of respiratory problem?
- Does my bird need oxygen, hospitalization, or can care safely start at home?
- Which tests are most useful first, and which ones can wait if I need to manage the cost range?
- Are there husbandry factors in my home, such as smoke, dust, mold, or diet, that may be contributing?
- What signs mean the treatment plan is working, and what signs mean I should call right away?
- How should I give medications with the least stress to my cockatiel?
- Should my other birds be separated or monitored for contagious disease?
- When do you want to recheck weight, breathing, or repeat imaging?
How to Prevent Airsacculitis in Cockatiels
Prevention starts with air quality and daily husbandry. Keep your cockatiel away from cigarette smoke, vaping, aerosol sprays, strong cleaners, scented candles, and overheated nonstick cookware fumes. Use good ventilation, clean the cage regularly, and avoid moldy or dusty food and bedding. If a room feels stuffy or dusty to you, it is often much harder on a bird's respiratory tract.
Diet matters too. Many pet birds eating mostly seed do not get ideal nutrition, and low vitamin A intake can weaken the lining of the respiratory tract. Ask your vet whether your cockatiel's diet should shift toward a more balanced plan with formulated pellets and bird-safe vegetables.
Quarantine new birds, schedule routine wellness visits, and weigh your cockatiel regularly on a gram scale if your vet recommends it. Small changes in weight, appetite, or breathing can be the first clue that something is wrong. Early care gives you more treatment options and may reduce the need for hospitalization.
