Birds are famous for hiding illness, and nowhere is that more dangerous than with respiratory infections. In the wild, a sick bird quickly attracts predators, so pet birds instinctively mask symptoms until the disease is advanced. By the time an owner notices something wrong, the infection may already be serious. That is why every bird owner should know the early signs of respiratory disease and act fast — breathing problems in birds can become fatal within hours.

Common Symptoms of Respiratory Infection in Birds
- Tail bobbing — the tail pumps up and down with each breath, a classic sign of increased breathing effort
- Open-mouth breathing while resting, which is never normal in small birds
- Wheezing, clicking, or rattling sounds when breathing
- Nasal or eye discharge, or wet, stained feathers around the nostrils (cere)
- Frequent sneezing, especially “wet” sneezes with fluid
- Fluffed-up feathers, lethargy, and sitting on the cage bottom
- Voice changes — hoarseness, quieter singing, or complete loss of voice
- Loss of appetite and weight loss
Causes range from bacterial infections (such as Mycoplasma or Chlamydia psittaci, which causes psittacosis) to fungal infections like aspergillosis, as well as viruses, vitamin A deficiency from seed-only diets, dusty bedding, poor ventilation, cigarette smoke, and fumes. Overheated non-stick (PTFE) cookware deserves special mention: its odourless fumes can kill a bird within minutes and are a leading cause of sudden respiratory death in pet birds.
When to See a Vet
Contact an avian veterinarian the same day for consistent tail bobbing, nasal discharge, voice changes, or any breathing change combined with reduced appetite. Go immediately — treat it as an emergency — if your bird shows open-mouth breathing at rest, audible gasping or clicking, blue or purple colouring around the beak or feet, collapse, or inability to perch. Because birds deteriorate so quickly, waiting a few days to “see if it improves” is the most common and costly mistake owners make. While arranging the visit, keep the bird warm, quiet, and minimally handled, improve ventilation without creating draughts, remove dusty bedding, and never give human cold remedies or leftover antibiotics.
Common Vet-Directed Treatments
Diagnosis usually starts with gentle observation, then a physical exam, and may include blood tests, swabs, radiographs (X-rays), or endoscopy to view the lungs and air sacs directly. Treatment depends entirely on the cause:
- Antibiotics (often doxycycline or enrofloxacin) for bacterial infections such as psittacosis — typically long courses that must be completed fully
- Antifungal medication such as itraconazole or amphotericin B for aspergillosis, often given for weeks to months
- Nebulisation therapy — delivering medication as a fine mist the bird breathes in
- Supportive care including warmth, oxygen therapy, fluids, and assisted feeding for weak birds
- Environmental changes — removing smoke, aerosols, and dusty bedding from the home
Home Care During Recovery
Keep the recovering bird in a warm, quiet, stress-free space with stable temperatures. Offer favourite soft foods and fresh water, and monitor droppings and weight daily — weight loss is one of the most reliable indicators of progress. Clean the cage, perches, and bowls regularly to reduce reinfection risk, and finish every prescribed medication even if the bird seems fully recovered. If psittacosis is diagnosed, follow your vet’s hygiene advice carefully, since that infection can pass to humans; wash your hands after handling the bird and tell your doctor if you develop fever or breathing problems.
Prevention
Prevention beats treatment for bird respiratory health. Feed a pellet-based diet with fresh vegetables rather than seeds alone to prevent vitamin A deficiency, clean the cage daily, use low-dust paper bedding instead of fine sawdust, and ban smoking, aerosol sprays, and scented candles from the bird’s room. Keep the cage away from kitchens where non-stick pans are used, maintain humidity around 40–60%, and quarantine new birds for 30 days before introducing them to your flock. An annual check-up with an avian-experienced vet catches problems long before symptoms appear.
