# Budgie Breathing Problems in the UK

**Tail bobbing at rest, clicking breaths or open-beak breathing in a budgie is a same-day avian vet emergency.** Common causes include air sac mites, bacterial or fungal infection, and fume exposure. Keep the bird warm and quiet while you arrange care — small birds deteriorate within hours.

## Why budgies hide breathing illness

Budgies are prey animals and instinctively mask weakness. By the time you can see a tail bob or hear a click, the problem has usually been developing for days or weeks. According to UK avian-vet guidance, visible breathing effort in a small bird is always significant — never a "wait and see" symptom.

## Warning signs and what they suggest

| Sign | What it may indicate |
|------|----------------------|
| Tail bobbing at rest | Increased breathing effort — infection, mites or airway obstruction |
| Clicking or squeaking each breath | Classic for air sac mites; also tracheal infection |
| Open-beak breathing | Severe distress — emergency |
| Hoarse or lost voice | Air sac mites or tracheal disease |
| Fluffed, quiet, sleeping more | General illness — often advanced |
| Nasal discharge or wet cere | Respiratory infection |
| Sitting on the cage floor | Critically unwell — emergency |

## Air sac mites — the hidden budgie killer

Air sac mites (*Sternostoma tracheacolum*) live in the trachea, air sacs and lungs and are invisible to the naked eye. According to UK avian guidance, they are a common and underdiagnosed cause of breathing symptoms in budgies:

- **Signs** — clicking or squeaky breathing, hoarse or lost voice, reduced exercise tolerance, coughing or throat-clearing
- **Spread** — bird to bird, often from parent to chick; new birds can arrive already infected
- **Diagnosis** — a vet listens to the chest and may shine a light through the trachea (transillumination)
- **Treatment** — antiparasitic drops prescribed by the vet, usually repeated; **all birds in the household are treated at the same time**, because infected birds may not wheeze for several weeks

Untreated, a heavy infestation can suffocate a budgie — but treated early, most birds recover well.

## Respiratory infections

Bacterial, viral and fungal infections congest the airways so the budgie cannot get enough air through its nostrils. Contributing factors include:

- **Vitamin A deficiency** from seed-only diets, which weakens the airway lining
- **Dusty seed hulls, soiled bedding and ammonia** from droppings
- **Draughts and damp**, or poor ventilation
- **Underlying illness** that weakens immunity

See also [Bird respiratory infection UK](/health/bird-respiratory-infection-uk) for the wider picture across pet bird species.

## Household fumes — a silent cause

- **Non-stick (PTFE/Teflon) pan fumes** can kill a budgie within minutes, even from another room — never house birds near the kitchen
- **Cigarette and vape smoke, aerosols, air fresheners, scented candles and paint fumes** all damage delicate airways
- Move the cage to clean air immediately if you suspect fume exposure, and call a vet

## What to do right now

1. **Phone an avian vet** and describe the breathing sounds — ask for a same-day slot
2. **Warmth** — move the cage somewhere around 24–26°C, away from draughts; a sick bird cannot spare energy staying warm
3. **Quiet and dim** — reduce stress and handling
4. **Isolate** from other birds, but treat the whole flock if air sac mites are confirmed
5. **No human medicines** — cough mixtures and antibiotics must only come from your vet

## What the vet will do

Diagnosis may involve listening to the chest, transillumination of the trachea, swabs, or X-rays. Treatment depends on the cause — antiparasitic medication for mites, antibiotics or antifungals for infection, plus supportive care such as nebulisation, fluids and oxygen for severe cases. Complete the full course even if your budgie looks better.

If you also keep other birds, or anyone in the household develops flu-like symptoms, read [Bird psittacosis UK](/health/bird-psittacosis-uk) and mention bird contact to your GP.

## Emergency — go now

Rush to an avian vet or out-of-hours service if your budgie is breathing with an open beak, has a blue-tinged beak or feet, is unresponsive on the cage floor, or is tail-bobbing hard at rest. These birds need oxygen and treatment within hours, not days.

## FAQs

### Why is my budgie's tail bobbing when it breathes?

A slight tail movement is normal after exercise or in heat. Rhythmic tail bobbing at rest means your budgie is working hard to breathe — contact an avian vet the same day.

### What causes a clicking sound when a budgie breathes?

Clicking, squeaking or wheezing often points to air sac mites or an infection in the trachea or airways. Only a vet can tell the difference, so book an appointment promptly.

### What are air sac mites in budgies?

Air sac mites (Sternostoma tracheacolum) are microscopic parasites living in the trachea and air sacs. They spread between birds, cause clicking breathing and voice changes, and are treated with antiparasitic medication — usually for the whole flock.

### Can I treat my budgie's breathing problem at home?

Keep the bird warm, quiet and away from fumes while you arrange a vet visit, but do not give human medicines or wait it out. Small birds can deteriorate within hours.

### Can humans catch breathing infections from budgies?

Most budgie respiratory infections do not affect people, but psittacosis can pass from birds to humans. Wash hands after handling a sick bird and mention bird contact to your GP if you develop flu-like symptoms.
