Bird Respiratory Infection: Signs, Causes, and Treatment

OT
Medically reviewed by Dr. Olivier Toulza
Reviewed 8 September 2026

A bird's breathing trouble is one of the fastest-moving emergencies in pet care. Their unique air-sac system means a respiratory infection can escalate quickly, so recognizing it early is critical.

Respiratory infections in birds show as tail-bobbing with each breath, open-mouth or labored breathing, clicking or wheezing sounds, nasal discharge, and reduced activity. Because birds have an extensive air-sac system, infections spread and worsen fast. This is urgent and needs an avian vet, who can diagnose the cause and prescribe an antibiotic like enrofloxacin or doxycycline when bacterial.

About enrofloxacin for birds: not currently available from PrepperPetSupply. See details.

How bird lungs make this urgent

Birds do not breathe like mammals; they have air sacs extending through much of the body, which makes their respiratory system efficient but also means infection can spread widely and fast. A respiratory infection that would be minor in a dog can be life-threatening in a bird within days. [1]

The signs to watch

Tail-bobbing as the tail pumps with each breath, open-mouth breathing, clicking, wheezing or sneezing, discharge from the nostrils or eyes, a change in voice, and tiring quickly. Any labored breathing is an emergency. [2]

Causes and treatment

Causes include bacterial infection, chlamydia (psittacosis, which can spread to people), fungal infection, and irritants like smoke or aerosols. Treatment depends on the cause; bacterial infections may need an antibiotic such as enrofloxacin or doxycycline. A vet identifies the cause and prescribes; we never set doses. When it is bacterial and a vet prescribes it, we can supply the medication after review.

Frequently asked questions about bird respiratory infection

Is bird respiratory infection contagious to humans?

Some causes, like psittacosis (chlamydia), can spread to people. This is one reason a vet diagnosis matters rather than guessing.

What antibiotic treats a bird respiratory infection?

It depends on the cause; enrofloxacin and doxycycline are commonly used for bacterial cases, at a vet-set dose.

How urgent is labored breathing in a bird?

Very. Treat open-mouth or labored breathing as an emergency and contact an avian vet immediately.
