African Grey Parrot Eye Discharge: Causes of Watery, Sticky or Crusty Eyes

Eye discharge in African Grey parrots is a symptom, not a diagnosis. Clear tearing may happen with mild irritation, while sticky or crusty discharge can point to conjunctivitis, debris under the eyelid, trauma, or infection. In birds, eye inflammation may stay local to the eye, but it can also be tied to upper respiratory disease because the eye and sinus tissues are closely connected.

Common causes include bacterial infection, viral disease, fungal or parasitic disease, vitamin A deficiency, and irritation from smoke, aerosols, dusty bedding, or chemical fumes. PetMD notes that conjunctivitis in birds can cause thick white or tan discharge that crusts over, and Merck Veterinary Manual advises prompt veterinary care for redness, swelling, discharge, blinking, or holding the eye closed.

In parrots, discharge from the eye can also show up with sinus disease or systemic infections such as chlamydiosis (psittacosis), which may also cause nasal discharge, lethargy, appetite loss, or breathing changes. Trauma matters too. A scratch from a toy, cage bar, or another bird can lead to pain, secondary infection, and worsening inflammation if not treated.

African Greys are also prone to nutrition-related problems if the diet relies too heavily on seeds. Low vitamin A can affect the tissues lining the eyes, sinuses, and respiratory tract, making discharge and recurrent irritation more likely. Your vet will need to sort out whether this is a simple irritated eye or part of a bigger health issue.

See your vet immediately if your African Grey has a swollen eye, keeps the eye closed, seems painful, has a cloudy eye, has blood or pus-like discharge, or is also breathing with effort. Eye discharge with nasal discharge, tail bobbing, open-mouth breathing, weakness, or not eating is more urgent because birds often hide illness until they are quite sick.

A same-day or next-day visit is also wise if the discharge is thick, sticky, yellow, white, or crusting over, or if the problem has lasted more than 24 hours. Merck Veterinary Manual recommends prompt care for swelling, redness, discharge, excessive blinking, or holding the eye closed. PetMD also warns that untreated conjunctivitis can lead to more serious eye damage.

You may be able to monitor briefly at home only if the eye is mildly watery, your bird is bright and active, breathing normally, eating well, and there is no redness, swelling, squinting, or rubbing. Even then, if the tearing does not improve within a day, or if any new signs appear, contact your vet.

Because some parrot infections can spread to other birds and, in the case of chlamydiosis, may affect people, isolate a sick bird from other birds in the home until your vet advises otherwise. Wash hands well after handling your bird, dishes, or cage items.

Your vet will start with a careful history and physical exam. Expect questions about when the discharge started, whether one eye or both are affected, diet, recent new birds, cleaning products, smoke exposure, and any changes in breathing, droppings, or appetite. In bird eye cases, the cage setup and environment can matter, so details about substrate, perches, and aerosols are useful.

The eye exam may include checking the eyelids and conjunctiva, looking for debris or trauma, and using a fluorescein stain to look for a corneal scratch or ulcer. Depending on the findings, your vet may collect samples for cytology, culture, or PCR testing, especially if infection is suspected. VCA notes that bird workups may also include culture and sensitivity testing, and chlamydiosis testing may require a combination of tests because no single test is perfect.

If your African Grey seems sick beyond the eye itself, your vet may recommend bloodwork, imaging, or testing for infectious disease. A complete blood count can help look for inflammation or infection. In some birds, skull or sinus imaging is useful when swelling, chronic discharge, or suspected sinus involvement is present.

Treatment depends on the cause. Options may include flushing the eye, removing debris, topical ophthalmic medication, oral medication, supportive care, diet correction, and environmental changes. Your vet may also recommend temporary isolation and careful cleaning if a contagious cause is possible.

Home care should support, not replace, veterinary treatment. Keep your African Grey warm, quiet, and away from smoke, scented sprays, aerosol cleaners, candles, and kitchen fumes. ASPCA warns that birds are especially vulnerable to airborne toxins, including overheated PTFE-coated cookware fumes and secondhand smoke, both of which can irritate the eyes and respiratory tract.

If your vet approves, you can gently wipe away discharge from the feathers around the eye with sterile saline on gauze or a soft cotton pad, using a fresh pad for each wipe. Do not press on the eye, do not force crusts off, and do not use contact lens solution, redness-relief drops, or human antibiotic ointments unless your vet specifically recommends them.

Offer normal favorite foods plus vitamin A-rich bird-safe options your vet approves, such as dark leafy greens, carrots, red peppers, and formulated pellets if your bird is not already eating them. Good hydration and nutrition support healing, especially if the eye problem is linked to irritated respiratory tissues or poor diet.

Monitor appetite, droppings, activity, breathing, and whether one or both eyes are involved. If the eye becomes more swollen, cloudy, painful, or closed, or if your bird starts breathing harder or eating less, contact your vet right away.
