Macaw Squinting or Keeping One Eye Closed: What It May Mean

A macaw may squint or keep one eye closed because the eye is painful or irritated. Common causes include dust, seed hulls, feather debris, mild conjunctivitis, and small scratches on the cornea. Birds with eye discomfort may blink more, rub the face on a perch, or resist handling around the head.

Trauma is another important cause. A macaw can injure an eye on cage bars, toys, rough perches, or during a fall or scuffle. Corneal ulcers and deeper injuries can look subtle at first, but they can become serious quickly. Swelling, cloudiness, bleeding, or a suddenly enlarged-looking eye are more urgent signs.

Infections can also affect the eye. Conjunctivitis in birds may be linked to bacteria, irritation, sinus disease, or a broader illness. In some parrots, eye discharge can happen along with sneezing, nasal discharge, lethargy, or appetite loss, which suggests the problem may not be limited to the eye.

Less common but important causes include uveitis, cataracts, glaucoma, vitamin A deficiency-related tissue changes, and disease behind the eye that makes the eye look painful or protrude. Your vet may need to examine both the eye and the rest of your macaw to sort out whether this is a local eye problem or part of a larger illness.

If your macaw briefly squints once or twice after bathing, preening, or getting a little dust in the face, you can watch closely for a short period. Mild irritation that resolves quickly, without redness, swelling, discharge, or behavior changes, may not be an emergency. Even then, the eye should return to normal fast.

Make a prompt appointment with your vet if the eye stays partly closed, the bird keeps rubbing at it, or you notice tearing, crusting, redness, or puffiness around the lids. Birds often hide pain, so a persistent one-eye problem deserves attention even if your macaw is still eating and vocalizing.

See your vet immediately if there was trauma, the eye looks cloudy, bloody, enlarged, or bulging, or your macaw seems weak, fluffed, off balance, or less interested in food. Eye problems paired with sneezing, nasal discharge, open-mouth breathing, or tail bobbing are more urgent because birds can have eye and respiratory signs at the same time.

A good rule for pet parents: if your macaw is awake and repeatedly keeping one eye closed for more than a few hours, it is safer to call your vet the same day. Waiting too long can make some eye injuries harder to treat and may increase the risk of vision loss.

Your vet will start with a full history and physical exam, not only an eye check. They may ask about recent trauma, new toys, cage cleaners, smoke or aerosol exposure, diet, bathing habits, and whether there are respiratory signs or changes in droppings, appetite, or energy. In birds, eye signs can be tied to sinus disease or whole-body illness.

During the eye exam, your vet may look for swelling, discharge, corneal cloudiness, pupil changes, and pain. They may use fluorescein stain to check for a corneal ulcer or scratch. Depending on the findings, your vet may also recommend cytology, culture, bloodwork, or imaging if they are concerned about infection, trauma behind the eye, or deeper disease.

Treatment depends on the cause. Options may include flushing debris from the eye, prescription ophthalmic medication, pain control, supportive care, and changes to the enclosure if an irritant or injury source is suspected. If the problem is linked to a respiratory or systemic infection, your vet may treat more than the eye.

Some macaws need recheck visits because bird eyes can change quickly. If your vet is concerned about a severe ulcer, penetrating injury, glaucoma, or disease inside the eye, they may recommend referral or more advanced care.

Home care should focus on safety and comfort while you arrange veterinary guidance. Keep your macaw in a calm, warm, low-stress space with clean perches and good air quality. Remove dusty bedding, strong cleaners, aerosols, smoke, and any toy or cage item that may have caused rubbing or trauma.

Do not use leftover pet medication or human eye drops unless your vet specifically instructs you to. Some eye products are not safe if the cornea is scratched, and birds can worsen an injury by rubbing after medication is applied incorrectly. If your vet advises a plain sterile saline rinse for suspected debris, use only exactly what they recommend.

Watch closely for appetite changes, reduced droppings, fluffed feathers, sneezing, nasal discharge, or lower activity. These clues matter because a macaw with an eye problem may also be dealing with a respiratory or systemic issue. If your bird is not eating well, seems sleepy while awake, or keeps the eye closed most of the time, update your vet promptly.

If your vet prescribes treatment, give every dose as directed and go to the recheck even if the eye looks better. Eye pain can improve before the tissue is fully healed. Early follow-up helps your vet confirm that the eye is actually recovering, not just looking less irritated.
