Birds are fascinating creatures with a wide range of behaviors, and one intriguing behavior that often catches our attention is when birds close one eye. In this article, we will explore the reasons behind this behavior and its significance.

Closing one eye serves specific purposes in a bird’s life. It helps protect their delicate eyes from harm, such as dust, debris, strong winds, or intense sunlight.

Interestingly, closing one eye can also indicate contentment or relaxation in birds. It allows them to rest and conserve energy while remaining alert to potential threats in their surroundings.

However, it’s important to note that closing one eye can also be a sign of an underlying health issue. Eye infections, injuries, inflammation, or foreign objects may cause discomfort, leading a bird to close one eye as a protective response. If a bird consistently closes one eye or displays abnormal behaviors, consulting a veterinarian is crucial.

Understanding why a bird closes one eye requires careful observation of its behavior, environment, and overall health. Factors such as species, age, sex, and environmental conditions can all play a role in determining the cause. By monitoring a bird’s behavior and seeking professional advice when necessary, bird owners can ensure the well-being of their feathered companions.

In the following sections, we will delve deeper into the various reasons a bird might close one eye, including illness, injury, stress, and environmental factors. We will also explore how to identify if a bird is closing an eye due to stress or illness and discuss treatment options for eye injuries or illnesses. Finally, we will provide valuable tips on prevention and emphasize the importance of recognizing potential causes and seeking appropriate treatments.

Now, let’s explore the diverse factors that might lead a bird to close one eye and gain a better understanding of this intriguing avian behavior.

Birds may close one eye due to the following illnesses:

  1. Eye infections: Conjunctivitis or keratitis can cause discomfort and prompt a bird to close one eye.
  2. Respiratory infections: Sinusitis or nasal congestion can create pressure or discomfort around the eyes, leading a bird to close one eye.
  3. Neurological issues: Some neurological conditions can affect a bird’s ability to control its eyelids properly, resulting in one eye remaining closed.


Bird injury image

Injuries can also cause a bird to close one eye:

  1. Eye trauma: Accidents, fights with other birds, or colliding with objects can lead to eye injuries, causing pain or damage and prompting a bird to close its eye.
  2. Foreign objects: Irritation, redness, or discomfort caused by foreign objects, such as dust or debris, can lead a bird to close one eye.


Stress can significantly impact a bird’s behavior, including closing one eye:

  1. Emotional distress: Changes in the environment, loss of a companion, or loud noises can induce stress. Closing one eye helps birds feel more secure and protected.
  2. Fear or threat: When perceiving a threat or feeling scared, birds may close one eye as a defensive mechanism, allowing them to focus on potential danger while maintaining visual awareness.

Environmental Factors

Certain environmental factors can contribute to a bird closing one eye:

  1. Bright light: Intense or direct light can prompt birds to close one eye to shield their eyes from excessive brightness.
  2. Air drafts: Strong air drafts can cause discomfort to a bird’s eyes, leading it to close one eye for protection.

Understanding these reasons can assist bird owners in identifying the potential cause behind their bird’s behavior of closing one eye. By recognizing the underlying factors, appropriate measures can be taken to address the issue and ensure the bird’s well-being.

How to Determine if a Bird’s Eye-Closing is Due to Stress or Illness

By carefully observing the bird’s behavior, you can gain valuable insights into the underlying cause of its eye-closing. Stress-related eye-closing is often accompanied by signs of anxiety, such as excessive vocalization, restlessness, aggression, and repetitive behaviors like pacing or wing-flapping. On the other hand, if the eye-closing is due to illness, the bird may display lethargy, decreased activity, reduced appetite, weight loss, and difficulty flying or balancing.

Look for Physical Signs

Additional supportive care measures can aid in the bird’s healing process:

  • Dietary Adjustments and Nutritional Supplements: The veterinarian may recommend specific dietary adjustments or supplements to promote healing and boost the bird’s immune system. A well-balanced diet with appropriate vitamins and minerals contributes to overall recovery, while adequate hydration is important for well-being.

  • Regular Follow-up Visits: Birds with eye injuries or illnesses may require multiple follow-up visits to monitor progress. These visits allow the veterinarian to assess the bird’s response to treatment and make necessary adjustments. Regular check-ups ensure the bird’s eye condition is improving and address any new concerns.

By following these treatment options and collaborating with a qualified avian veterinarian, you can provide the necessary care and support for a bird with an eye injury or illness.

Birds are highly sensitive creatures, so their surroundings play a vital role in their health and behavior. Take these steps to provide a safe and comfortable environment:

  • Spacious and clean cage: Offer your bird a cage with ample space for movement and exercise. Regularly clean it to maintain hygiene and prevent harmful substances from accumulating.

  • Varied perches: Include perches of different textures and diameters in the cage to promote foot health. Avoid sandpaper-covered perches, as they can cause abrasions.

  • Toys and enrichment: Birds thrive on mental stimulation, so provide a range of toys like puzzles, bells, and ropes. Rotate the toys regularly to prevent boredom.

  • Nesting materials: If your bird enjoys nesting, provide suitable materials like untreated straw or shredded paper to create a natural and comfortable environment.

  • Ideal location: Place the cage away from drafts, direct sunlight, and extreme temperatures. Avoid exposing your bird to smoke, fumes, or chemicals, as they can harm their respiratory system.

  • Remove toxic substances: Ensure there are no toxic plants or substances within your bird’s reach. Research and remove potential hazards from their environment, including certain cleaning products, aerosols, and houseplants.

Careful Health Monitoring

Regularly monitoring your bird’s health is essential for early detection of issues. Keep a close eye on their well-being with these steps:

  • Behavioral changes: Pay attention to changes in behavior, such as aggression, lethargy, excessive vocalization, or altered social interactions. These could indicate underlying health problems or stress.

  • Appetite and droppings: Monitor your bird’s food consumption and droppings. Sudden decreases in appetite or changes in droppings’ color, consistency, or frequency may be cause for concern.

  • Physical discomfort: Look for signs of physical discomfort, such as feather plucking, excessive scratching, sneezing, or eye or nasal discharge. These symptoms could indicate underlying health issues.

  • Consult an avian veterinarian: If you notice abnormalities or have concerns about your bird’s health, promptly consult an avian veterinarian. Regular check-ups are also recommended for overall well-being.

Minimize Environmental Changes

Birds thrive on routine and can become stressed by sudden environmental changes. Minimize stress and promote a sense of security with these tips:

  • Consistent routine: Establish a daily routine for your bird regarding feeding, playtime, and sleep. Predictability helps them feel secure.

  • Gradual changes: If you need to make changes to the bird’s environment, introduce them gradually. For example, rearrange the cage or introduce new toys over time, allowing your bird to adjust comfortably.

  • Social interactions: Birds are social animals, so if there will be changes in their social interactions, such as adding or removing a pet or family member, ensure the process is gradual and monitored to minimize stress.

By implementing these preventive measures, you’ll create an engaging environment that promotes your bird’s well-being, reduces the risk of eye-related issues, and enhances their overall quality of life.
