Do Cockatiels Need Light at Night? An Expert Guide to Cockatiel Care.

Cockatiels are diurnal birds, which means they are most active during the day and sleep at night. In general, cockatiels require around 10 to 12 hours of sleep per night. However, the exact amount of sleep a cockatiel needs can vary depending on factors such as age, health, and environment.

Do Cockatiels Sleep with Their Eyes Open or Closed?

Cockatiels have a unique sleep pattern where they keep one eye open while the other is closed. This is known as unihemispheric slow-wave sleep. It allows them to stay alert to their surroundings and avoid potential predators while they sleep.

Do Cockatiels Need Light at Night?

Reasons Why Cockatiels Need Darkness at Night

Cockatiels, like all diurnal birds, require darkness at night to get adequate sleep. Exposure to light during the night can disrupt their sleep cycle and lead to health problems such as fatigue, restlessness, and irritability. In their natural habitat, cockatiels sleep in trees or other protected areas where it is dark and quiet. As a pet owner, it’s important to replicate this environment as closely as possible to ensure that your cockatiel gets the rest it needs.

The Negative Effects of Light on Cockatiel Sleep

Exposure to light during the night can cause a variety of negative effects on cockatiel sleep. It can disrupt their natural sleep cycle, which can lead to restlessness and insomnia. Over time, this can weaken their immune system and make them more susceptible to illness. In some cases, exposure to light at night can even cause behavioral problems such as aggression, anxiety, and depression.

The Importance of Proper Lighting during the Day

Why Proper Lighting is Important for Cockatiels

Cockatiels require proper lighting during the day to maintain a healthy circadian rhythm. Exposure to sunlight or full-spectrum lighting helps regulate their sleep cycle, metabolism, and hormone levels. Without adequate light during the day, cockatiels can become lethargic, depressed, and develop health problems such as calcium deficiency.

Types of Lighting for Cockatiels

When it comes to lighting for cockatiels, there are several options available. One of the best sources of light is natural sunlight. If possible, place your cockatiel’s cage near a window that gets plenty of sunlight. However, it’s important to ensure that the cage is not in direct sunlight, which can cause overheating and discomfort for your bird. Another option is full-spectrum lighting, which provides a balanced spectrum of light that mimics natural sunlight. Full-spectrum lighting is especially important during the winter months when natural sunlight is limited.

Tips for Creating a Good Sleeping Environment for your Cockatiel

Choosing the Right Cage

When choosing a cage for your cockatiel, it’s important to select one that is appropriate for their size and needs. A good cage should be spacious enough for your bird to move around freely and have plenty of room for toys and perches. It should also be made of sturdy materials and have a secure lock to prevent escape.

Positioning the Cage

The position of your cockatiel’s cage can also affect their sleep quality. Ideally, the cage should be placed in a quiet, dark room away from any sources of noise or light. Avoid placing the cage near windows or doors where your bird may be exposed to drafts or fluctuations in temperature.

Using Covers or Curtains

Using a cover or curtain over your cockatiel’s cage can help create a dark and quiet sleeping environment. Covers or curtains should be made of breathable material and fit snugly over the cage to prevent light from entering. However, it’s important to ensure that your bird has adequate ventilation and air circulation, even with the cover or curtain in place.


In conclusion, cockatiels do not need light at night and require darkness to get adequate sleep. Proper lighting during the day is essential for maintaining a healthy circadian rhythm and preventing health problems. When creating a sleeping environment for your cockatiel, it’s important to choose the right cage, position it in a quiet, dark room, and use covers or curtains to create a cozy and comfortable sleeping space. By following these tips, you can help ensure that your cockatiel gets the rest it needs to stay healthy and happy.
