Do Budgies Sleep with Their Eyes Open?

Budgies do not typically sleep with both eyes open; however, they may keep one eye partially open while dozing. This behavior is part of a natural survival instinct known as unihemispheric slow-wave sleep, allowing them to remain aware of potential threats even while resting. When they feel safe, budgies will close both eyes during sleep, entering a deeper state of relaxation. It’s essential to provide a secure and quiet sleeping environment to encourage complete relaxation. If you notice your budgie frequently keeping one eye open, it could indicate that they are still assessing their surroundings for safety.
