The lighting in a bird aviary should be designed to mimic natural sunlight as closely as possible. This means providing a full spectrum of light, including UVB rays, to support the birds' physical and psychological well-being. It's important to create a day-night cycle with gradual transitions to simulate the natural rhythm of the sun. Additionally, providing areas of shade and dimmer lighting can help birds regulate their activity and rest patterns. Overall, the lighting design should prioritize the birds' health and natural behaviors. **
