Light may be the cure for what's ailing your bird. SUNLIGHT POWERS ALL LIFE ON earth, either directly or indirectly. Plants obviously must have sunlight or full-spectrum artificial light to manufacture their food by photosynthesis. Plants, in turn, pass on their energy to the animals that consume them. Light is also essential for the survival of most animal species. Animals that have evolved in total darkness (cave dwellers or deep-sea life. for example) do not require light, but nocturnal animals require low-level light.
