Light influences all animals. Natural light sources come from rays directly off the sun and stars or rays reflected by the moon. Numerous sources of artificial light occur in indoor dwellings. Lighting like full spectrum mimic the light energy from the sun and causes the same physiological results in animals.
In my opinion birds (and humans), more than any other species, are profoundly affected by light because they rely on sensory input from their eyes. Light affects birds in many ways. Birds obtain vitamin D3 from both diet and synthesis in their skin. The synthesis of vitamin D3 in the skin requires ultraviolet (UV) light.
This UV light stimulates
oils secreted by the uropygeal gland near the base of the tail and the
oil is converted to vitamin D3. When your bird preens they are ingesting
infection. Sunlight stimulates male songbirds to sing. Light has a profound
effect on avian reproduction behavior also. Molting is also affected
Full spectrum lights
are available in many places today. I will tell you they are not cheap!
The benefit you and your birds will receive from them is worth the price.
One place I know where you can get these lights, and also get some great
information on the lighting, is Light Energy Company in Seattle, Washington.
Their toll-free phone number is 1-800-544-4826 or local 206-542-7612.
