Aggressive behaviors and stress related immune weakness can be improved by adjusting the amount of blue light delivered to the subject. One of the great results in applying broad or full spectrum solutions to birds is the increase in endurance, activity, and enhancement of feather condition. Color quality has been demonstrated to be as much an issue as light quantity. Taken together, all of this information leads to the conclusion that unless one is able to provide a consistent unfiltered source of sunlight to avian areas, supplementation through artificial means becomes a responsible consideration. In assuring that birds have access to a well balanced lighting arrangement that provides consistent periods of light, one is also providing the means that the organism needs to remain in balance.
Proper lighting assures the likelihood of a balanced metabolism.
This means that the organism makes good use of nutritional intake, and maintains a normal rate of biological function. While we can never duplicate the benefit of natural environments for birds, we can work to make them as close as possible. By applying quality artificial light sources, a proactive move is in place to achieve balance and consistency in the environment of the bird. It is the responsible action that is called of our stewardship for these wonderful creatures. Ott, John N. 1976.
