Claim Text:
1. A method of illuminating diurnal avians with artificial light sources, the method comprising: supplying a first light having a first spectral content between 380 nm (nanometers) and 780 nm to a substantially enclosed habitat for diurnal avians; supplying a second light having a second spectral content and having at least one local maximum in relative intensity at a wavelength at which a predetermined characteristic visual spectral response of the diurnal avian has a local maximum to a substantially enclosed habitat for diurnal avians, wherein the second spectral content has at least one local maximum in relative intensity that is within 30 nm of the wavelength at which a predetermined characteristic visual spectral response of the diurnal avian has a local maximum and the second spectral content does not have content between 620 nm and 630 nm.
