Abstract:
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 between 380 nm and 780 nm and having at least one local maximum in relative intensity at a wavelength within 15 nm of 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; and wherein at least one local maximum in relative intensity of the second spectral content is above the median relative intensity of local maxima of the second spectral content.
