Fig. 2. (A—G) Normalized pre-bleach (filled squares) and post-bleach (open circles) absorbance spectra of visual pigments in the peafowl Pavo cristatus. Pre-bleach spectra are overlayed with best-fitted rhodopsin templates (bold line; Govardovskii et al., 2000). Post-bleach spectra are fitted with a variable point running average (thin line). (H) The spectral distribution of the wavelengths of maximum absorbance (_max) of the individual cone visual pigment absorbance spectra used to create the mean spectra. The group labeled as LWS in the histogram includes LWS single cones and both the principal and accessory members of the LWS double cone pair. VS, SWS, MWS and LWS refer to violet, short wavelength, medium wavelength and long wavelength sensitive single cones, respectively.
