Figure 1From: Functional characterization of spectral tuning mechanisms in the great bowerbird short-wavelength sensitive visual pigment (SWS1), and the origins of UV/violet vision in passerines and parrotsUV-visible dark absorption spectrum of the wild type C. nuchalis SWS1. Estimated absorption maximum values (λmax) noted above the dark spectrum. Inset, Dark-minus-acid bleached difference spectra.Back to article page
