      abstract     = {Birds-of-paradise are nature’s prime examples of the
                      evolution of color by sexual selection. Their brilliant,
                      structurally colored feathers play a principal role in
                      mating displays. The structural coloration of both the
                      occipital and breast feathers of the bird-of-paradise
                      Lawes’ parotia is produced by melanin rodlets arranged in
                      layers, together acting as interference reflectors. Light
                      reflection by the silvery colored occipital feathers is
                      unidirectional as in a classical multilayer, but the
                      reflection by the richly colored breast feathers is
                      three-directional and extraordinarily complex. Here we show
                      that the reflection properties of both feather types can be
                      quantitatively explained by finite-difference time-domain
                      modeling using realistic feather anatomies and
                      experimentally determined refractive index dispersion values
                      of keratin and melanin. The results elucidate the interplay
                      between avian coloration and vision and indicate tuning of
                      the mating displays to the spectral properties of the avian
                      visual system.},
