| Research Abstract |
In order to clarify the mechanisms of the structural colors of bird feathers, we have investigated microstructures and optical properties of the feather of several species of birds including the rock dove and peacock. In particular, for rock dove, several structural elements have been carefully characterized and the comprehensive mechanisms of the structural coloration have been elucidated. In addition, it has been found that the peculiar visual effects are realized by the correspondence between the spectral line shape and the color sensitivities of vision.
