It has been observationally confirmed that the color of birds, such as kingfisher and red-flanked bluetail, is a structural color owing to the interference of the light within a sponge structure inside a barb. In this study, we consider the air rod photonic crystal to which disorder is introduced into the translation vectors and the radius as a model of the structural color of red-flanked bluetail; the optical property of the model is numerically analyzed and is compared with that of the structural color.
