Colours in flight — pigments from bird feathers and butterfly wings [N. Krishnaswamy, C. Sundaresan] Among the most colourful objects found in Nature are bird feathers and butterfly wings. Their beauty is more obvious when a bird or a butterfly is in flight as the colour of the pigments present in wings and feathers is accentuated by refraction and reflection of incident light by the nanokeratinoid structural elements in the feather. Thus, when a bird or a butterfly flaps its wings the effect is kaleidoscopic. The pigments responsible for the primary colours of bird feathers and butterfly wings are discussed here.
