The microstructure of white feathers predicts their visible and near-infrared reflectance properties

Stuart-Fox, Devi; Newton, Elizabeth; Mulder, Raoul; D'Alba, Liliana; Shawkey, Matthew D.; Igic, Branislav


Research on the optical properties of animal integuments, including fur, feather, skin and cuticle, has focussed almost exclusively on animal-visible wavelengths within the narrow range of 300–700 nm. By contrast, the near-infrared (NIR) portion of direct sunlight, spanning 700–2600 nm, has been largely ignored despite its potentially important thermal consequences. We quantified variation in visible and NIR reflectance and transmission for white body contour feathers of 50 bird species, and...[Show more]
