Examples of normal and super black feather microstructure. a SEM micrograph of Lycocorax pyrrhopterus normal black feather with typical barbule morphology; scale bar, 200 µm. b SEM micrograph of Parotia wahnesi super black feather with modified barbule arrays; scale bar, 50 µm. c Gold sputter-coated normal black breast feather of Melampitta lugubris appears gold. d Gold sputter-coated super black breast feather of Ptiloris paradiseus retains a black appearance indicating structural absorption. SEM stubs are 12.8 mm in diameter. See Fig. 1 for inset photo credits
