WebApr 12, 2024 · The crystallinity of the keratin in the belly feathers has been shown, by X-ray diffractometry, to decrease on wetting, producing dimensional changes. It is thought that variations in the crystallinity within the barbules, on wetting, could lead to the uncoiling of the helices of the barbules in the inner zone and the rotation of those barbules ...
