. The Biological bulletin. Biology; Zoology; Biology; Marine Biology. FIG. 5. Feathers of Fig. 4, a, b, c, d, before castration, and a1, b1, c1, d1, after castration on Sept. 15, and a2, b2, c2, d2, on March 3, 1920. The feathers of the shoulder (wing-bow), of the hen-feathered male are barred with broad bars, Fig. 3, d. After castration the barring is lost, the outer ends of the feathers become pure white, and on each side barbules are lacking over a broad zone. This change, also, is towards cock-feathering as seen by comparing. Please note that these images are extracted from scanned page im
