    • 1884, Elliott Coues, “§ 4.—An Introduction to the Anatomy of Birds.”, in Key to North American Birds. [], 2nd edition, Boston, Mass.: Estes and Lauriat, →OCLC, part II (General Ornithology), page 180:
      There is a third inner eyelid, highly developed and of beautiful mechanism: this is the nictitating membrane, or "winker" (nictito, I wink), a delicate, elastic, translucent, pearly-white fold of the conjunctiva. While the other lids move vertically and have a horizontal commissure, the winker sweeps horizontally or obliquely across the ball, from the side next the beak to the opposite.
