The watercock (Gallicrex cinerea) is a waterbird in the rail and crake family, Rallidae. It is the only member of the genus Gallicrex. Traditionally held to be closely related to moorhens (which the adult male visually closely resembles), it is actually a member of a mostly tropical Asian clade containing also Aenigmatolimnas, Amaurornis, Himantornis and Megacrex.
