The Lord Howe Woodhen was formally described by Sclater as Ocydromus sylvestris (Proc. zool. Soc. Lond. 1869: 472). It is a medium-sized, flightless rail that inhabits the forest floor on Lord Howe Island. It has a body length of 30 to 40 cm (males 34 to 42 cm; females 32 to 37 cm) (Fullagar 1985). Adults weigh between 450 and 500 grams; males are typically 15% heavier than females and lowland birds 25% heavier than those on Mount Gower (R. Harden, NPWS, pers. comm.). It is generally dull olive brown with paler markings around the face (including grey flecks in birds > 7 yrs old). The primaries and secondaries (flight feathers) are bright chestnut with fine black barring. The Woodhen's pinkish-grey bill is slender, down-curved and slightly shorter or the same length as the head. Its legs are thick, with a pinkish grey-brown tarsus between 40 and 57 mm long (Marchant and Higgins 1993).
