The Lord Howe woodhen (Hypotaenidia sylvestris ) also known as the Lord Howe Island woodhen or Lord Howe (Island) rail, is a flightless bird of the rail family, (Rallidae). It is endemic to Lord Howe Island off the Australian coast. It is currently classified as endangered by the IUCN.
The Lord Howe woodhen is a small olive brown bird, with a short tail and a downcurved bill. Wings are chestnut with darker bars. The eyes have a red iris.
The species lives in sub-tropical forests, feeding on earthworms, crustaceans, fruit, and occasionally taking the eggs of shearwaters and petrels.
Woodhens mate for life and are usually encountered in pairs. They are territorial and will appear from the forest's understory to investigate the source of any unusual noise. A mated pair will defend an area of approximately three hectares, with offspring being expelled from this area once grown. The population of birds is thus restricted by the amount of available territory.
