Lord Howe Woodhen

Hypotaenidia sylvestris

IncreasingENAUENAU

Overview

This flightless rail is endemic to Lord Howe Island, a small volcanic remnant in the Tasman Sea off the eastern coast of Australia. Adults display olive-brown and chestnut plumage with dark barring on the flanks, short wings, and a stout reddish bill. As a ground-dwelling forager, the species feeds on invertebrates, seeds, and fallen fruit, playing a role in leaf-litter turnover and seed dispersal within the island's forest ecosystem.

It is territorial and monogamous, nesting on the forest floor.

Historically restricted to the island's misty upland forests after being extirpated from lowland areas, the woodhen occupies subtropical moist lowland and montane forest, as well as riparian corridors along permanent streams. Its total range remains confined to Lord Howe Island and adjacent marine waters.

The species' near-extinction resulted from introduced predators, particularly feral pigs, cats, and rats, which destroyed nests and killed adults, compounded by historical hunting by sailors and settlers for food. Ongoing threats include residual predation pressure from invasive species, competition or disturbance from other native species, and habitat degradation linked to logging.

Intensive conservation intervention beginning in the 1980s included a captive breeding program, systematic removal of feral pigs and goats, and sustained rodent control. These measures enabled reintroduction across the island and recovery from a low of under 30 individuals to a population now numbering several hundred.

The population trend is currently increasing, reflecting the success of predator control and habitat protection. However, the species remains classified as Endangered due to its extremely restricted range and continued vulnerability to potential incursions of invasive species or disease outbreaks, making sustained biosecurity vigilance essential to its long-term persistence.

The Lord Howe Woodhen has historically been threatened by hunting and trapping, as well as ongoing pressure from introduced predators and competitors like pigs, cats, and rats that prey on birds, eggs, and chicks. Native species can also pose problems, and past clearing of forest for timber has reduced their habitat. These threats are currently considered stable, largely due to sustained conservation and predator-control efforts on the island.

Frequently asked questions

Why is Lord Howe Woodhen classified as Endangered?
Lord Howe Woodhen is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. The Lord Howe Woodhen has historically been threatened by hunting and trapping, as well as ongoing pressure from introduced predators and competitors like pigs, cats, and rats that prey on birds, eggs, and chicks. Native species can also pose problems, and past clearing of forest for timber has reduced their habitat. These threats are currently considered stable, largely due to sustained conservation and predator-control efforts on the island.
Where does Lord Howe Woodhen live?
Lord Howe Woodhen occurs in Australia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
