The dusky moorhen (Gallinula tenebrosa) is a bird species in the rail family and is one of the eight extant species in the moorhen genus. It occurs in Australia, New Guinea, Borneo and Indonesia. It is often confused with the purple swamphen and the Eurasian coot due to similar appearance and overlapping distributions. They often live alongside birds in the same genus, such as the Tasmanian nativehen and the common moorhen.
John Gould described the dusky moorhen in 1846 from a skin collected along the Murray River in South Australia. Its species name is derived from the Latin tenebrosa "dark". Charles Lucien Bonaparte described Gallinula haematopus in 1856, but this is now a nomen nudum. Gregory Mathews described two subspecies that have been synonymized—magnirostris from Western Australia and subfrontata from New South Wales.
Three subspecies are recognised: subspecies frontata from southeastern Borneo, the Sunda Islands, Timor and western New Guinea, subspecies neumannii from northern New Guinea, and the nominate subspecies from Australia. Common names include dusky moorhen, black gallinule, black moorhen and waterhen.

GBIF citizen-science records
It is estimated from how often the Dusky Moorhen is recorded against all the birds logged in Great Otway National Park (374 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
