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.

Likely
About 50% of wildlife watchers report a Dusky Moorhen sighting in Sydney on a given day, based on 9,307 verified sightings from GBIF citizen-science data. It is the 12th most-seen of the 243 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
December to October
In those months about 50% of wildlife watchers report a Dusky Moorhen in Sydney on a given day, against about 40% in November, the lowest month.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Dusky Moorhen sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 cities where we can rate Dusky Moorhen sightings, Sydney ranks 4th at about 50%. The best odds are in Brisbane (Australia, about 60%), Melbourne (Australia, about 60%) and Perth (Australia, about 50%).
Same family: Rallidae
The closest relatives of the Dusky Moorhen that you can see in Sydney (family Rallidae, Rails, Gallinules, and Coots) are Eurasian Coot (about 40%), South-west Pacific Swamphen (about 30%) and Buff-banded Rail (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dusky Moorhen is recorded against all the birds logged in Sydney (9,307 verified sightings), 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.
