Physical description Click here for a physical description Dusky Moorhens are medium-sized waterhens with dark-grey plumage, with wings and rump having a slight brown tinge. The facial shield and bill are red, the bill having a yellow tip. Male Dusky Moorhens have a more prominent shield than females. The legs and feet of both sexes can have various colours, ranging from olive to scarlet and yellowish-orange. The undertail coverts have two white sides. In-flight, the legs and feet often dangle conspicuously under the tail. Juveniles are more grey than black and have no facial shield or red on the bill yet. Twitcher's tip The difference between a Dusky Moorhen and a Australian (Purple) Swamphen is that the former has two white spots, while the latter has only one on its undertail. This provides birdwatchers with an easy method to distinguish in particular immature birds of the two species.

Taxonomy, classification See Dusky Moorhen at Wikipedia .

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Dusky Moorhen is available HERE . The range of the Dusky Moorhen encompasses eastern Indonesia, New Guinea and Australia. Dusky Moorhens, nominate race "tenebrosa", are endemic to Australia. They populate basically the eastern part of the Australian continent, including northern Tasmania, plus the south-western corner of WA. They are most common along the South and East coast, the Murray-Darling Basin and the Great Dividing Range. After substantial rainfalls they can disperse along the rivers leading into the semi-arid interior, thereby populating about the eastern half of the continent, including the Lake Eyre Basin. In WA they can spread out from the far south-western tip of the continent to populate the western third of the state, to a line from about Esperance, WA, to the Gascoyne. Dusky Moorhens are not found in the eastern two-thirds of WA, most of the NT and the western half of SA. There are no Dusky Moorhens on Cape York peninsula either. Dusky Moorhens live around freshwater lakes, rivers and ephemeral wetlands, often in tall reeds. They are also common in urban parks. Where to look? How to find this species? Dusky Moorhens usually stay close to cover (such as tall reeds) near fresh water. They do not venture as far out into open areas as Australian (Purple) Swamphens.

Sightings Click here for sighting information Race "tenebrosa" We spotted a Dusky Moorhen, race "tenebrosa", for the first time in May 2006 in a park in Sydney, NSW. Since then Dusky Moorhens, race "tenebrosa", are seen regularly by us on fresh water in inland NSW, e.g. at Narrabri Lake, Narrabri, NSW. They are also regularly found elsewhere in the region, often on farm dams with reeds, but also in reeds along slow-flowing creeks. We, and various contributors, have found them in many different kind of freshwater habitats in inland NSW/QLD and along the coastline. They have also been reported to us from the ACT and VIC. J. Greaves reports seeing Dusky Moorhens, race "tenebrosa", regularly in Perth, WA.

Behaviour

Social behaviour: ?

Mobility: Sedentary/dispersive

Elementary unit: Solitary/pair

The name of this species, "tenebrosa" (=timid), indicates that these waterhens are shy. This is why they have a preference for aquatic habitats with tall reeds: They use those reeds for cover. However, in parks they can become used to the presence of humans.

Food, Diet

Dusky Moorhens feed on a variety of (mostly aquatic) plants and small animals.
