Physical description Click here for a physical description Black-tailed Native-hens are medium-sized waterhens. Their plumage is partly grey (head, neck, breast), brownish grey at the back (mantle, wings) and black (belly, vent, tail). They have a small number of white flank spots. The only minute difference between the sexes is that males have a somewhat darker face than females. Both sexes have pale irises. The bill is yellowish-green, with an orange base to the lower mandible. Legs and feet are bright orange. Black-tailed Native-hens have an upright tail, similar to an Australian Brush-turkey's. Twitcher's tip Compared to Tasmanian Native-hens, Black-tailed Native-hens have more conspicuous orange legs and a longer tail.

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 Black-tailed Native-hen is available HERE . Black-tailed Native-hens are endemic to Australia. Their distribution across the Australian continent is complex and highly variable, depending on climatic conditions. They occur mostly in the semi-arid interior of the continent (the Murray-Darling Basin, the Lake Eyre Basin, the eastern half of SA and the southern half of QLD), but are not found in the most arid part of the continent, i.e. the sandy deserts from the Nullarbor to the Kimberley. They occur in WA along the West and South coast (with the exception of the extreme south-western tip) and along the Fitzroy River. They are not found along the Top End (NT, Gulf of Carpentaria, Cape York peninsula), the East coast and the Great Dividing Range of the continent. Black-tailed Native-hens can be found in and around swamps and marshes and in ephemeral wetlands, especially in mudflats, often surrounded by tall reeds and lignum. They are very well adapted to semi-arid environments and need very little; peace and quiet and a single lawn sprinkler can keep a covey in place in an otherwise parched landscape (as observed by us at the camp ground of the - at the time closed - Burren Junction Bore Bath, Burren Junction, NSW).

Sightings Click here for sighting information Black-tailed Native-hens were first spotted by us around a semi-permanent waterhole 20 km South of Narrabri, in 2006, where a few of them stayed until it dried up. Since then, they are found by us semi-regularly in both permanent and ephemeral wetlands in inland NSW. Often they are seen around lakes, but also around dams and in swamps. There were plenty of Black-tailed Native-hens at Macquarie Marshes NR in April 2011, many of them foraging along Gibson's Way, right by the road side. The largest number of Black-tailed Native-hens we have seen so far (an estimated 500 or more) was at Lake Altiboulka, a shallow ephemeral lake about 95 km East of Tibooburra, NSW, in September 2012. J. Greaves reports spotting Black-tailed Native-hens at Loch McNess, Yanchep NP, 55 km North of Perth, WA, in January 2015. M. Eaton reports finding Black-tailed Native-hens at Bowra Station, near Cunnamulla, QLD, in September 2017. R. Plumtreefound Black-tailed Native-hens at the Montecollina bore, off the Strzelecki Track, SA, in November 2018, and at Lake Cullens, VIC, in December 2018. M. Windeyer reports spotting Australian Spotted Crakes in an ephemeral wetland 20 km West of Gilgandra, NSW, in October 2020, where they were found building a nest at the time.
