The Tasmanian native hen is a distant relative of the domestic hen and is found only in Tasmania. Like the thylacine and Tasmanian devil, native hens became extinct on the mainland around the time the dingo arrived in Australia.
A native hen stands about 45 centimetres (17 inches) tall, has a pale yellow bill and bright red eyes. They are coloured green-brown above and slate-grey on the flanks, with white flashes. Their tail and abdomen are black.
They are very social and make a number of calls including a loud, distinctive rasping 'see-saw'.
Their social structure is unique. Within each population, roughly half are monogamous (have only one mate) and the remainder polygamous (have more than one mate). Juvenile native hens assist with the raising and protection of their brothers and sisters.
Native hens can be seen on most riverside farmlands throughout the State. The Derwent, Tamar, North Esk and South Esk rivers are great places to start. Sightings are guaranteed on Maria Island, where there is a large introduced population.
