The genus name Tadorna comes from Celtic roots and means "pied waterfowl". They have a striking chestnut-coloured breast and black body. They are protected under the National Parks and Wildlife Act 1974.
William Jardine and Prideaux John Selby described the Australian shelduck in 1828. The males are mostly dark, with a chestnut breast. They have white neck collars and dark green heads.

GBIF citizen-science records
It is estimated from how often the Australian Shelduck is recorded against all the birds logged in Hattah-Kulkyne National Park (86 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.
