The white-winged chough (Corcorax melanorhamphos) is one of only two surviving species of the Australian mud-nest builders family, Corcoracidae, and is the only member of the genus Corcorax. It is native to southern and eastern Australia and is an example of convergent evolution as it is only distantly related to the European choughs that it closely resembles in shape, and for which it was named.
The white-winged chough was first described by French naturalist Louis Pierre Vieillot in 1817 as Coracia melanorhamphos, other names given include Pyrrhocorax leucopterus by Dutch zoologist Coenraad Jacob Temminck in 1820, and Corcorax australis by French naturalist René Lesson in 1830. before the current name was settled by Gregory Mathews in 1912. The specific epithet is derived from the Ancient Greek words melano- 'black' and rhamphos 'beak'.
It is placed in the family known as the mud-nest builders or Corcoracidae, written as Grallinidae in older books before the removal of the genus Grallina to the family Monarchidae. It is one of two remaining species, with the apostlebird (Struthidea cinerea), which differs in appearance but exhibits many behavioural similarities. The... Wikipedia →

GBIF citizen-science records
It is estimated from how often the White-winged Chough is recorded against all the birds logged in Kosciuszko National Park (73 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.
