The
white-winged chough (
Corcorax melanorhamphos) is one of only two surviving members 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.
