Taxonomy
The flightless New Zealand species Chenonetta finschi (Finsch's Duck) which was formerly believed to constitute a monotypic genus (Euryanas) has been determined to belong to Chenonetta. It became extinct before scientists could properly survey the New Zealand avifauna, but possibly as late as 1870 (based on a report of a flightless goose caught in Opotiki.)
