Relationships, adaptations, and habits of the extinct duck ' Euryanas ' finschi | Notornis and Birds New Zealand

[摘要] The relationships, adaptations, and habits of the extinct, endemic Finsch's duck (Anas finschi Van Beneden, 1875) from New Zealand were determined from skeletal comparisons. Finsch's duck, usually placed in the monotypic genus Euryanas Oliver (1930), was found to be most similar to the Australian wood duck (Chenonetta jubata). Because the differences are mainly those associated with loss of flight, Euryanas is synonymised with Chenonetta, and the species should now be known as Chenonetta finschi.
