Finsch's Duck (Chenonetta finschi) was a large terrestrial species of duck formerly endemic to New Zealand. Year 1930 ( MCMXXX) was a Common year starting on Wednesday (link will display 1930 calendar of the Gregorian calendar. In Scientific nomenclature, synonyms are different Scientific names used for a single Taxon. For duck as a food see Duck (food; for other meanings see Duck (disambiguation. Endemism is the Ecological state of being unique to a place Endemic species are not naturally found elsewhere New Zealand is an Island country in the south-western Pacific Ocean comprising two main landmasses (the North Island and the South Island The species was possibly once the most common duck in New Zealand, a supposition based on the frequency of its fossils in bone deposits. FOSSIL is a standard protocol for allowing serial communication for Telecommunications programs under the DOS Operating system. The species was originally considered to be in its own genus, Euryanas, but is now known to be closely related to the Australian Wood Duck and recently derived from that species. A genus (plural genera from Γένος Latin genus "descent family type gender" is a low-level Taxonomic The Australian Wood Duck or Maned Duck, Chenonetta jubata, is a Dabbling duck found throughout much of Australia.

The Finsch's Duck was much larger than the Australian Wood Duck, probably weighing twice as much (around 1-2 kg) and having larger legs. The wings were much reduced however, and it seems that flight was lost relatively quickly after the species arrived in New Zealand. Little is known about the biology of the species, but its remains have been found widely in New Zealand and it does not seem to have been tied to water like many other duck species.
The species is thought to have become extinct due to human hunting and predation by introduced species, particularly rats. Hunting is the practice of pursuing Animals for Food, Recreation, or Trade. An introduced species (also known as naturalized species or exotic species) is an Organism that is not indigenous to a given location but Like many large flightless New Zealand birds its remains have been found in Māori middens.

A midden, also known as a kitchen midden, or a shell heap, is a dump for domestic waste. Radiocarbon dating puts the youngest bones of the species as recently as the 15th -17th centuries, and one account of a large flightless goose killed in Opotiki suggests the species might have survived until 1870. Radiocarbon dating is a Radiometric dating method that uses the naturally occurring Radioisotope Carbon-14 (14C to determine the age of Opotiki is a town in the eastern Bay of Plenty in the North Island of New Zealand.
