Anas aucklandica (Auckland Teal)

Synonyms: Anas aucklandica aucklandica; Nesonetta aucklandica

Wikipedia Abstract

The Auckland teal or Auckland Islands teal (Anas aucklandica) is a species of dabbling duck of the genus Anas that is endemic to Auckland Islands south of New Zealand. The species was once found throughout the Auckland Islands but is now restricted to the islands that lack introduced predators: Adams Island, Enderby Island, Disappointment Island and a few smaller islands. An old report of "the same flightless duck" on North East Island, The Snares group most likely refers to a straggler.
