Anas chlorotis (brown teal)

Synonyms: Anas aucklandica chlorotis

Wikipedia Abstract

The brown teal (Anas chlorotis) is a species of dabbling duck of the genus Anas. The Māori name for it is pāteke. For many years it had been considered to be conspecific with the flightless Auckland and Campbell teals in Anas aucklandica; the name "brown teal" has also been largely applied to that entire taxon. Common in the early years of European colonisation, the "brown duck" (as it had been often referred to) was heavily harvested as a food source. Its numbers quickly fell, especially in the South Island, & in 1921 they became fully protected. Captive breeding & releasing into predator-controlled areas has seen good localised populations re-introduced around the country in recent years.
