Brown teal

The brown teal (Anas chlorotis; Māori: pāteke) is a species of dabbling duck of the genus Anas native to New Zealand. 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, and in 1921 they became fully protected. Captive breeding and releasing into predator-controlled areas has seen good localised populations re-introduced around the country in recent years.

There are no distinctive differences between a male, female and a juvenile brown teal during non-mating season. They all have a white ring around their eyes as well as a mottled brown colour on their heads and throat. During breeding season the male will begin to change colour, now having a green coloured head, chestnut coloured breast and a white stripe on each side of their body. They will sometimes also have a white clerical neck band. This does vary as some males do tend to be more colourful than others.
