The
Auckland 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 (Hector, 1896) most likely refers to a straggler.
The Auckland Teal is smaller and raker than the
Brown Teal of the main islands of New Zealand, a species with which it was once considered
conspecific. The
plumage is all over brown with a hint of green on the neck and a conspicuous white eyering. The female is slightly darker than the male. The wings are very small and the species has, like the related
Campbell Island Teal, lost the power of
flight.
The Auckland Teal is mostly
crepuscular to
nocturnal, preferring to hide from predators (
New Zealand Falcons and
skuas) during the day. The species inhabits a variety of habitats with the islands, including tussockgrass fields, megaherb shrubland and coastal waters. It is carnivrous for the most part, feeding on marine invertebrates,
insects,
amphipods and other small Invertebrates. The Auckland Teal are territorial and seldom form flocks.
