CITES Appendix I. Cattle, rabbits and mice have been eradicated from Enderby Island, and rabbits from Rose Island, leaving all teal-inhabited islands free of introduced mammals. The eradication of pigs and cats from Auckland Island is planned if resources can be sourced. The cost was estimated at $22 million in 2007 and it is not considered likely to take place in the near future (Hyndman 2011). The species has bred successfully in captivity as an aid to the Campbell Island Teal A. nesiotis recovery programme, but no dedicated captive-breeding population is proposed (M. Williams in litt. 1999). Conservation Actions Proposed
Monitor wild populations. Promote the recovery of the species and the importance of predator-free island ecosystems. Promote the removal of predators from the Auckland Islands to allow for future reintroductions (McClelland 1993). Develop a structured captive breeding programme for future reintroductions and supplementation efforts.
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.
The Auckland teal is smaller and rarer 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 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 tussock fields, megaherb shrubland and coastal waters. It is carnivorous for the most part, feeding on marine invertebrates, insects, amphipods and other small Invertebrates. Auckland teal are territorial and seldom form flocks.
