Anas aucklandica
The Auckland Teal, *Anas aucklandica*, is a remarkably unique, small, dark-brown dabbling duck endemic to the New Zealand subantarctic Auckland Islands. Males typically feature a subtle iridescent green sheen on the head and a distinct, thin white eye-ring, while females are a duller brown. Measuring between 40-48 cm in length and weighing 500-650 g, this species possesses notably short, stubby wings, rendering it flightless or nearly so - a rare adaptation among ducks. Taxonomically, it belo...
Primarily found in coastal scrub, tussock grasslands, and sedge fens, often utilizing sheltered bays, rocky shorelines, and freshwater streams, typically at sea level or low elevations.
Their diet consists mainly of aquatic and terrestrial invertebrates, including crustaceans (such as amphipods and isopods) and various insect larvae, supplemented by seeds and aquatic vegetation.
Auckland Teals are predominantly nocturnal and crepuscular, actively foraging during the night and resting in dense vegetation by day to avoid potential predators. Their foraging strategy involves dabbling and up-ending in shallow brackish pools, tidal zones, and streams, as well as sifting throu...
The Auckland Teal is strictly endemic to the New Zealand subantarctic Auckland Islands. Its current distribution is confined to several offshore, predator-free islets within the archipelago, specifically Adams Island, Enderby Island, Disappointment Island, and Ewing Island. It is notably absent f...
