The weka, also known as the Māori hen or woodhen (Gallirallus australis) is a flightless bird species of the rail family. It is endemic to New Zealand. It is the only extant member of the genus Gallirallus. Four subspecies are recognized but only two (northern/southern) are supported by genetic evidence.
The weka are sturdy brown birds, about the size of a chicken. As omnivores, they feed mainly on invertebrates and fruit. Weka usually lay eggs between August and January; both sexes help to incubate.
Weka are large rails. They are predominantly rich brown mottled with black and grey; the brown shade varies from pale to dark depending on subspecies.
The relatively large, reddish-brown beak is about 5 cm long, stout and tapered, and used as a weapon. The pointed tail is near-constantly being flicked, a sign of unease characteristic of the rail family. Weka have sturdy legs and reduced wings.
