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. Four subspecies are recognized but only two (northern/southern) are supported by genetic evidence. 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.
