The Australasian swamphen (Porphyrio melanotus) is a species of swamphen (Porphyrio) occurring in eastern Indonesia (the Moluccas, Aru and Kai Islands), Papua New Guinea, Australia and New Zealand. In New Zealand, it is known as the pukeko (from the Māori pūkeko). The species used to be considered a subspecies of the purple swamphen.
The New Zealand population (along with green-yellow swamphens in Tasmania) are possibly slightly larger than mainland Australian birds, but are otherwise identical. When threatened, they will often walk away from danger rather than fly. When they fly, take-offs and landings are clumsy, and short flight distances are preferred.
