The Australasian swamphen (Porphyrio melanotus) is a species of swamphen previously considered a subspecies of the purple swamphen. Members of this species live in groups of 3–12 individuals and are known to group together and shriek loudly to defend nests successfully during attacks; when unsuccessful at repelling predators, they may abandon their nest sites. The Australasian swamphen can be found in eastern Indonesia (the Moluccas, Aru and Kai Islands), as well as in Papua New Guinea, Australia, and New Zealand.Photograph: Toby Hudson
