Australasian Swamphen
Porphyrio melanotus
Conspicuous blue and black waterhen with gigantic red bill and forehead shield. Has large feet and white under tail feathers which it flicks up and down when walking. Occurs in a wide variety of wetland habitats and is a common sight in urban parks. They are very vocal, often making loud crowing calls and a range of other shorter squawks, including a single note squawk at night.
识别特征
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.

分布与栖息地
The Australasian swamphen occurs in mainland Australia, eastern Indonesia, the Moluccas, Aru and Kai Islands, and in Papua New Guinea. It is also found on New Zealand's main islands and in the Chatham and Kermadec Islands. It has a small shield, black upperparts, and a purple throat and breast. P. p. pelewensis (Hartlaub & Finsch, 1872) from Palau, resembles melanotus but has greener upperparts and is smaller. P. p. melanopterus (Bonaparte, 1856) is found from the Lesser Sundas and Moluccas to New Guinea. It is as melanotus but smaller, more variable and less blue in the upperparts. P. p. bellus (Gould, 1820) from Western Australia is as melanotus but has a cerulean blue throat and breast. P. p. samoensis (Peale, 1848) occurs from New Guinea to New Caledonia and Samoa, and is as melanotus but smaller, with a brown tinge on the back.
行为
Australasian swamphens are considered to be the ancestors of several island species including the extinct Lord Howe swamphen and two species of takahē in New Zealand. On islands where closely related species have become extinct or declined due to human interference, such as New Zealand or New Caledonia, this species has established itself relatively recently.
