Porphyrio poliocephalus, John Latham, 1801
Grey-headed swamphen (Porphyrio poliocephalus) is a species of swamphen occurring from the Middle East and the Indian subcontinent to southern China and northern Thailand. It used to be considered a subspecies of the purple swamphen, but was elevated to full species status in 2015; today the purple swamphen is considered a superspecies and each of its six races are designated full species.
The male has an elaborate courtship display, holding water weeds in his bill and bowing to the female with loud chuckles.
The grey-headed swamphen was introduced to North America in the late 1990s due to avicultural escapes in the Pembroke Pines, Florida area. State wildlife biologists attempted to eradicate the birds, but they have multiplied and can now be found in many areas of southern Florida. Ornithological authorities consider it likely that the swamphen will become an established part of Florida's avifauna. It was added to the American Birding Association checklist in February 2013.
