This video from the USA says about itself:
5 December 2016
The rare and exotic Purple Swamphen is an introduced bird species to Florida from southeast Asia. It is like a native Purple Gallinule on steroids – the size of a large chicken and stunning in its purple and green beauty.
A video of the native Purple Gallinule which is much smaller and has different beak coloration can be seen here.
The Purple Swamphen (Porphyrio porphyrio) was added to the ABA Checklist based on a naturalized population found in Florida. Following a 7–0 vote in August 2012 by members of the Florida Ornithological Society Records Committee to add the species to the Official Florida State Bird List, the CLC voted 7–1 to accept the Purple Swamphen as an established exotic. The dissenting CLC voter was concerned that the swamphen population was not large enough to be truly established; CLC rules allow a species to be accepted with one dissenting vote. The addition of Purple Swamphen raises to 977 the number of species on the ABA Checklist.
