"American Purple Gallinule," Wikipedia, the free encyclopedia.The American Purple Gallinule (Porphyrio martinicus) is a "swamp hen" in the rail family Rallidae. This is a medium-sized rail, measuring 2637 cm (1015 in) in length, spanning 5061 cm (2024 in) across the wings and weighing 141305 g (5.010.8 oz).Males, averaging 257 g (9.1 oz) in mass, are slightly larger than females, at 215 g (7.6 oz) on average. The adult Purple gallinule has big yellow feet, purple-blue plumage with a green back, and red and yellow bill. It has a pale blue forehead shield and white undertail. Darkness or low light can dim the bright purple-blue plumage of the adult to make them look dusky or brownish, although the forehead shield color differentiates them from similar species such as Common Gallinules.
