A large, brightly colored inhabitant of marshes, meadows, and mangroves. Combination of blue body and bright red bill and legs is unmistakable. Can be quite shy, but size and color make it unmistakable when it emerges from vegetation. Like many other rails, gives a range of call notes, including rattles, squeaks, and grunts. Very similar to the closely-related Gray-headed Swamphen, with which its range overlap is minimal; exact identifying factors are unclear but has a generally darker body.
