Porphyrio poliocephalus
A simple vista
Native to southern Asia, these big marsh birds have been established in Florida since the 1990s. First noted near Pembroke Pines in 1996, the population might have originated with birds that escaped from captivity after Hurricane Andrew in 1992. Now widespread around marshes and ponds in southeastern Florida, where they may number in the thousands. Some authorities treat this bird as a subspecies of the Purple Swamphen, widespread in the Old World from southern Europe to southern Africa and New Zealand.

Comportamiento
Huevos
Each breeding female lays 3-7 eggs, but multiple females may lay in same nest. Eggs are tan or buff with darker brown spots. Incubation is by both sexes, and probably takes about 3 weeks. Young: Fed by adults at first. May start to find some of their own food within a few days after hatching, but adults continue to feed them for several weeks.
Comportamiento alimentario
Forages mostly by wading along shorelines or in shallow marshes or wet fields, sometimes by climbing about in marsh vegetation, occasionally while swimming. Often stands on one foot and uses other foot to grasp plant stems and pull them up to beak.
Dieta
Mostly plant material, including stalks, roots, leaves, and seeds of aquatic plants, especially spikerush in Florida. Also eats some insects, frogs, snails, and other small creatures, or scavenges food scraps left by humans.
