This is a monotypic species[1].


Wet lowlands, savanna, estuaries and pool coasts. Observed at heights around 128 m.


Often perches on the top of the trees and other high points, screaming loudly when it perceives danger.

It is a good swimmer but prefers to move on the ground.


The diet consists mostly of plants: stems, seeds, and leaves. They occasionally eat small animals.


Monogamous. The nest is a big platform of reeds, straw and aquatic plants, in inaccessible places. The clutch consists of 2-7 white eggs, which are incubated by both parents for 43 to 46 days. The fledging period takes 8 to 14 weeks.
