Like other screamers, it is a rather sedate bird generally observed singly, in pairs, or in small groups perched on bushes or trees within a marsh or forested swamp. It grazes for herbaceous growth, and builds a nest of aquatic vegetation in the middle of a marsh. The chicks leave the nest after only a few days of brooding.
In our last trip to the East Andes, just by the road, we found this magnificent bird. It made us remember the jurassic time with its dinosaur legs.
