Locomotion: Southern Screamers can swim but they prefer to utilize the ground. When threatened, fly up to the tops of trees and trumpet loudly. This species is very good at flying and also at soaring. They are diurnal and  roost in groups in shallow water pools (Carboneras 1992).

Foraging: Southern Screamers are social during the nonbreeding season; they forage in flocks of up to 100 individuals. They mostly graze vegetation but very rarely dig for food (Carboneras 1992).

Sexual Behavior

Pair bond: Southern Screamers form pair bonds that lasts several years and sometimes their whole life.

Courtship display: During the courtship display there is mutual preening and dueting. The head will also is thrown back so it touches the birds’ back (Stonor 1939).

Social and interspecific behavior

Southern Screamers  aggregate in large flocks during the nonbreeding season; they also roost together.  They are solitary during the breeding season and social during the nonbreeding season (Carboneras 1992).
