It feeds mainly on flying insects, such as dragonflies and butterflies. Alone or in pairs in wetlands or forests. Nesting is exquisite, and the chicks are late
Nests usually hang from branches and vines and breed from January to April, with chicks born in Rio de Janeiro, indicating that farming takes place in the spring; in the Southern Hemisphere it is September to October.
