It forages at forest edges and in semi-open habitats.
In Costa Rica, it sallies out to catch insects in the air and also eats fruits of figs, royal palms and mistletoes.
In Golfito, southwestern Costa Rica, it builds bulky domed nests, often on electricity poles. In a 2005–2006 study, most nests were 4–12 m above the ground.
In Golfito, completed nests are sometimes taken over by Piratic Flycatchers.
