Behavior

Behavior

S. tyrannus makes regular soars of ca 10 min at great heights with frequent calls and slow flapping display during midmorning or midday before returning to the forest (Hilty 2003). Hunting relies on perch-hunting: moving from perch to perch, then flying from the perch with great speed in order to ambush its prey (Hilty 2003). Occasionally perches in low branches.

Territoriality

Soaring has a function of territorial behavior, especially in breeding grounds (Thiollay 1989).

Sexual Behavior

Courtship behaviour consists of display flights with contact and roll-overs (Bierregaard 1994).

Social and interspecific behavior

Usually alone but occasionally seen in pairs (Márquez-Reyes and Vanegas 2008).

Predation

No information.
