A discreet tyrant flycatcher of dry woodlands and savannas, the rufous casiornis perches quietly and sallies out to catch insects. It often favors semi-open habitats such as the Cerrado and Caatinga, adapting well to edges and lightly disturbed areas. Its simple, whistled song carries surprisingly far at dawn and dusk.
Temperament
solitary and unobtrusive
Flight Pattern
short rapid wingbeats between perches; quick sallies to snatch prey
Social Behavior
Usually seen alone or in pairs, maintaining small territories within suitable woodlands. Pairs likely form during the breeding season, with a simple cup nest placed in a fork or dense shrub. Both adults typically participate in caring for the young. Outside breeding, it remains quiet and secretive, moving methodically through midstory perches.
Migratory Pattern
Resident
Song Description
Delivers a short series of clear, whistled notes, often repeated with pauses. Calls include soft chips and thin whistles given from exposed perches at dawn and dusk.
