The black-crowned monjita is a conspicuous tyrant flycatcher that often perches on fence posts and shrubs in open country, sallying out to catch insects. It undertakes austral seasonal movements, with some populations shifting northward in the non-breeding season. Its bold black crown contrasts with otherwise pale plumage, making it easier to identify at a distance.
Temperament
alert and perching, moderately territorial
Flight Pattern
short rapid wingbeats with quick sallies
Social Behavior
Typically seen singly or in pairs during the breeding season, defending small territories in open country. Outside the breeding season, loose groups may form in favorable foraging areas. Nests are open cups placed in low shrubs or on small trees, and both sexes may participate in territorial displays.
Migratory Pattern
Seasonal migrant
Song Description
Vocalizations are a series of thin, high-pitched notes and short chatters delivered from exposed perches. Calls are sharp and carry well across open habitats, often given during brief display flights.
