distribution and habitat
The breeding area of the tyrant extends from southern Arizona and the Rio Grande Valley in Texas across Central America to the central area of Argentina and western Peru. Mourning tyrants also occur in Trinidad and Tobago. The breeding birds in the extreme north and south of the range are migratory birds. Otherwise it is a standing bird.
The living space of the mourning tyrants are semi-open landscapes, which are loosely composed of trees and bushes. They have also opened up human settlement space and occur in gardens and along streets.
behavior
Mourning tyrants are pure insectivores who often look out for prey from very high perch. The insects are usually caught in the air. They defend their territories very aggressively against birds that are significantly larger than them. The nest is built in trees and is a loosely joined hemisphere. The clutch consists of two to three eggs. The shell color of the eggs is cream with reddish brown speckles. The female breeds alone. The young birds leave the nest 18 to 19 days after hatching.
