Behavior
These birds hunt by waiting from a high exposed perch often at the top of the tree. They fly out to catch the flying insects and return to the same perch. The flycatchers usually catch insects in mid-air and consume them whereas larger preys are carried back to the perch.
Breeding and Nesting
Nests in the shape of a flat open cup, made up of twigs, lichens, rootlets, grass, weeds are built by the female on horizontal branches away from the trunk. These monogamous birds display courtship behavior involving brisk chasing through the branches. They have a large breeding territory that can extend to 40-45 hectares around the nest, with the male aggressively defending the territory.
