Breeding
The nest is a round cup made from intertwined fine plant fibres bound with spider webs, situated in a fork near the end of a thin horizontal branch in a tall tree. 1-3 eggs are laid and incubated for 16-18 days; the young fledge after 15-19 days. Juveniles are dependent for at least several weeks after fledging, and then remain with their parents until at least the following breeding season.
Diet
The diet includes insects and small vertebrates such as geckos or lizards.
Perches upright with tail hanging vertically below. Hawks insects on the wing while gliding from observation post.
