It has short legs and sits very upright whilst perched prominently. They use a variety of foraging techniques, including hawking from a perch, sallying hovering, gleaning, and flush-pursuiting. They bathe in small pools of water in the afternoon by diving from perches.

The nest is a tiny cup of grasses, roots, fibers and leaves bound together with cobweb and plastered on the outside with egg-bags of spiders. Paradise-flycatchers like all monarch flycatchers, are monogamous and are generally territorial, although in some cases birds may nest close together and defend the nests together against predators.
