Striking flycatcher with a spectacular mating display, in which male flies high into the air and repeatedly pumps tails above and then below body. Endemic to the Iberá marshes of NE Argentina and E Paraguay. Male unmistakable. Female from other whitish flycatcher by orange throat, pale peach bill, and elongated tail. Prefers flooded grasslands with tall, undisturbed grasses, and is thus threatened by cattle grazing.
