A droll little bird, with almost perpetually cocked,wagging tail. Nest a trashy little bag suspended from twig; side entrance and long dangling tail complete disguise. Hops and flutters about, pauses to look up, draws a bead on small insects, then darts up lightening quick in a sally-strike to snap them from beneath leaves (Hilty).
I phographed this bird in Misiones, East Argentina, nesting close to a small river at eye level.
