Figure 1. This series of evenly spaced click-like notes is the "loudsong" of the White-fringed Antwren (Formicivora grisea). To a human listener, the vocalization does not sound like a song, but in playback experiments, it evokes a similar behavioral response as loudsongs in other Typical Antbirds, e.g. F. melanogaster or Thamnophilus pelzelni: the male appears, utters the same song, and searches nervously for the vocalizing conspecific.

See species account in Zimmer and Isler 2003: "... loudsong a monotonous series of dry or harsh notes repeated at same pitch and pace ...". See also CD of Isler and Whitney 2002, CD 2 Track 18, for a similar sample.
