Sounds and Vocal Behavior

Vocalizations

Its song is a thin, long trill, which is given often in flight.  Stiles and Skutch (1989) describe the trill as "beginning with a gurgling sputter, dzzhreeeee" and ending with a slide upward.  Low harsh notes express alarm (Stiles and Skutch 1989). Members of a pair utter chirp-like one to two syllable contact calls (Turner and Rose 1989).
