Sounds and Vocal Behavior

The song of Bicolored Antpitta is a high, clear, whistled treeeee or treeeeeuh. Apparently, the female sometimes follows this with a kree-kree-kree-kree-kree-kree (Nilsson et al. 2001, Nilsson in Ridgely and Tudor 2009). The typical song lasts only around a second, and is delivered at intervals of 3-4 sec., at a frequency of around 2 kHz (Krabbe and Schulenberg 2003). The end of the song is usually upslurred and then downslurred (or the reverse).

The presumed "reply" of the female is described by Krabbe and Schulenberg (2003) as a 5-6 second-long delivery of 6-7 whistles, descending from around 2.5 kHz to 2 kHz.

Additional audio recordings of vocalizations of Bicolored Antpitta can be heard at xeno-canto and at eBird/ML collection .
