Sounds and Vocal Behavior

Vocalizations

The song of Scaled Antpitta is a rapid series of quavering, hollow notes lasting 2-7 seconds, slowly increasing in volume and pitch and then quickly becoming quieter at the end: cau, cau, cau-cau-caucaucaucau, cau. Krabbe & Schulenberg (2003) provide a detailed description of the song of regulus, stating that songs generally include 30-50 notes delivered so quickly (i.e. 14-17 per second) that it generally sounds like fewer. Delivery pace, after a few introductory notes, is rapid in the beginning, slowing towards the end.

Krabbe and Schulenberg (2003) note that the songs recorded in southern Peru (sororia) differ in having the first portion delivered at a much slower pace (only 6 notes per second), with the entire song slightly longer and being composed of only 18-23 notes; similarly, Lane (in Schulenberg et al. 2010) describes the song of sororia as "a slower-paced (6 notes/sec maximum) series of hooted notes that accelerates-decelerates at the loudest and highest-pitched notes, then accelerates again slightly: poo-poo-pu-pu'pu'pu-pu-POO-POO-POO-pu'pu".

Braun et al. (2003) describe three vocalizations of roraimae. The most frequently heard song was described as a long series of low hooting notes with three longer, more emphatic notes in the middle. They also occasionally heard a higher-pitched and somewhat screech-owl-like song. The third song, given most frequently at dawn, was a shorter-simpler version of the owl-like call described above.

Stiles and Skutch (1989) describe a low, pig-like grunt or croak given in alarm in Costa Rica.

Additional audio recordings of vocalizations of Scaled Antpitta can be heard at Macaulay Library and at xeno-canto.
