Series of soft, evenly pitched short whistled/nasal notes typical of the genus; heard far more than seen. Note ongoing taxonomy/English-name debate (SACC proposal to call it 'Paria Antpitta'). Recordings on Xeno-canto and Macaulay Library under 'Grallaricula cumanensis' (eBird code slcant5) - sample relatively thin, so log any recordings.
