Sounds and Vocal Behavior


The song of Castelnau's Antshrike is described as "an accelerating, descending series of downslurred notes: kyuk kyuk-kyew-kew-kew'ku'ku'kukuku" (Lane, in Schulenberg et al. 2007), with a nasal, bouncing-ball quality (Ridgely and Greenfield 2001b). The number of notes given may vary between successive songs (Zimmer and Isler 2003).

For a representative audio recording with sonogram, see audio

Calls include "a cawing raow; a similar bark-rattle, the rattle rising in pitch: raow-brrrrrrrrr; and a down-slurred mewing aww, often doubled" (Lane, in Schulenberg et al. 2007).

Additional recordings of Castelnau's Antshrike vocalizations can be heard at Macaulay Library and at xeno-canto.
