Sounds and Vocal Behavior


Lettered Aracari is not particularly vocal (Hilty and Brown 1986, Ridgely and Greenfield 2001b, Short and Horne 2001). The primary vocalization of Lettered Aracari is described as "an often long-continued series of guttural cha notes" (Ridgely and Greenfield 2001b); as "a fast series of sharp kkik (or kkuk, or kkek) notes at 2.5 to 3.5 per s, usually in 'strings' of five to 15 notes, punctuated by a double kkek-ek" (Short and Horne 2001); or as a "series of electric grunts: jrnk jrnk jrnk…." (Lane, in Schulenberg et al. 2010).

Lettered Aracari also gives single chak or kak notes (Remsen, in Hilty and Brown 1986, Short and Horne 2001).

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

Nonvocal Sounds

Lettered Aracari also makes a bill rattle, bdddt, at ca 33 elements per second, and of 0.15-0.2 second in duration (Short and Horne 2001). This bill rattle has been elicited following audio playback (Short and Horne 2001), but presumably also is given naturally in antagonistic interactions.
