Sounds and Vocal Behavior

Vocalizations

The song of Jocotoco Antpitta is a slow series of 6-10 (or more) identical notes produced at 0.5-0.6 kHz, and delivered at 1-2 second intervals (Krabbe and Schulenberg 2003). The aforementioned authors suggest that the song of Jocotoco Antpitta is reminiscent of a dog, but my own description would perhaps be more like the distant moo of a cow.

The call is a similarly low, but much softer two-noted ho-co. In alarm both sexes give a similar call, but louder in volume and the second part may be more emphatic and almost double-noted, sometimes ending in a harsh churr and described as a hoó-krrr or a staccato hoó-có-kurr (Krabbe et al. 1999, Heinz 2002, Ridgely and Tudor 2009). These calls are the inspiration for the species’ common name, which is the local onomatopoeic rendition of this jóco-tó-cuorrr. Juveniles make what is apparently a contact call while foraging near adults, as suggested by Heinz (2002). It is described as a slightly drawn-out, single woooo note, easily imitated with a whistle, which is similar in quality to a single note of the common song of Ferruginous Pygmy-owl (Glaucidium brasilianum) (Greeney and Gelis 2005).

Additional audio recordings of vocalizations of Jocotoco Antpitta can be heard at Macaulay Library, at xeno-canto, and at Internet Bird Collection.

Nonvocal Sounds

Agitated adults, while bobbing their heads and running back and forth, make a whooshing sound or subdued clap as they simultaneously flick their wings (personal observations).
