Sounds and Vocal Behavior


Generally silent. Adults use different sounds during the breeding season, copulation, and interactions at feeding aggregations. Nestlings possess calls to express begging, discomfort or defense.


Vocal Development

The begging call is quite sharp in the hatchling but lower-pitched in feathered chicks (16); in fledged young it is loud and can be heard some distance from the nest (2).

Vocal Array

Adults are generally silent at nests (16, 10, 2). During breeding season, however, the species does utter moans, hisses, roars, loud sharp noises, and querulous mewing notes (242, 1, 2). It also gives croaks, hisses, and grunts at carcasses (242, 1). When disturbed, the Cinereous Vulture utters grunting growls, an ascending "kokokoko," pointed "ghighighighi," and high "gli-gli-gli" (243, 1). During copulation, both the male and female make hissing noises, or a droning, whistled "viiiae viiiae" (244, 1, 245).

Nestlings beg using a pitiful, high-pitched "beep" and utter a guttural cackling "güé-güé-güé" to express discomfort (16). During defense, the feathered nestling utters whistled blowing sounds (16, 1, 10, 2).
