Sound and movement are entangled in animal communication. This is obviously true in the
case of sound-constituting vibratory movements of biological structures which generate …

Highlights•Chimpanzees produce low-frequency sounds by drumming on buttress roots of
trees.•Drumming is used across contexts with apparently long-and short-distance functions.• …

We present a novel approach to automatically detect and classify great ape calls from
continuous raw audio recordings collected during field research. Our method leverages …

Animal communication is frequently studied with conventional network representations that
link pairs of individuals who interact, for example, through vocalization. However, acoustic …

Observations of early vocal behaviours in non-human primates (hereafter primates) are
important for direct comparisons between human and primate vocal development. However …

Early-life experiences, such as maternal care received, influence adult social integration and
survival. We examine what changes to social behavior through ontogeny lead to these …

Highlights•Juveniles relied on older individuals about how to best respond to snakes.•Adults
reacted rapidly and only produced alarm calls to dangerous vipers models.•Snake …

Wild chimpanzees drum on tree buttresses during dominance displays and travel,
generating low‐frequency sounds that are audible over distances of more than 1 km …

The arbitrary relationship between signifier and signified is one of the features responsible
for language's extreme lability, adaptability, and expressiveness. Understanding this …

Abstract 'Pant-hoot displays' are a species-typical, multi-modal communicative behaviour in
chimpanzees in which pant-hoot vocalisations are combined with varied behavioural …
