Summary By combining different call types, such as barks with screams, individuals have the potential to vastly increase the range of information that can be decoded by listeners. Few animal studies, however, have examined the information content of call combinations compared with the information conveyed by each call singularly. We examined several aspects of call combinations in the repertoire of wild chimpanzees in the Tai Forest, Ivory Coast, including the types of combinations, the… Expand

Figures and Tables from this paper

Call concatenation in wild meerkats
TLDR
Call combinations produced by wild meerkats in social contexts in their natural habitat suggest that they represent a non-negligible part of meerkat social communication and that they can be used in flexible ways across various behavioural contexts. Expand
Context-related call combinations in female Diana monkeys
TLDR
This study investigated extensively the vocal behaviour of free-ranging and individually identified Diana monkeys in non-predatory contexts and demonstrated that some non-human primates are able to increase the effective size of their small vocal repertoire by varying the acoustic structure of basic call types but also by combining them into more complex structures. Expand
Flexible use of simple and combined calls in female Campbell's monkeys
TLDR
It is found that combined utterances were more common when identity was relevant such as in mixed-species associations and during socially important vocal exchanges, and this finding is discussed in the light of current theories regarding the evolution of combinatorial signalling. Expand
Call combinations, vocal exchanges and interparty movement in wild bonobos
The vocal repertoire of nonhuman primates is largely fixed. Individuals produce their species-specific vocalizations from a young age, and do not acquire new call types over their lifetime. DespiteExpand
Wild chimpanzees’ use of single and combined vocal and gestural signals
TLDR
It is found that gesturing peaks in infancy and decreases in older age, while vocal signals show the opposite distribution, and patterns of persistence after failure suggest that gestural and vocal signals may encode different types of information. Expand
Campbell's monkeys concatenate vocalizations into context-specific call sequences
TLDR
The results of a long-term study on Campbell's monkeys are presented, which reveals an unrivaled degree of vocal complexity and may be the most complex example of ‘proto-syntax’ in animal communication known to date. Expand
Predator guild does not influence orangutan alarm call rates and combinations
TLDR
Orangutans make a suitable great ape model to assess alarm call composition in relation to the size of the predator guild, and if these results are replicated in other great apes, this indicates that predation did not drive selection towards ever more combinatorial rules in the human lineage. Expand
Dwarf mongoose alarm calls: investigating a complex non-human animal call
TLDR
This study complements previous knowledge of vocal combinatoriality in non-primate mammals and introduces an approach that could facilitate comparisons between different animal and human communication systems. Expand
Call combinations in monkeys: Compositional or idiomatic expressions?
TLDR
This work investigates whether 'pyow-hack' sequences are compositional in that the individual calls contribute to their overall meaning, and whether this communication system enables callers to increase the number of messages that can be conveyed by a small and innate call repertoire. Expand
Segmental concatenation of individual signatures and context cues in banded mongoose (Mungos mungo) close calls
TLDR
This study investigates how banded mongooses (Mungos mungo) encode multiple vocal signatures or cues in their frequently emitted graded single syllable close calls and provides the first evidence of segmental concatenation of information within a single syllables in non-human vocalizations. Expand

Context-specific calls in wild chimpanzees, Pan troglodytes verus: analysis of barks
TLDR
The results show that two strategies for producing context-specific signals seem to have evolved in a species other than humans: chimpanzees produce context- specific bark subtypes and context- Specific signal combinations. Expand
Wild Chimpanzees Produce Group‐Specific Calls: a Case for Vocal Learning?
TLDR
It is suggested that chimpanzees may actively modify pant hoots to be different from their neighbours, providing support for the vocal learning hypothesis. Expand
Syntactic Structures in the Vocalizations of Wedge-Capped Capuchin Monkeys, Cebus Olivaceus
Capuchin monkeys, Cebus olivaceus, combine different types of calls to form compound calls. These compound calls are syntactically organized (i. e. , there is a predictable ordering of call types inExpand
An analysis of the organization of vocal communication in the titi monkey Callicebus moloch.
TLDR
Frequency and temporal measurements from spectrograms of recordings, and differences in their patterns of use, were used to characterize call types of titi monkeys, and hierarchical and sequential mechanisms as generators of vocal sequences are discussed. Expand
Preliminary Vocal Repertoire and Vocal Communication of Wild Bonobos (Pan paniscus) at Lilungu (Democratic Republic of Congo)
TLDR
The aim of this study is to give a preliminary description of the vocal repertoire and a qualitative account of the contextual use of the voices described, which is compared to that of captive bonobos described by De Waal. Expand

A syntactic rule in forest monkey communication
Abstract Syntactic rules allow a speaker to combine signals with existing meanings to create an infinite number of new meanings. Even though combinatory rules have also been found in some animalExpand
Consistency of female choice in the túngara frog: a permissive preference for complex characters
TLDR
It is demonstrated that the patterns of permissiveness observed in the population are paralleled by similar patterns within females, and a broad preference for complex calls in the P. pustulosus species group would permit the evolution of sexually selected call variation through sensory exploitation.
