Abstract. One of the most prominent behavioural features of many forest primates are the loud calls given by the adult males. Early observational studies repeatedly postulated that these calls function in intragroup spacing or intergroup avoidance. More recent field experiments with Diana monkeys (Cercopithecus diana) of Taï Forest, Ivory Coast, have clearly shown that loud male calls function as predator alarm calls because calls reliably (1) label different predator classes and (2) convey… 

Lesser spot-nosed monkeys coordinate alarm call production with associated Campbell’s monkeys

The alarm call system of lesser spot-nosed monkeys, a primate that spends most of its time in mixed-species groups while occupying the lowest and presumably most dangerous part of the forest canopy, is analysed, finding evidence for two acoustically distinct calls but, contrary to other primates in the same habitat, no evidence for predator-specific alarms.

Anti-predator behavior of group-living Malagasy primates: mixed evidence for a referential alarm call system

Redfronted lemurs and white sifakas have independently evolved a mixed alarm call system, characterized by functionally referential calls for diurnal raptors, but not for carnivores.

The alarm call system of wild black-fronted titi monkeys, Callicebus nigrifrons

Recorded natural predator responses from five different groups of black-fronted titi monkeys suggest that calls A and B provide listeners with rapid and reliable information about the general classes of danger experienced by the caller, while obtaining more specific information through other call types and combinations and behavioural responses.

Anti-predator behaviour of black-fronted titi monkeys (Callicebus nigrifrons)

The main goal of this chapter was to present a first summary description of the main calls of black-fronted titi monkeys during encounters with live and with stuffed predator species.

Production and perception of situationally variable alarm calls in wild tufted capuchin monkeys (Cebus apella nigritus)

Investigating the alarm call system of tufted capuchin monkeys by examining responses to predator and snake decoys encountered at various distances adds to the evidence that functionally referential aerial predator alarm calls are ubiquitous in primates, but that noncatarrhine primates use generalized disturbance calls in response to terrestrial threats.

A forest monkey’s alarm call series to predator models

Observations of these same call series given in non-predatory contexts indicate that predator class is unlikely to be the relevant organising principle underlying the alarm-calling behaviour in this species, and offers an alternative, non-referential, account of the alarms exhibited by this species.

Anti-predator strategies of free-ranging Campbell's monkeys

It is concluded that Campbell's monkeys display sex-specific anti-predator behaviours, which are largely driven by the predators' hunting techniques, mode of predator detection and the forest habitat structure.



Diana monkey long-distance calls: messages for conspecifics and predators

It is concluded that, in addition to their function in perception advertisement, diana monkey long-distance calls function as within-group semantic signals that denote different types of predators.

The Predator Deterrence Function of Primate Alarm Calls

It is concluded that the high alarm call rates to leopards are part of an anti-predator strategy in primates that may have evolved to deter predators that depend on surprise.

Causal knowledge of predators' behaviour in wild Diana monkeys

Results were consistent with the hypothesis that monkeys responding cryptically to chimpanzee alarm calls did so because they were not able to understand the calls' meaning, and with three possible cognitive mechanisms, associative learning, specialized learning programmes, and causal reasoning, that could have led to causal knowledge in some individuals but not others.

Causal cognition in a non-human primate: field playback experiments with Diana monkeys

Referential labelling in Diana monkeys

Analysis of male and female alarm-call behaviour showed that Diana monkeys consistently responded to predator category regardless of immediate threat or direction of attack, and suggested that, in addition to predator categories, monkeys' alarm calls might also convey information about the predator's distance.

Experimental playbacks show vocal mediation of intergroup avoidance in a forest monkey

DISTINCTIVE vocalisations, audible over long distances, have been reported among many forest primate species, ranging from prosimians to apes1–5. Such loud calls have often been hypothesised to

Comparisons with data on grouping patterns from Gombe and Mahale chimpanzees living in more open habitats support the hypothesis that this species adapts itself to leopard predation which is known to be lower in savanna habitats.
