“…Since Kloss' gibbons typically live in a dense forest habitat, a narrow frequency range of their songs best adapted for longrange communication may have been se lected in order to broadcast them over long distances [Whitten, 1980], The occurrence of a 'sound window' in forest habitats has been demonstrated in several previous studies [summarized and reviewed by Waser and Brown, 1984], Therefore, because one main function of adult female songs appears to be for intergroup communication, a distinct and narrow frequency range with little variability must be maintained. Consequently, fre quency may be limited in selection for indi viduality in the Kloss' gibbon and therefore the durational aspects and number of notes per call may be the features manipulated, allowing for individuality in this species.…”

Individuality in the Female Songs of Wild Kloss’ Gibbons (Hylobates klossii) on Siberut Island, Indonesia

Observations and recordings were made of the female songs produced by 4 adult and mated female Kloss’ gibbons (Hylobates klossii) from a site on Siberut Island, the largest island of the Mentawai Island chain in Indonesia. A statistical analysis of song characteristics revealed that individuality occurs throughout the entire song. The implications of these findings, as well as comparisons to similar studies of individuality on other gibbon species, are presented.

“…For example, birds have clearly been shown to adjust their acoustics to habitat [e.g., Brumm, 2004;Slabbekoorn & Smith, 2002]. The influence of forest habitat structure on the acoustical call structure of several nonhuman primate species has been reported [blue monkeys, gray-cheeked mangabeys, vervet monkeys, and yellow baboons: Brown et al, 1995;pygmy marmosets: de la Torre & Snowdon, 2002; Japanese macaques: Sugiura et al, 2006;Tanaka et al, 2006; blue monkeys: Waser & Brown, 1984, 1986. Although many studies have investigated the effects of forest habitat on the acoustic features of contact calls, little information is available on the effects of habitat on call rates or patterns.…”

A major function of contact calls in nonhuman primates is to maintain spatial cohesion among individuals in a group. The risks of spatial/visual separation from the group are likely to affect auditory contact behavior, in particular by increasing the call rate. We tested whether the risk of separation influences coo call emission by investigating the variation in call rate among behavioral contexts in two wild populations of Japanese macaques (Macaca fuscata). We focused on caller activity and the degree of visibility within the habitat as primary potential factors mediating call rate. We first estimated the habitat visibility of the two research sites at Yakushima Island (YK) and Kinkazan Island (KZ), Japan. The habitat visibility of YK was significantly more restricted than that of KZ. We then compared the call rate of 20 adult and 12 juvenile female macaques between the two wild populations to examine the potential effects of environmental differences. Both populations had a lower call rate during grooming than during feeding and moving, which are behaviors associated to higher interindividual distances. The call rate of YK adult females was significantly greater than that of both juveniles and KZ adult females, independently of activity. The call rate increased as macaques matured in the YK population, but not in the KZ population, suggesting that different developmental processes involved in contact calling of the two populations. Our findings suggest that separation risk influences call rate, and also imply a possibility of social influence that social structure change effects on the call rates.

“…Spectral energy is concentrated at frequencies between 100 and 1000 Hz (Whitehead 1987). Attenuation in the upper forest strata is low in this frequency range, leading some to hypothesize that calls within this range are particularly well suited for longdistance communication (Wiley & Richards 1978;Richards & Wiley 1980;Waser & Brown 1984). Thus far, most functional explanations of primate long-distance calls have focused on their role in intraspecific communication (Byrne 1982;Kinzey & Robinson 1981;Sekulic 1982;Snowdon 1986;Tenaza 1989;Gautier & Gautier 1977;Waser 1978).…”

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

1997

Abstract. Primate long-distance calls have typically been interpreted as communication signals between conspecific groups (the 'resource defence hypothesis'), but their potential role as anti-predator alarm calls has received comparably little attention. Male diana monkeys, Cercopithecus diana diana,in the Taï forest of Côte d'Ivoire often utter long-distance calls, either spontaneously or in reaction to a variety of stimuli, including predators and non-predators. The present study focuses only on predation contexts and provides evidence for communication to both predators and conspecifics. Males called only in response to predators whose hunting success depends on unprepared prey, that is, leopards and crowned hawk eagles, but not in response to pursuit hunters, such as chimpanzees and humans, which can pursue the caller in the canopy. Calling was regularly combined with approaching the predator. Both observations suggest that male long-distance calls are used to signal detection to the predator ('perception advertisement hypothesis'). Analysis of male long-distance calls given to leopards and eagles showed that they differed according to a number of acoustic parameters. The two call variants were played to different diana monkey groups; conspecifics responded to them as though the original predator were present. We conclude 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.
