“…Bonobos may show interest in another individual's food by peering from close range at the item or the possessor, often almost touching the possessor's face ( Fig. 1) (Furuichi 1989;Idani 1995;Johnson et al 1999;Stevens et al 2005); or a beggar may reach for the resource using their hands (Fruth and Hohmann 2002).…”

Food begging and sharing in wild bonobos (Pan paniscus): assessing relationship quality?

et al. 2016

Food transfers are often hypothesised to have played a role in the evolution of cooperation amongst humans. However, they also occur in non-human primates, though no consensus exists regarding their function(s). We document patterns of begging for food and success rates as well as associated factors that may influence them for wild bonobos at LuiKotale, Democratic Republic of Congo. Our data, collected over 1074 observation hours, focus on 260 begging events (outside mother-offspring dyads) of which 37 % were successful. We find no support for the "reciprocity hypothesis"-that food is exchanged for grooming and/or sexual benefits; and only weak support for the "sharing under pressure" hypothesis-that food is transferred as a result of harassment and pays off in terms of nutritional benefits for the beggar. Instead, our data support the "assessing-relationships" hypothesis, according to which beggars gain information about the status of their social relationship with the possessor of a food item. This seems to hold particularly true for the frequent, albeit unsuccessful begging events by young females (newly immigrated or hierarchically non-established) towards adult females, although it can be observed in other dyadic combinations independent of sex and age.

“…Rather than signaling subordination, peering seems to indicate interest in these resources or commodities, perhaps without the intention of obtaining them. For example, Johnson et al [1999] reported a change in peering direction between two female bonobos after one of them gave birth, which may simply indicate that the dominant female of the two was showing interest in the infant involved.…”

“…Peering is a highly ritualized behavior in which the actor stares at the receiver's face from a very close distance (up to a few centimeters) [Furuichi, 1989;Idani, 1995;Kano, 1992Kano, , 1996. Johnson et al [1999] suggested that peering functions as a ''signal acknowledging female status.'' In agreement with results from field studies [Furuichi, 1989], Johnson et al [1999] found that peering was mostly directed at older females.…”

“…Thus we analyze 1) the linearity of the peering order, 2) the unidirectionality of peering within the dyads, 3) the correspondence of ranks based on peering and agonistic behavior, and 4) the consistency of a peering order across contexts. We also study the distribution of peering in the study groups to determine whether peering is indeed more directed at older, high-ranking females (Johnson et al, 1999), by examining the relation between peering and the variables, age, rank, and sex.…”

Peering is not a formal indicator of subordination in bonobos (Pan paniscus)

et al. 2005

View full text Add to dashboard Cite

It has been suggested that peering behavior in bonobos is a formal signal acknowledging social dominance status. We investigated whether peering meets the published criteria for a formal signal of subordination in five captive groups of bonobos. The degree of linearity in the set of peering relationships was significantly high in all study groups, and a linear rank order was found. However, unidirectionality was low, and there was little correspondence between the peering order and the agonistic dominance rank. Therefore, peering does not satisfy the criteria of a formal subordination indicator. We also studied the relation between peering and agonistic dominance rank, age, and sex. Animals directed peering significantly more often at high-ranking animals in four of the groups. We suggest that peering is indirectly related to dominance rank by the resource-holding potential of individuals. In contexts where dominant individuals can monopolize resources, peerers may direct their attention at those high-ranking animals. When resources are distributed more evenly, high-ranking animals may peer down the hierarchy. We speculate on the reasons why a formal dominance or subordination signal appears to be absent in bonobos. Am. J. Primatol. 65:255-267, 2005.
