“…They also exchanged grooming with the adult male and groomed each other (Fan et al 2006). They even shared meat when 1 female killed flying squirrels (Fan and Jiang 2009). We recorded few cases of agonism among adults during the study.…”

“…FB is likely to be the mother of this juvenile. Our previous study showed that the juvenile slept with FB on 1 night (Fan and Jiang 2008a) and that she always shared meat with him when she killed flying squirrels (Fan and Jiang 2009). The juvenile male usually slept with the adult male at night (Fan and Jiang 2008a), but this study shows that they did not maintain a close spatial relationship throughout the day.…”

Many short-term studies have reported groups of black crested gibbons containing ≥2 adult females (Nomascus concolor). We report the stability of multifemale groups in this species over a period of 6 yr. Our focal group and 2 neighboring groups included 2 breeding females between March 2003 and June 2009. We also habituated 1 multifemale group to observers and present detailed information concerning their social relationships over a 9-mo observation period. We investigated interindividual distances and agonistic behavior among the 5 group members. The spatial relationship between the 3 adult members (1 male, 2 females) formed an equilateral triangle. A subadult male was peripheral to the focal group, while a juvenile male maintained a closer spatial relationship with the adult members. We observed little agonistic behavior among the adult members. The close spatial relationship and lack of high rates of agonistic behavior among females suggest that the benefits of living in a multifemale group were equal to or greater than the costs for both females, given their ecological and social circumstances. The focal group occupied a large home range that was likely to provide sufficient food sources for the 2 females and their offspring. Between

“…Three preliminary studies have described social relationships among the adults in the polygynous western black crested gibbon ( Nomascus concolor ) [Fan & Jiang, ; Fan et al, ; Huang et al, ]. At the Wuliang study site, an adult male and two breeding females formed a stable social group [Fan & Jiang, ]. Both females groomed the adult male and the two females were observed to groom each other [Fan et al, ], feed in the same trees, and sometimes share food [Fan & Jiang, ].…”

In primates, grooming is considered among the most common behaviors for maintaining social bonds; however, to date, few studies have examined grooming behavior in gibbon species in detail. We used both a 5-min interval scan method and social network analysis to study grooming in two groups of polygynous western black-crested gibbon (Nomascus concolor) in Wuliang Mountain, Central Yunnan, China. Individuals in both groups spent little time in social grooming (1.45% and 1.97% of active time). We compared the two groups' grooming networks and found that the group that maintained a more stable social unit had a more complex grooming network while the group with new immigrants had a grooming network characterized by fewer grooming pairs. Females in both groups played important roles in the grooming network. A newly immigrant female spent the most time grooming others and chose the resident adult female as her main adult grooming partner. Other females from both groups chose the adult male as their primary grooming partner (except their offspring). A sub-adult male who had resided in his natal group for 2 years after maturing into an adult also groomed more and was at the center of the network. This male finally replaced the breeding male in his group 3 years after our data collection period ended. We hypothesize that the immigrant female and the resident young adult male engaged in more extensive grooming interactions as a behavioral strategy to gain tolerance from long-term residents. Our results suggest that female gibbons in polygynous groups actively cooperate in maintaining social relationships rather than co-exist through tolerance or avoidance. Our observations indicate that grooming networks in crested gibbons reflect individual dynamics and partly support the social cohesion hypothesis for primate grooming. In this regard, we suggest that changes in gibbon grooming networks can be used to predict social change.

“…Early accounts of wild primates were often purely anecdotal (see examples from the late eighteenth and early nineteenth centuries in Zuckerman []) before animals were habituated and more quantitative methods for data collection became standard (Altmann ; Burghardt ). Some of the most interesting primatological discoveries of the last one hundred years, such as tool use and hunting, came out first in the form of anecdotal accounts (Goodall ) and were then identified and analyzed across the field (on tool use, see Beck ; Breuer, Ndoundou‐Hockemba, and Fishlock ; Galdikas ; Van Schaik, Deaner, and Merrill ; Visalberghi ; Watanabe, Urasopon, and Malaivijitnond ; on hunting, see Butynski ; Fan and Jiang ; Fedigan ; Goffe and Fischer ; Hosaka et al. ).…”

Formal narrative descriptions of primates have long been used by primatologists to describe novel events that are not captured by other data collection methods. However, there has been a shift away from narrative accounts toward more quantitative methods both within primatology and more broadly in the natural sciences.Our objective was to investigate the shifting use of anecdotal evidence in primatology. We systematically reviewed anecdotal accounts published in the four major primatology journals since the year 2000. We found 163 published anecdotal accounts out of 3,960 total articles published between 2000 and 2016. There was an overall decrease in the rates of anecdotes published during this time. Those published covered a wide range of topics and taxa but were skewed toward larger, diurnal primates-in particular, apes. We suggest that anecdotal evidence should continue to be published but that the publication of these data should better reflect the taxonomic diversity of primates. We also suggest potential venues for anecdote publication that may compensate for their loss from formal scientific journals. [narratives, qualitative data, anthropomorphic, primates, observation] RESUMEN Las descripciones narrativas formales de primates han sido utilizadas por largo tiempo por primatólogos para describir eventos novedosos que no son capturados por otros métodos de colección de datos. Sin embargo, ha habido un distanciamiento de los relatos narrativos hacia métodos más cuantitativos tanto dentro de la primatología como más ampliamente en las ciencias naturales. Nuestro objetivo era investigar el uso cambiante de evidencia anecdótica en primatología. Revisamos sistemáticamente los relatos anecdóticos publicados en las cuatro revistas académicas principales de primatología desde el año 2000. Encontramos 163 relatos anecdóticos publicados de un total de 3.960 artículos. Hubo una disminución general en las tasas de anécdotas publicadas durante este tiempo.Aquellas publicadas cubrían un amplio rango de temas y taxones, pero estaban sesgadas hacia primates diurnos, más grandes -en particular, simios. Sugerimos que la evidencia anecdótica debe continuar siendo publicada, pero que la publicación de estos datos debe reflejar mejor la diversidad taxonómica de los primates. También sugerimos lugares potenciales para la publicación de anécdotas que pueden compensar por su pérdida de las revistas académicas formales. [narrativas, datos cualitativos, antropomórfico, primates, observación] RÉSUMÉ Des descriptions narratives formelles ont longtempsété utilisées par les primatologues pour décrire des phénomènes nouveaux observés. Toutefois, une transition vers l'utilisation de méthodes quantitatives plutôt que de comptes-rendus narratifs a progressivementété observée en primatologie. L'objectif de cette recherché etait d'examiner cette transition en faisant une revue systématique des comptes-rendus anecdotiques publiés dans
