The Djaffa Mountains guereza (Colobus guereza gallarum) is an endemic Ethiopian taxon. Information about its distribution and population size is missing. We collected data on population density and size in four forests in the Ahmar Mountains in a line-transect survey and estimated 109.6 individuals per square kilometer within the study area. This comparatively high density is thus not the main conservation concern, but the fragmentation of the guereza habitat and population is.

From November 2011 through to November 2019, we carried out seasonal road transect surveys and estimated population densities of Manyara monkeys and vervet monkeys in Lake Manyara National Park. Both species occurred at relatively high densities, and their population trends remained fairly stable over the study period. Our research highlights the value of long-term monitoring and the importance of Lake Manyara National Park as a stronghold for the endemic and endangered Manyara monkey.

The Manyara monkey was described as a new subspecies of the Cercopithecus mitis species complex in 2020. We sequenced a part of its mitochondrial genome and reconstructed the phylogeny of the mitochondrial lineages. The reconstruction suggests that the Manyara monkey clusters in the youngest of three major C. mitis clades. Our data support the phylogeographic hypothesis of a west-east range expansion of gentle monkeys into eastern and southern Africa.

Baboons occur in a large range of different habitats. However, data on the ecology of Guinea baboons were scarce. We provide information on the ranging behaviour, habitat use, and diet of a population of Guinea baboons in the Niokolo-Koba National Park, Senegal. Home ranges were about 25 km2, and they moved up to 13 km per day. They seem to prefer the more forested parts of their home range near the river. Fruit dominates their diet, and the nuts of the palmyra palm are a year-round food source.

Ethiopia is well-known for its high biodiversity and endemism. Among these endemics are two putative subspecies of the guereza: Colobus guereza guereza and C. g. gallarum. Our molecular study supports the two-subspecies hypothesis, making C. g. gallarum an Ethiopian endemic taxon. In combination with its very restricted range, C. g. gallarum is most likely one of the most endangered subspecies of black-and-white colobus.

Reports of male dominance in greater bamboo lemurs were not supported by data. We studied agonistic behavior in one captive group and could confirm this assertion, which sets this species apart from all other group-living lemurs.

A camera trap captured the moment in which a group of collared peccaries attacked and killed a howler monkey at a clay lick in the Taricaya Ecological Reserve, Madre de Dios, Peru. This novel behaviour helps us understand the myriad risks howler monkeys face when descending to the forest floor while also indirectly emphasizing the importance of geophagy for these animals.

As part of our study on coppery titi monkeys in the Peruvian Amazon, we observed an individual rubbing his belly with leaves from a potentially medicinal plant. He climbed down from high above and grabbed a handful of leaves from an understory tree, which made it look like a deliberate action. Sitting on a liana he then chewed on the leaves before rubbing them slowly on his belly for a couple of minutes. The plant genus is known in traditional medicine and is used for various effects.

We report the first masturbatory behaviour in a male Phayre's langur, in a semi-evergreen forest in Bangladesh. We discuss possible reasons for masturbation and suggest an adequate characterization of the socio-sexual behaviour and reproductive strategies of this globally endangered primate to demonstrate the causes, cost and consequences of masturbation. We also urge further scientific exploration into masturbation among primates due to its evolutionary and conservation significance.

We examined the influence of forest edge effects on activity budgets, feeding ecology, and stress hormone output in five groups of Verreaux’s sifakas (Propithecus verreauxi) in western Madagascar. Sifakas in the edge habitat travelled more, tended to have smaller home ranges, had lower fruit consumption, higher stress hormone levels, and lower birth rates than sifakas in the forest interior. Hence, Verreaux’s sifakas appear to be sensitive to microhabitat characteristics linked to forest edges.

Sleep is the longest and most continuous behavioral phase in the 24 h cycle of mammals. However, selection of postures, substrates, and tree parts during sleep has not been adequately explored, as well as their evolutionary consequences. The present study investigates postural behavior, substrate, and tree part use during sleep in three howler species (A. palliata, A. macconnelli, and A. caraya) in Nicaragua, French Guiana, and Argentina. All three species were consistent in the use of a crouch.

Reactions to predators vary a lot in primates and can be passive (hiding, fleeing) or active (mobbing, alarm calls). Due to their secretive lifestyle, Neotropical titi monkeys are thought to use mainly passive crypsis and hiding as anti-predator responses. Predator mobbing has been reported only for one titi species, Callicebus nigrifrons. We report mobbing of an ocelot and Boa constrictor in red titi monkeys and Plecturocebus cupreus, and alarm calling as a reaction to tayras and raptors.

These data come from the major study on gut passage with two primate species (Callicebus coimbrai and Callicebus barbarabrownae) enclosed in the Zoobotanical Park localized in the north-eastern Brazil. During the sampling period, we have decided to obtain self-anointing and laterality data. Due to the presence of large glands in C. coimbrai and C. barbarabrownae chests, we cautiously suggest that the use of Bauhinia may be linked to olfactory communication.

We report observations fur-rubbing with leaves from the spiked pepper plant, Piper aduncum, in the San Martín titi monkey, Callicebus oenanthe. As leaf extracts from this plant include insecticidal compounds, we interpret this behaviour as a defense against ectoparasites. Our observations expand the number of primate species for which this kind of self-medication is reported.

Coalitions are a specific case of cooperative competition and have been explained by various factors like partner availability, distribution of fighting ability, or cost of coordination. We investigated if age is an important factor influencing coalition formation and, specifically, if males switch from a solo strategy to a cooperative one after reaching post-prime age. We found that older males formed more coalitions than younger ones, stressing the importance of age in cooperative competition.

We report on extremely rare events of group eviction and eventually lethal aggression in a group of ring-tailed lemurs (Lemur catta) that were targeted against the two highest-ranking females. These events erupted after an infanticide by the highest-ranking female directed at the offspring of a subordinate. We suggest that this aggressive changeover of power between two matrilines was based on the growing group size and was an act of female reproductive competition during birth season.

We describe the acquisition, sharing and consumption of meat by wild Guinea baboons. Males were the hunters and shared meat passively only with females in their social and reproductive units. Females were able to acquire meat from sharing episodes and by scavenging from their male social partners. The presence of existing social bonds, rather than short-term exchanges of meat for sex, is likely a driving factor in the occurrence of meat sharing between males and females in this species.

Terrestrial drinking is not normally reported for arboreal primates. Here we report observations of terrestrial drinking from man-made watering holes by Temminck’s red colobus (Piliocolobus badius temminckii) at two sites in The Gambia. Our observations show that shallow man-made watering holes, not harbouring predators, were used by different age classes. The implications of this behaviour for this endangered subspecies and the trend of increasing temperatures in The Gambia are discussed.

We report the first case of putative empathic response in titi monkeys (Callibebus). Pair bonds between males and females are typically strong, with substantial time spent grooming and tail twining. In an intriguing and unexpected observation we recorded an injured adult out-group male travelling with a neighbouring group. The group appeared to adapt travel patterns to allow him to accompany them, provided pro-social behaviour such as grooming and tolerated his presence at their sleeping site

Short summary
Here we report two encounters between olive baboons (Papio anubis) and crowned eagles (Stephanoaetus coronatus), a potential predator, at Lake Manyara National Park, Tanzania. On both events, baboons gave alarm calls while infants got close to adults and juveniles ran to cover. Adult males approached the eagles and chased them away. The baboons’ reactions indeed support the assumption that crowned eagles pose a threat, at least for juvenile baboons.
