Cercocebus agilis has a steady population and is not considered in current danger of extinction. However, deforestation is a potential threat to those populations not living in protected areas, and the Association of Zoos and Aquariums has set up a Species Survival Plan for them. These animals are also occasionally killed for their meat and as pests.
US Federal List: no special status
CITES: appendix ii
IUCN Red List of Threatened Species: least concern
Non-human predation on agile mangabeys is relatively low because of the environments in which these monkeys typically live. Terrestrial predators can not easily hunt in swampy or flooded areas, and predatory birds can not easily pick off animals living in dense undergrowth. However, leopards (Panthera pardus), pythons (Python), and crowned eagles (Stephanoaetus coronatus) are all known to feed on agile mangabeys to some extent. Agile mangabeys are also hunted by humans as a sources of bush meat.
Anti-predator adaptations of this species, aside from its difficult environment, include alarm-calling. The particular alarm call of the agile mangabey is a long-series, high-frequency "chuckle."
Known Predators:
Except for the tail region, the pelage of agile mangabeys is brownish-gray agouti that becomes darker on the back; the tail is agouti only at the base of the fur. The tips of the fur are generally black on the dorsal side of the body. The entire underside is a lighter fawn color. Hair on the head radiates out from a whorl just above the forehead. The bare skin of the hands and feet is black. Except for the upper eyelids, the skin of the ears and face is also black with a border of lighter skin at the hair line. The facial skin of infants begins light but darkens as they age. Color morphs of both light and dark variety reportedly co-occur with the typical color pattern. The size of this species varies somewhat, with western populations being slightly larger than eastern ones. All individuals have relatively long non-prehensile tails. Sexual dimorphism is significant, with adult females attaining only 60 percent of the mass of adult males.
The skull of agile mangabeys, like those of other members of genus Cercocebus, is exceptionally broad. Unlike other members of the subfamily Cercopithecinae, the upper molars of Cercocebus species are wider than they are long. The genus also possesses a "molar flare," which is shared with the rest of Cercopithecinae (other than guenons), as well as a long auditory meatus, wide interorbital pillar, and convex nasal bone. However, agile mangabeys have shorter and narrower skulls and smaller teeth than other Cercocebus species.
Range mass: 5 to 13 kg.
Range length: 44 to 65 cm.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: male larger
Agile mangabeys live for as long as 20 years in the wild, but average lifespan is unknown. Few agile mangabeys are kept in captivity, so their lifespan in captivity is also unknown.
Range lifespan
Status: wild: 20 (high) years.
Agile mangabeys live primarily in periodically flooded primary forests near bodies of fresh water. However, some populations in southern portions of the Central African Republic reportedly live in non-flooded mixed forests away from bodies of water. Agile mangabeys favor the understory and are generally terrestrial while feeding or traveling.
Habitat Regions: tropical ; terrestrial
Terrestrial Biomes: rainforest
Wetlands: swamp
Other Habitat Features: riparian
Agile mangabeys, Cercocebus agilis, are found only in forested regions of central Africa that lie north of the Congo river. Currently, this species is found in southeastern Cameroon, eastern portions of continental Equatorial Guinea, northeastern Gabon, northern parts of the Republic of the Congo, southern and central parts of the Central African Republic, and northern parts of the Democratic Republic of the Congo.
Biogeographic Regions: ethiopian (Native )
Agile mangabeys are generalized omnivores that feed on plant, fungi, and animal material. They prefer both ripe and unripe fruits and, particularly, old hard nuts and seeds that they open with their robust molars and thickened enamel. These nuts may be found on the ground or buried beneath and even in elephant dung that the monkeys go through. Furthermore, agile mangabeys have large incisors and particularly strong jaw muscles that can be used to crack open fruits and pods too tough for other sympatric species of monkeys. Besides fruit, nuts, and seeds, agile mangabeys consume leaves, monocotyledon hoots, the terminal tips of herbs and grasses, roots, fungi, buds, bird eggs, insects, and occasional vertebrates. Animal matter represents a significant part of their diet. Agile mangabeys are reported to spend 26 to 30 percent of their feeding foraging only for insects and have been known to kill vertebrates as large as young antelope. Like all "cheek pouch" monkeys, agile mangabeys are capable of gathering food into pouches in their cheeks to be saved for consumption later on.
Animal Foods: mammals; eggs; insects
Plant Foods: leaves; roots and tubers; seeds, grains, and nuts; fruit
Other Foods: fungus
Primary Diet: omnivore
The primary role that Cercocebus agilis likely plays in its environment is that of seed disperser. Since agile mangabeys specialize in breaking open and eating particularly tough fruits, seed pods, and nuts (many of which may remain on the forest floor for years before being eaten), it is likely that these monkeys play some role in the reproduction of the species of plants to which the fruits, nuts, and seed pods belong. They almost certainly affect the populations of the insects that they eat, since these make up a significant portion of their diet, and they probably have some small affect on small vertebrate populations within their home ranges. Agile mangabeys are also prey for larger predators.
Agile mangabeys serve as hosts for a variety of parasitic species. In a study published in 2002 and conducted on a variety of humans and non-human primates living in a park in the Central African Republic, agile mangabeys were found to host at least 7 different kinds of parasites, including ascaroid and strongylate helminths, trichomonads,and various protozoa.
Ecosystem Impact: disperses seeds
Commensal/Parasitic Species:
Agile mangabeys are sometimes hunted for bushmeat.
Positive Impacts: food
Agile mangabeys are likely carriers of some human diseases or, at least, or strains closely related to human versions of the same disease. These include T-cell leukemia virus and probably Simian Immunodeficiency Virus as well. Since agile mangabeys are hunted for bushmeat, the potential for mutated strains of these viruses to jump hosts and spread to human populations is greatly increased. This species is also viewed by locals in the areas where it lives as a crop pest.
Negative Impacts: injures humans (carries human disease); crop pest
Agile mangabeys communicate primarily through visual and auditory signals, but they may also use olfactory and tactile signals as well. Vocal communication is particularly important in a forested environment when danger calls emitted by one member of a group can alert the rest to the presence of a predator or communicate the group's position to other neighboring groups. Visual communication is typically used in interactions between members of the same group. Aggression, for example, is displayed through a combination of staring, raising the eyebrows, flashing the eyelids, bobbing the head, and opening the mouth while the teeth remain covered by the lips. Sexual readiness is indicated through "pouting." Olfactory communication is limited to pheromone production. Males, for instance, can check a female's estrous status by sniffing her when she presents to him. Tactile communication is limited primarily to instances in which one individual mounts another for non-sexual reasons; presenting for non-sexual reasons is linked to the pacification of dominant individuals by subordinate individuals. Like all primates, they perceive the world around them using smell, touch, taste, hearing, and, especially, vision.
Communication Channels: visual ; tactile ; acoustic ; chemical
Other Communication Modes: pheromones
Perception Channels: visual ; tactile ; acoustic ; chemical
Agile mangabeys live in small to medium-sized groups of animals that may include either one or several males. Females develop sexual swellings when they are in estrous. It is assumed that they are either polygynous or promiscuous, but not much is known about their mating behavior in the wild.
Mating System: polygynous ; polygynandrous (promiscuous)
Agile mangabeys begin breeding at age 4 to 5 and breed throughout the year with a gestation period of 165 to 175 days. They have only one offspring at a time. Newborn offspring are mostly hairless and cling to the underbelly fur of their mothers while the mothers move around.
Breeding interval: The breeding interval for agile mangabeys is not known.
Breeding season: Agile mangabeys breed year round.
Average number of offspring: 1.
Range gestation period: 165 to 175 days.
Range age at sexual or reproductive maturity (female): 4 to 5 years.
Range age at sexual or reproductive maturity (male): 4 to 5 years.
Key Reproductive Features: iteroparous ; year-round breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous
Parental care is provided primarily by the mother in the form of nursing and carrying infants. However, males sometimes hold and carry infants. It is not known whether or not this behavior correlates with paternity. Upon reaching independence, the young group with others of the same age and generally avoid adults.
Parental Investment: altricial ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Male, Female); extended period of juvenile learning

Die Olivmangabe (Cercocebus agilis) ist eine Primatenart aus der Familie der Meerkatzenverwandten (Cercopithecidae).
Olivmangaben erreichen eine Kopf-Rumpf-Länge von rund 45 bis 65 Zentimeter, wozu noch ein ungefähr gleich langer Schwanz kommt, sie wiegen 5 bis 13 Kilogramm, wobei die Männchen deutlich größer als die Weibchen werden. Ihr Fell ist an der Oberseite graugrün oder olivgrün gefärbt, der Bauch ist heller, oft weißlich.
Olivmangaben leben im mittleren Afrika. Ihr Verbreitungsgebiet reicht von Kamerun und Äquatorialguinea über den Norden von Gabun und der Republik Kongo bis in die nördliche Demokratische Republik Kongo. Hier bildet der Kongo-Fluss die Südgrenze ihres Habitats, südlich davon lebt die verwandte Goldbauchmangabe. Ihr Lebensraum sind Wälder in der Nähe von Flüssen oder Seen, die zumindest zeitweise überflutet sind.
Vermutlich stellt die Zerstörung des Lebensraums eine Gefährdung für die Art dar. Die IUCN listet die Art jedoch als „nicht gefährdet“ (least concern).[1]
Sie sind wie alle Altweltaffen tagaktiv und halten sich zeitweise am Boden auf, die Männchen mehr als die Weibchen. Sie leben in Gruppen von etwa 8 bis 18 Tieren zusammen, die sich aus einem oder mehreren Männchen, etlichen Weibchen sowie den dazugehörigen Nachwuchs zusammensetzen.
Die Männchen führen und beschützen die Gruppe. Sie stoßen laute Schreie aus, die sowohl die Gruppe zusammenhalten als auch andere Gruppe auf die eigene Anwesenheit aufmerksam machen.
Olivmangaben sind Allesfresser, die jedoch vorzugsweise Früchte zu sich nehmen. Daneben verzehren sie auch Samen, Nüsse, Knospen und Pilze, aber auch Vogeleier sowie Insekten und andere Kleintiere.
Früher galt die Olivmangabe als Unterart der Haubenmangabe (als Cercocebus galeritus agilis), erst seit den 1970er-Jahren wird sie als eigenständig betrachtet. Die Goldbauchmangabe wiederum galt als Unterart der Olivmangabe und wird seit 2001 als eigene Art geführt.
Die Olivmangabe (Cercocebus agilis) ist eine Primatenart aus der Familie der Meerkatzenverwandten (Cercopithecidae).

The agile mangabey (Cercocebus agilis) is an Old World monkey of the white-eyelid mangabey group found in swampy forests of Central Africa in Equatorial Guinea, Cameroon, Gabon, Central African Republic, Republic of Congo, and DR Congo.[1] Until 1978, it was considered a subspecies of the Tana River mangabey (C. galeritus).[3] More recently, the golden-bellied mangabey (C. chrysogaster) has been considered a separate species instead of a subspecies of the agile mangabey.[1]
The agile mangabey has a short, overall dull olive-grey pelage.[4] The bare skin of the face and feet is blackish.[5] Males are 51–65 centimeters (20–26 inches) in length and weigh about 7–13 kilograms (15–29 lb), while the smaller females are 44–55 centimeters (17–22 inches) and weigh 5–7 kilograms (11–15 lb).[4]
Similar to other mangabeys, they are diurnal.[3] Although generally arboreal, they do spend a significant portion of their time (12–22%) on the ground,[5] especially during the dry season. It is typically more commonly heard than seen,[4] and males have a loud, species-specific call that is believed to be used to space themselves out.[3] Other calls are also used to maintain group cohesion and warn of predators.[5] Group size can be as high as 18 members, led by a single adult male. Group meetings can be friendly and may involve exchange of members. Adult males not in groups often travel singly.[4]
Fruit makes up a major portion of the agile mangabey diet. They are known to eat at least 42 different species of fruit.[5] Their tooth structure and powerful jaws allows them to open tough pods and fruits that many other monkeys can not access.[5] Agile mangabeys eat from a number of dominant swamp-forest trees, including dika nuts and sugar plums, when they are fruiting.[4] They also eat fresh leaf shoots from raffia palms when fruits are scarce. Grasses and mushrooms,[4] as well as insects, other invertebrates, bird's eggs and some vertebrate prey, such as rodents, are also eaten.[5]
Agile mangabeys are known to contract T-cell leukemia virus, similar to the leukemia virus that infects humans.[6] There is also evidence that they contract Simian immunodeficiency virus (SIV), a virus related to human HIV that infects certain apes and monkeys.[7] They have rarely been kept in captivity,[5] with only three individuals held in Species360 registered institutions in July 2008.[8]

El mangabeye ágil (Cercocebus agilis) es una especie de primate catarrino perteneciente a la familia Cercopithecidae que habita en los bosques pantanosos de África Central en Guinea Ecuatorial, Camerún, Gabón, República Centroafricana, República del Congo y la República Democrática del Congo.[2] Hasta 1978, se le consideró una subespecie del mangabeye del río Tana.[3] Más recientemente, el mangabeye de vientre dorado se consideró una especie en lugar de una subespecie del mangabeye ágil.[2]
El mangabeye ágil tiene un pelaje corto de color oliva pálido a gris.[4] La piel desnuda de la cara y los pies es negruzca.[5] Los machos miden entre 51 y 65 centímetros de longitud y un peso de 7 a 13 kilogramos, mientras que las hembras, más pequeñas, miden de 44 a 55 centímetros y un peso de 5 a 7 kilogramos.[4]
Al igual que los demás mangabeyes, son animales diurnos.[3] A pesar de ser predominantemente arbóreos, pasan una parte sustancial del tiempo (12–22%) en el suelo,[5] especialmente durante la estación seca. Son escuchados con más frecuencia que lo que son avistados,[4] y los machos emiten un llamado fuerte, específico para la especie el cual se cree utilizan para mantener la distancia.[3] Otros llamados son usados también para mantener la cohesión del grupo y evitar los depredadores.[5] Pueden formar grupos de hasta 18 miembros, liderados por un macho adulto. Los encuentros de los grupos suelen ser amigables e incluye intercambio de miembros. Los machos adultos no suelen hacer parte de grupos y a menudo viajan por separado.[4]
Las frutas constituyen la mayor parte de la dieta del mangabeye ágil. Se sabe que consumen por lo menos 42 especies diferentes de frutas.[5] Su dentadura y mandíbulas poderosas le permiten abrir vainas duras y frutas que otros monos no pueden comer.[5] También comen brotes tiernos de rafia cuando las frutas escacean, hierbas y setas,[4] e insectos, otros invertebrados, huevos de aves y algunos vertebrados pequeños como roedores.[5]
Al mangabeye ágil se le conoce por contraer el virus de la leucemia de células T, similar al que afecta a los humanos.[6] También existe evidencia que adquieren el virus de inmunodeficiencia simiana (VIS), relacionado con el VIH humano, que afecta a algunos primates.[7] Son raros en cautiverio con solo tres individuos registrados para 2008.[8]

Il cercocebo agile (Cercocebus agilis) è una scimmia del Vecchio Mondo, appartenente alla famiglia Cercopithecidae.
La lunghezza del corpo varia tra 45 e 65 cm, quella della coda è approssimativamente la stessa. Il peso può variare tra 5 e 13 kg: il maschio, che può pesare tra 7 e 13 kg, è notevolmente più grande della femmina, il cui peso varia tra 5 e 7 kg. Il colore è olivastro o grigio-verde sul lato dorsale, mentre il lato ventrale è più chiaro, spesso biancastro. Il muso e le estremità degli arti sono neri.
L'areale è in Africa centrale, dal Camerun alla Guinea equatoriale al Gabon settentrionale alla Repubblica del Congo alla Repubblica Democratica del Congo settentrionale ed è limitato a sud dal fiume Congo, al di là del quale vive la specie affine Cercocebus chrysogaster. L'habitat è la foresta pluviale tropicale e in particolare le zone prossime all'acqua che sono inondate stagionalmente.
Come le specie affini, hanno attività diurna sia arboricola che al suolo. La dieta, oltre a frutta e vari altri alimenti vegetali, include uova, insetti e altri piccoli animali. Recentemente, è stato appurato che questa particolare specie di scimmia ha acquisito da non troppo tempo una nuova abitudine, ovvero quella di cibarsi di piccole antilopi, in genere cuccioli.[2]
Formano gruppi territoriali con uno o più maschi adulti, che possono contenere da 8 a 18 individui.

Mangabei-ágil (Cercocebus agilis) é um macaco do Velho Mundo encontrado nas florestas pantanosas da África Central, na Guiné Equatorial, Camarões, Gabão, República Centro-Africana, Congo e República Democrática do Congo.[2] Até 1978, era considerado uma subespécie de Cercocebus galeritus.[3] Mas recentemente, Cercocebus chrysogaster tem sido considerado uma espécie separada de C. agilis, em vez de uma subespécie.[2]
C agilis possui a pelagem de cor cinza-oliva escuro.[4] A face sem pelos e os pés, são pretos.[5] Machos possuem entre 51 e 60 cm de comprimento e pesam entre 7 e 13 kg, enquanto as fêmeas pesam entre 5 e 7 kg e possuem entre 44 e 55 cm de comprimento.[4]
Como os outros macacos do gênero Cercocebus, são diurnos.[3] Embora sejam geralmente arborícolas, passam uma porção significativa do tempo no chão (entre 12 e 22%), especialmente na estação seca.[5] é mais fácil ouvi-los do que vê-los,[4] e os machos possuem vocalizações poderosas, que provavelmente servem na demarcação de território.[3] Outras vocalizações são emitidas para manter a coesão do grupo e alarmar contra predadores.[5] O tamanho do grupo pode ser de até 18 membros, com apenas um macho. Os encontros entre os grupos são amigáveis e podem envolver trocas de membros. Machos adultos sem grupo geralmente se deslocam sozinho.[4]
Frutos forma a maior parte da dieta de C. agilis. Eles são conhecidos por comer pelo menos 42 espécies diferentes.[5] A estrutura dos dentes e suas mandíbulas permitem abrir cascas duras que muitos macacos não conseguem ter acesso.[5]

Cercocebus agilis[2][3][4] är en däggdjursart som beskrevs av Milne-Edwards 1886. Cercocebus agilis ingår i släktet Cercocebus och familjen markattartade apor.[5][6] IUCN kategoriserar arten globalt som livskraftig.[1] Inga underarter finns listade.[5]
Cercocebus agilis är en smal primat med långa extremiteter och lång svans. Honor är med en kroppslängd (huvud och bål) av 44 till 55 cm och en vikt av 5 till 7 kg mindre än hanar. De senare blir 51 till 65 cm lång (huvud och bål) och 7 till 13 kg tung. Svanslängden är för båda kön 45 till 79 cm. Pälsen på ovansidan har en brungrå till olivgrå färg och undersidan är ljusare, ibland vitaktig. Ansiktet, öronen samt händer och fötter är bara glest täckt med hår och svartaktiga.[7]
Denna primat förekommer i centrala Afrika från Kamerun och Gabon i väst till Albertsjön i öst. Habitatet utgörs främst av skogar i träskmarker samt av andra skogar.[1]
Hannar och honor bildar flockar med 8 till 22 medlemmar och ibland ingår individer av arten Lophocebus albigena i gruppen. Reviret är cirka 300 hektar stort. Födan utgörs av frukter, frön och unga växtskott.[1] Dessutom äter arten svampar, insekter och andra ryggradslösa djur samt fågelägg.
Individerna är aktiva på dagen och klättrar främst i växtligheten. Flocken bildas av en vuxen hane, flera honor och deras ungar. För kommunikationen har de olika läten samt varierande ansiktsuttryck och kroppsställningar. När den dominerande hanen förlorar sin status dödar den nya alfahanen ibland flockens nyfödda ungar. För arten finns ingen särskild parningstid. När en hona är parningsberedd blir regionen kring hennes könsorgan och anus tjockare. Dräktigheten varar cirka 6 månader och sedan föds allmänt en unge.[7][8]

Країни проживання: Камерун; Конго; Демократична Республіка Конго; Екваторіальна Гвінея; Габон. Цей вид зазвичай зустрічається в періодично затопленому болотному лісі.
Вони денні й хоча в цілому деревні, проводять значну частину свого часу (12-22%) на землі, особливо під час сухого сезону. Вони живуть разом у групах від 8 до 18 тварин, які складаються з одного або кількох самців, кількох самиць і потомства. Самці володіють гучним голосом. Це всеїдні тварини, переважно їдять плоди. Крім того, вони також їдять насіння, горіхи, шишки і гриби, а також пташині яйця і комах та інших дрібних тварин. Відомі хижаки: Panthera pardus, Stephanoaetus coronatus, Python, Homo sapiens.
Цей вид знаходиться під загрозою втрати середовища проживання, викликаного збезлісенням. На нього також локально полюють на м'ясо і тварин переслідують за рейдерство. Цей вид занесений до Додатка II СІТЕС і класу B Африканської Конвенції про збереження природи і природних ресурсів. Як передбачається, живе в ряді ПОТ.

Cercocebus agilis (Milne-Edwards, 1886)
Ареал
Прыткий мангабей[1] (лат. Cercocebus agilis) — вид обезьян семейства мартышковых отряда приматов, один из видов рода Мангабеи. Представители этого вида встречаются в центральной Африке в Центрально-Африканской Республике, Экваториальной Гвинее, Камеруне, Габоне, Республике Конго и Демократической Республике Конго. До 1978 года считался подвидом танского мангабея (C. galeritus).[2] Помимо этого недавно золотобрюхий мангабей (C. chrysogaster), ранее входивший в ранге подвида в состав вида Cercocebus agilis, был поднят до ранга вида.
Шерсть короткая, оливково-серая.[3] Лицо, ступни и ладони безволосые, с чёрной кожей.[4] Длина тела самцов от 51 до 65 см, вес от 7 до 13 кг. Длина тела самок от 44 до 55 см, вес от 5 до 7 кг.[3] Существуют свидетельства того, что прыткие мангабеи могут быть заражены вирусом иммунодефицита обезьян.[5]
Активны днём. Ведут в основном древесный образ жизни, однако значительную часть времени (12—22 %) проводят на земле,[4] особенно во время сухого сезона. У самцов громкий крик, отличающий этот вид от родственных видов.[2] Образуют группы размером до 18 особей. Во главе каждой группы доминантный самец. Случаи агрессии между группами редки, часто при встрече различных групп происходит обмен членами.[3]
В рационе в основном фрукты, зафиксировано потребление по меньшей мере 42 различных видов фруктов.[4] Строение челюстей позволяет прокусывать кожуру твёрдых фруктов, недоступных другим видам обезьян.[4] Дополнением к рациону служат орехи, молодые листья и трава, грибы, насекомые и прочие беспозвоночные, птичьи яйца и мелкие млекопитающие.[4]

Представители этого вида встречаются в центральной Африке в Центрально-Африканской Республике, Экваториальной Гвинее, Камеруне, Габоне, Республике Конго и Демократической Республике Конго. До 1978 года считался подвидом танского мангабея (C. galeritus).
