These monkeys probably have some impact on their ecosystem. As a potential prey species, the abundance of these monkeys may affect the abundance of predators. In addition, their reliance on leafy vegetations, fruits and seeds, may affect the plant community, especially by dispersing seeds.
Ecosystem Impact: disperses seeds
Predators of these colobus monkeys are not reported. However, because of the size of these monkeys and their arboreal habits, likely predators include raptors and leopards. Large snakes might also take young animals.
Males, on average, weigh approximately 9.90 kg, whereas a typical female is near 8.30 kg. Head and body length range from 450 to 720 mm, tail length from 520 to 1,000 mm. Colobus polykomos has white markings like most other species within the genus Colobus, however, this species is distinctive in that the chest and whiskers are white while the rest of the body is black. Further, the tail is entirely white and not tufted (Nowak, 1999). Colobus polykomos is slender- bodied with a long tail and prominant rump callosities. A complex sacculated stomach is present, but cheek pouches are absent. The thumb is reduced to a mere tubercle, the skull is somewhat prognathous, and the orbits are oval with narrow superciliary ridges (Nowak, 1999). The nostrils are lengthened by an extension of the nasal skin and may extend to nearly the mouth.
Range mass: 5 to 14 kg.
Range length: 450 to 720 mm.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: male larger
The maximum longevity reported for this species is 23.5 years in captivity. Wild life spans are not known with certainty, but are likely to be lower than this.

Most African forests in which C. polykomos is found experience prolonged and pronounced dry seasons. Most of the forest lies within 10 degrees of the equator and is characterized by two rainfall peaks interspersed with two relatively dry periods--one short and one long. Much of the African moist forest zone is dominated by a single leguminous tree species. At present, much of C. polykomos habitat has been overrun by farming (especially rice cultivation) and tree cutting. This being the case, these areas typically support a variable array of young secondary forest. The old secondary forest (60% of the habitat) is dominated by the leguminous trees.
Habitat Regions: tropical ; terrestrial
Terrestrial Biomes: forest ; rainforest ; scrub forest
Individuals of the genus Colobus are typically found in tropical rain forests (lowland and montane types) of Africa, in the countries of Senegal, Ethiopia, Tanzania, Congo, Malawi, Uganda and Zambia. Colobus polykomos is limited to a range from Gambia to the Ivory Coast.
Biogeographic Regions: ethiopian (Native )
Although C. polykomos is generally highly arboreal, members of this species are found to feed on the ground. Colobus groups typically have a daily foraging path of only about 500 meters. The diet consists mostly of leaves, but fruits and flowers can be more/less important depending upon the season (Nowak, 1999).
Plant Foods: leaves; seeds, grains, and nuts; fruit; flowers
Primary Diet: herbivore (Folivore )
In the nineteenth century, C. polykomos was hunted by humans extensively for use of its fur . More recently, however, C. polykomos has provided little economic benefit for humans. They could be considered important in ways other than economically, however, due to the fact that they are ecologically, anatomically and socially interesting.
Their numbers are so low as to have little to no effect on humans whatsoever.
Colobus polykomos is considered to be highly endangered because of habitat destruction and hunting. Habitat destruction occurs through subsistance farming, commercial agricultural development and selective logging. Colobus polykomos is also extremely vulnerable to hunting by humans, both for their meat and fur.
Attempts at maintaining this species in captivity has largely failed, most probably because of their digestive peculiarities. Instead, it is important to manage C. polykomos habitat forests effectively and prevent any further habitat destruction in order to protect and conserve them.
CITES: appendix ii
IUCN Red List of Threatened Species: vulnerable
Communication in most primates is complex, involving visual signals (such as facial expressions and body postures), vocalizations, and different forms of physical contact ( such reassurance gestures, aggression, grooming). It is likely that these monkeys employ all means of communication listed above.
Communication Channels: visual ; tactile ; acoustic
Perception Channels: visual ; tactile ; acoustic ; chemical
The mating system has been described as 'unimale'--one male mating with several females, as well as 'multimale' where multiple males mate with multiple females.
Mating System: polygynous ; polygynandrous (promiscuous)
There is conflicting evidence regarding seasonality of reproduction. In some groups, C. polykomos has been observed to give birth year round, but in others the birth season coincides with the dry season (December-May). This is thought to occur as a result of the greater availability of fruit as well as access to crops and human provisioning.
The gestation period of this species is 175 days on average, and the interbirth interval is approximately 24 months. Females, on average, produce 1 offspring every 20 months (Nowak, 1999) and reach sexual maturity at approximately 2 years of age.
Breeding interval: Colobus polykomos breed once every two years.
Breeding season: Data on breeding seasonality is somewhat conflicting, with some populations breeding year round, and others breeding so that births occur during the rainy season.
Average number of offspring: 1.
Average gestation period: 175 days.
Average age at sexual or reproductive maturity (female): 2 years.
Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous

Der Weißbart- oder Bären-Stummelaffe (Colobus polykomos) ist eine Primatenart aus der Gruppe der Stummelaffen (Colobini).
Weißbart-Stummelaffen sind wie alle Stummelaffen schlanke, langschwänzige Primaten mit rückgebildetem Daumen. Das Fell ist überwiegend schwarz gefärbt, lediglich die Backenhaare und die Brust sind weiß. Der Schwanz ist ebenfalls gänzlich weiß und hat im Gegensatz zu anderen Vertretern der Schwarz-weißen Stummelaffen keine Quaste.
Weißbart-Stummelaffen sind im westlichen Afrika beheimatet, ihr Verbreitungsgebiet erstreckt sich von Gambia bis zur Elfenbeinküste. Ihr Lebensraum sind Wälder.
Diese Primaten sind tagaktive Baumbewohner, die sich meist im Kronendach aufhalten und selten auf den Boden kommen. Sie leben in kleinen Gruppen, die sich aus einem Männchen (manchmal auch mehr), etwa drei bis vier Weibchen und dem gemeinsamen Nachwuchs zusammensetzen. Es sind territoriale Tiere, zwar überlappen sich die Reviere zum Teil, einzelne Gruppen gehen einander aber aus dem Weg. Lautes Brüllen der Männchen am Morgen weist die anderen Gruppen auf den Aufenthaltsort hin. Begegnen sich zwei Gruppen dennoch, kommt es zwischen den jeweiligen Männchen zu aggressivem Verhalten, das mit Gesten, lautem Brüllen und auch mit körperlichen Auseinandersetzungen ausgetragen wird.
Weißbart-Stummelaffen nehmen vorwiegend Blätter zu sich, daneben fressen sie auch Früchte und Samen. Ein mehrkammeriger Magen hilft ihnen bei der Verwertung der schwer verdaulichen Blätternahrung.
Nach einer knapp sechsmonatigen Tragzeit bringt das Weibchen meist ein einzelnes Jungtier zur Welt. Dieses ist zunächst weiß gefärbt, und nicht nur die Mutter, sondern auch die anderen Weibchen der Gruppe kümmern sich darum.
Wie viele andere Bewohner der westafrikanischen Wälder leiden die Weißbart-Stummelaffen an der fortschreitenden Zerstörung und Verkleinerung ihres Lebensraums. Die IUCN listet die Art zwar als gering gefährdet, gibt aber an, dass diese Einschätzung veraltet ist.
Im Duisburger Zoo werden einige Tiere gehalten, der Zoo verwaltet auch das Zuchtbuch, in dem der Weltzoobestand gepflegt wird.[1]
Der Weißbart- oder Bären-Stummelaffe (Colobus polykomos) ist eine Primatenart aus der Gruppe der Stummelaffen (Colobini).
The king colobus (Colobus polykomos), also known as the western black-and-white colobus, is a species of Old World monkey, found in lowland and mountain rainforests in a region stretching from Senegal, through Guinea-Bissau, Guinea, Sierra Leone and Liberia to the Ivory Coast.[2] One of five members of the genus Colobus, the black-and-white colobuses, the king colobus is the westernmost species of the group on the continent of Africa.[3] It eats mainly leaves, but also fruits and flowers. Though it is arboreal, it eats primarily on the ground. It lives in small groups consisting of 3 to 4 females and 1 to 3 males, plus their young. These groups maintain distance from one another through territorial calling.[4]
The word 'Colobus' comes from the Greek word for 'mutilated', as all Colobus monkeys only have a short stump where the thumb would be. The word 'poly' comes from the Greek word for 'many.' The word 'komos' comes from the Greek celebration of unrestrained singing. A possible subspecies known as C. p. dollmani can be found but is most likely a hybrid with C. vellerosus.[2]
The male king colobus grows to a head-and-body length of 670 mm (26 in), with a tail of between 630 and 900 mm (25 and 35 in). The female is slightly smaller. Males weigh an average of 9.90 kg and females weigh an average of 8.30 kg.[4]
The body is black, the limbs and fingers are long and the tail is white. There is a fringe of silvery hair around the face as well as long white "epaulettes" on its shoulders.[5] The king colobus can be distinguished from other members of the Colobus genus by the placement of its white markings. The king colobus has white only on its whiskers, chest, and tail, and its tail is not covered by a tuft.[4]
The king colobus monkey is found in lowland and montane tropical rainforests.[2] The region in which they inhabit is limited to a small range on the Ivory Coast up to Gambia.[4] They can also be found in Senegal, through Guinea-Bissau, Guinea, Sierra Leone and Liberia.[2] Much of the habitat of the king colobus has been destroyed by humans for farming and secondary forests have begun to fill in this area. The forest habitats experiences significant dry seasons and two rainfall peaks. This area is dominated by leguminous trees.[4]
Diet consists mainly of arboreal leaves, but includes fruit and flowers depending on the season. It can be found foraging on the ground and typically stays within a foraging path of approximately 500 meters.[4]
It lives in small groups of less than 4 females and 1 to 3 males. Unlike males, females interact closely: males rarely interact and try to show dominance.[4] Either males or both sexes will disperse from family groups.[6][7][8]
The king colobus have an average home range of 22 hectares with some overlap between groups. Groups rarely encounter other groups of the same species but when they do, males engage in aggressive displays. Territorial calling is a common form of aggression but can also be a warning to the group of predators.[4]
King colobus have been shown to live approximately 23.5 years in captivity and possibly around 30 years in the wild.[4]
The king colobus live in a single male (polygynous) and multi-male (polygynandrous) mating system. Some groups have shown year round births while others have shown births in relation to the dry seasons. The average gestation period is 175 days and the females produce 1 offspring every 20 months. Both males and females reach sexual maturity at approximately 730 days or 2 years. Females provide the parental care by providing milk, grooming, protection and carry the newborns as they cannot walk immediately.[4]
The king colobus has a moderate-sized range; it used to be a common and widespread species but numbers have declined over the last few decades. The main cause for the decline is hunting which is threatening and fragmenting populations. In the 19th century the king colobus was hunted for its fur.[4] There is also a continuing decline in the quality and quantity of the forested habitat where it lives; it seems to be largely restricted to primary forest and gallery forest, although it sometimes visits secondary forest. The International Union for Conservation of Nature has rated its conservation status as being endangered.[2] Maintaining this species in captivity has mostly failed and focus has been on managing the habitats to prevent further degradation and habitat destruction that could harm the species.[4]

Colobus polykomos est une espèce qui fait partie des mammifères Primates. C’est un singe de la famille des Cercopithecidae, appelé, entre autres, Colobe à longs poils ou Colobe à camail. Ce colobe est une espèce vulnérable.
L'espèce est désignée en français par plusieurs noms vernaculaires : Colobe à longs poils, Colobe blanc-et-noir d'Afrique occidentale, Colobe d'Afrique de l'Ouest ou Colobe à camail[1]. On trouve aussi des appellations communes à d'autres espèces comme Colobe noir, Colobe magistrat[1] ou plus simplement « magistrat ».
C’est un singe d’une taille de 100 à 150 cm (queue comprise et comptant pour un peu plus de la moitié de la longueur), pour un ‘poids’ de 6 à 12 kg. Le pelage est relativement caractéristique : le corps et les membres sont noirs avec des traces de blanc, la queue entièrement blanche, et il a un bonnet de cheveux argentés, ébouriffés, et se terminant en longues épaulettes blanches. Son alimentation est semble-t-il très sélective : il consomme majoritairement une vingtaine d’espèces d'arbres et de lianes (feuilles et fruits).
Son aire de répartition est simple : il n’est présent que sur la côte ouest africaine de la Guinée Bissau à l’ouest de la Côte d’Ivoire. Elle est donc très petite. Ce singe habite dans les forêts pluvieuses et forêts galeries, si possible à proximité d’un cours d’eau. L'espèce est assez rare !

Il colobo orsino o colobo reale (Colobus polykomos Zimmermann, 1780) è un primate catarrino della famiglia dei cercopitecidi[1].
La specie vive nelle foreste pluviali di pianura e di montagna di una ristretta regione tra Gambia e Costa d'Avorio, in Africa.
Misura circa un metro e mezzo di lunghezza o poco più, di cui più della metà spetta alla lunga coda, per un peso medio di una decina di kg.
Il colobo orsino si distingue dagli altri membri del genere Colobus per la posizione delle zone bianche del pelame. L'intero corpo è nero, ad eccezione di baffi, petto e coda, che sono bianchi; inoltre quest'ultima non è dotata di ciuffi di pelo all'estremità.
Sulla testa il pelo cresce a guisa di cappello o di corona, sicché questo animale può sembrare un monarca (da cui il nome comune), così come un alto magistrato (ed è questo il suo nome in francese).
L'aspetto generale è quello di una scimmia di medie dimensioni, con corporatura slanciata, lunga coda e callosità ischiatiche ben evidenti. Lo stomaco ha struttura piuttosto complessa, simile a quello bovino: sono tuttavia assenti le sacche guanciali.
Il pollice è ridotto ad un misero mozzicone, mentre la faccia è prognata e dotata di pieghe cutanee che vanno dalle narici alla bocca.
Si tratta di animali sociali, che vivono in gruppi di una decina di individui, in cui le femmine sono presenti in numero leggermente superiore ai maschi. Queste ultime mantengono legami fra loro, pulendosi vicendevolmente, mentre i maschi raramente interagiscono fra loro e mostrano di possedere una chiara gerarchia.
CIascun gruppo occupa un territorio di estensione pari a circa 22 ettari: i vari gruppi mantengono le distanze l'uno dall'altro tramite richiami territoriali emessi dai maschi, che sono indicativi della consistenza numerica del gruppo e delle condizioni dei vari animali.
Si nutre soprattutto di foglie, ma anche di frutti e fiori: la percentuale di ciascun alimento ingerito varia a seconda della stagione.
Nonostante sia arboricolo, si nutre prevalentemente al suolo. Il nutrimento avviene in una porzione assai limitata di territorio, solitamente un percorso fisso di meno di mezzo chilometro.
A seconda della popolazione presa in esame, questi animali possono riprodursi per tutto l'arco dell'anno, oppure aspettare la stagione secca (dicembre-maggio) per farlo. Si pensa che sul periodo riproduttivo influiscano vari fattori, primo fra tutti l'abbondanza di cibo, quindi popolazioni stabilitesi nei pressi di attività umane (come campi coltivati), avendo cibo abbondante durante tutto l'anno, non hanno bisogno di limitare la propria stagione riproduttiva.
In ogni caso, la gestazione dura circa cinque mesi e mezzo, al termine dei quali viene dato alla luce un unico cucciolo: esso resta con la madre fino al raggiungimento della maturità sessuale, che avviene attorno ai due anni. La femmina si riproduce nuovamente solo una volta allontanatosi il cucciolo.
In cattività, la specie vive fino a 24 anni.
A causa del declino numerico della popolazione registrato negli ultimi 30 anni la IUCN red list ha classificato Colobus polykomos come specie vulnerabile [2].

Obszar występowania gerezy białobrodej jest ograniczony do pasma ciągnącego się od Gambii po Wybrzeże Kości Słoniowej.
Gereza białobroda ma smukłą budowę ciała i długi ogon. Charakterystyczne ubarwienie - białe bokobrody, broda, klatka piersiowa i puszysty ogon, reszta czarna. Długość ciała wynosi od 45 do 72 cm, ogona 52-100 cm. Kciuk jest zredukowany do niewielkiego guzka; czaszka z niewielkim przodozgryzem; owalne orbity z wąskimi grzbietami brwiowymi. Samce ważą przeciętnie około 9,90 kg, samice 8,30 kg.
Biotop: Gerezy białobrode zamieszkują gęste tropikalne lasy deszczowe o dwóch przedłużających się i wyraźnych porach suchych oraz dwóch porach wilgotnych.
Tryb życia: Prowadzą dzienny, nadrzewny tryb życia, na ziemię schodzą sporadycznie. Zwykle żyją w niewielkich grupach społecznych złożonych z 3-4 dorosłych samic, 1-3 dorosłych samców oraz młodych. W niewoli żyją maksymalnie 23,5 roku. Długość życia na wolności nie jest obecnie znana.
Pokarm: Pomimo, że przedstawiciele tego gatunku prowadzą typowo nadrzewny tryb życia, często schodzą na ziemię w poszukiwaniu pożywienia. Dieta składa się głównie z liści, w mniejszym stopniu z owoców i kwiatów.
Rozród: Gerezy białobrode dojrzałość płciową osiągają w wieku około 2 lat. Okres ciąży trwa przeciętnie 175 dni, samice rodzą średnio 1 młode co 20 miesięcy. Małe rodzą się zupełnie białe, dopiero w wieku 3 miesięcy osiągają ubarwienie charakterystyczne dla osobników dorosłych.
W ostatnim stuleciu liczebność populacji gerez białobrodych znacznie spadła w wyniku polowań i wycinki lasów.

Colobus polykomos[2][3][4] är en däggdjursart som först beskrevs av Zimmermann 1780. Colobus polykomos ingår i släktet Colobus och familjen markattartade apor.[5][6] IUCN kategoriserar arten globalt som sårbar.[1] Inga underarter finns listade.[5] Det svenska trivialnamnet västlig svartvit guereza förekommer för arten.[7]
Liksom andra arter av samma släkte har Colobus polykomos en smal kropp. Den når en kroppslängd (huvud och bål) av 45 till 72 cm och en svanslängd av 52 till 100 cm. Hanar är med en genomsnittlig vikt av 9,9 kg tyngre än honor som blir cirka 8,3 kg tunga. Tunga hanar kan väga 14 kg. Pälsen har huvudsakligen en svart färg, bara buken, svansen och skägget på kinderna är vita.[8] Ibland är en hel krans kring ansiktet och några hår på axeln vita.[9] Svansen saknar tofs vid spetsen. Artens magsäck är uppdelad i flera segment. Påfallande är tjocka svullnader på stjärten.[8]
Ungar föds med vit päls som börjar bli svart efter en månad. Artens tumme är bara en liten stubbe.[10]
Denna primat förekommer i västra Afrika från södra Senegal till västra Elfenbenskusten. Arten vistas främst i ursprungliga regnskogar och galleriskogar.[1]
En vanlig flock bildas av en till tre vuxna hanar, tre eller fyra vuxna honor och deras ungar. En tydlig hierarki finns hos hanarna. Varje flock har ett revir som är cirka 22 hektar stort men reviren överlappar varandra. När två flockar möts skriker hanarna aggressivt.[8]
Arten är aktiv på dagen och klättrar vanligen i växtligheten. Colobus polykomos kommer ibland ner till marken. Den äter främst blad samt blommor och frukter.[8]
Fortplantningen sker antingen hela året eller bara under den torra perioden. Honor kan para sig vartannat år och de är dräktiga cirka 175 dagar. Sedan föds vanligen ett enda ungdjur. Ungen bäras den första tiden omkring av modern. Cirka två år efter födelsen blir ungen könsmogen. Med människans vård kan Colobus polykomos leva 23 år eller lite längre.[8]

Colobus polykomos (Zimmermann, 1780)
Ареал Охранный статусКоролевский колобус[1], или королевский толстотел, или гвереца с мантильей или королевская гвереца[2] (лат. Colobus polykomos) — вид обезьян семейства мартышковых отряда приматов, один из видов рода Колобусы.
Королевский колобус отличается от других колобусов расположением белых отметин на шерсти. У него белые бакенбарды, грудь и хвост.[3]
Встречается в равнинных и горных дождевых лесах в районах Африки между Гамбией и Кот Д'Ивуаром.[3]
В рационе преимущественно листья, хотя также поедает цветы и фрукты. Хотя обитает на деревьях, часто добывает пищу на земле. Образует небольшие группы, состоящие из 3—4 самок, 1—3 самцов и их потомства. Каждая группа защищает свою территорию.[3]
Основные угрозы популяции — охота и разрушение среды обитания. Международный союз охраны природы присвоил этому виды охранный статус «Уязвимый» (англ. Vulnerable).[4]

서부콜로부스 (Colobus polykomos) 또는 왕콜로부스는 구세계원숭이의 일종으로, 아프리카의 감비아와 코트디부아르 사이에 길게 뻗은 지역의 저지대와 산악 우림에서 발견된다. 주로 나뭇잎을 먹지만, 또한 과일과 꽃을 먹기도 한다. 나무 위에서 사는 수목형 동물이지만 먹이는 주로 지상에서 구한다. 3 ~ 4마리의 암컷과 1 ~ 3마리의 수컷, 그리고 그들의 새끼들로 이루어진 작은 무리를 형성하며 산다. 이들 집단들은 자기 영역임을 알리는 소리를 통해 서로 일정한 거리를 유지하며 지낸다.
서부콜로부스는 몸에 얼룩얼룩한 흰 무늬가 있어서, 다른 콜로부스속(Colobus) 종들과 구별된다. 서부콜로부스는 구레나룻과 가슴, 그리고 꼬리만 하얗고, 꼬리는 타래져 있지 않다.
