The king colobus monkey is present in lowland and montane tropical rainforests. Korstjens, A.H., E.C. King colobus monkeys eat leaves during and following the monsoons, but as drought takes hold of the forest the monkeys turn to fruits and other plant foods to survive. West Africa has two monsoons each year. There are several protected areas that maintain habitat for king colobus monkeys, including Sapo National Park in Liberia, Tai National Park in Cte dIvoire, and Tiwai Island Sanctuary in Sierra Leone. Like other colobus species, this monkey is primarily a forest animal. The 19th century exhibited searching of the C. Because they spend most of their time in the trees, it would make sense that their diet mostly consists of leaves. It survives in a range of habitats from bamboo rainforests to swamps and savannahs.

The Angolan colobus monkey is one of several black and white species and, with its sturdy body and rounded head, is typical of its genus. They are prey for many forest predators, and are threatened by hunting for the bushmeat trade, logging, and habitat destruction. When moving to a suitable resting place after landing, an individual may fight with conspecifics along the way. Distribution: Coastal region of West Africa, with a small, isolated population living in eastern Nigeria. Procolobus verus. forest biomes are dominated by trees, otherwise forest biomes can vary widely in amount of precipitation and seasonality. However, despite the slowed rate of deforestation, it is important to remember that it is still deforestation, and a far cry from a net increase, or even stability, in the acres of habitat. Behavior and Lifestyle King colobus monkeys are highly arboreal. The females maintain close spatial relationships with one another and engage in grooming behavior. These monkeys live in all types of closed forests, including montane and gallery forests. These adaptations allow the monkeys to grip branches as they climb, although reduce their ability to pluck food items. In:Bridges, E.M., I.D. Olive colobus.

The name "colobus" derives from ekolobse - a Greek word, literally meaning "he cut short" or "mutilated". Tougher leaves correlate negatively with ingestion rate (g/min) as they are costly in terms of mastication, but positively with investment (chews/g). In many regions they are extremely abundant, but, where their forest habitat has been altered by logging or fire, they are much less resilient than black-and-white colobus. Almost 90% of the original rainforests of west Africa are gone, with most of the remainder being significantly degraded and fragmented. The maximum longevity reported for this species is 23.5 years in captivity. The olive colobus (Procolobus verus) is a small monkey, weighing only 4.5 kg, with short olive-coloured fur. Gestation period lasts for 175 days, after which females give birth to a single infant, usually once every 2 years. Members of the . 2nd. If successful, this proposal could potentially save crucial habitat for the king colobus, which is entirely reliant on the rainforest. It is possible that different populations exhibit different mating systems. The Worldwide Union for Conservation of Nature has rated its conservation standing as being weak. Most African forests in which C. polykomos is found experience prolonged and pronounced dry seasons. Our editors will review what youve submitted and determine whether to revise the article. There is no distinct breeding season, although most mating probably occurs during the rainy season. The king colobus mating system is not fully understood. Save my name, email, and website in this browser for the next time I comment. As a potential prey species, the abundance of these monkeys may affect the abundance of predators.

This primate has complex sacculated stomach, but lacks pouches on its cheeks. They also tend to sleep more tightly together on nights with great visibility. [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. Some are more visible, such as the cheek pads on a male orangutan, and some are not as visible, such as cheek pouches in monkeys or a giant panda's pseudothumb. The forest habitats experiences significant dry seasons and two rainfall peaks. Large snakes might also take young animals. The International Union for Conservation of Nature has rated its conservation status as being endangered. Female aggression during intergroup interactions is largely motivated by food procurement, as reproductive success is strongly dependent on having sufficient access to food. This allows them to use bacterial fermentation to break down their food, which is typically low in nutritional value and eaten in large quantities. There are many adaptations that make the king cobra a fierce predator, including deadly venom and excellent eyesight. Territorial calling is a typical type of aggression however may also be a warning to the group of predators.

The head and body length is 45 to 72 cm and the tail length is 52 to 100 cm. Figure 1. Now I wont get into all the science that goes into the process, but to sum it up, their stomach contains a bunch of microbes that ferment and break down all those leaves which then allows their body to absorb the nutrients. Sustaining this species in captivity has principally failed and focus has been on managing the habitats to stop additional degradation and habitat destruction that might hurt the species. Further, the tail is entirely white and not tufted (Nowak, 1999). Teams not often encounter different teams of identical species however once they do, males interact in aggressive shows. Polygynandry:A mating system in which both males and females have multiple mating partners during a breeding season. One of the major threats to the population of this highly endangered species is destruction of its natural habitat for private farming, commercial agriculture as well as selective logging.

Despite their territorial nature, fighting over mates rarely occurs but there is a high infanticide rate when a male leadership role is replaced or taken over. [4] Although there is no obvious preference for tree type, they have often been observed in Antiaris toxicaria.[4]. So even though to most primates, the lack of a functional thumb would be detrimental to them, it is not to a colobus, as they dont really have a need for it.

Some evidence suggests that femalesgive birth year round, while other evidence suggests that birth takes place during the dry season. Like some other Old World monkeys, the females have very large periodic swellings around the sex organs, but, uniquely, the subadult males also develop swellings, and these exactly mimic those of the female. The rainforests of Africa have an unfortunately sordid history, being the site of the 19th century exploitation in the Belgian colony of Congo, where thousands of native people lost their lives while being forced to harvest wild rubber. The word colobus comes from the Greek wordkolobs, meaning truncated or mutilated, a reference to their absent thumbs. Colobus habitats include primary and secondary forests, riverine forests, and wooded grasslands; they are found more in higher-density logged forests than in other primary forests.
