Gestation period lasts for 175 days, after which females give birth to a single infant, usually once every 2 years. They use branches as trampolines, jumping up and down on them to get liftoff for leaps of up to 15 meters (50 feet). Because the king colobus does not successfully thrive in degraded habitat and relies on primary forest, a rainforest doesnt necessarily need to be clear-cut to be rendered unsuitable for the species, only degraded. Though it is arboreal, it eats primarily on the ground. Head and body length range from 450 to 720 mm, tail length from 520 to 1,000 mm. Colobus monkeys are capable of eating toxic foliage.

Devon Landes (author), University of Michigan-Ann Arbor, Phil Myers (editor), Museum of Zoology, University of Michigan-Ann Arbor. Teams not often encounter different teams of identical species however once they do, males interact in aggressive shows.
It is thought that the swellings allow young males to remain in the troop without being evicted by adult males, as their so-called perineal organ is lost with maturity. Possible explanations to this are, increasing inclusive fitness or maternal practice which will benefit future offspring. Colobines are folivorous, though their diet may be supplemented with flowers, fruits and the occasional insect.
This primate has complex sacculated stomach, but lacks pouches on its cheeks. Females, on average, produce 1 offspring every 20 months (Nowak, 1999) and reach sexual maturity at approximately 2 years of age.

The mother is very protective to her baby, suckling, protecting and grooming the young. ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe. Colobus groups typically have a daily foraging path of only about 500 meters. The main cause for the decline is hunting which is threatening and fragmenting populations. [7], Colobuses live in territorial groups that vary in both size (3-15 individuals) and structure. 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.

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. Unfortunately, much of the land where monsoon forest grows is also ideal for farming, which is why much of the king cololubuss forest habitat has been cleared to make way for fields. Colobus guereza is a heavy bodied animal with a long tail. Alarm calls are also sounded when a predator is threatening the group. It lives in small teams of lower than four females and 1 to three males. If you Ah, Valentines Day. Their numbers are so low as to have little to no effect on humans whatsoever. The head and body length is 45 to 72 cm and the tail length is 52 to 100 cm. They sleep in trees near a food source, which may serve to save energy. 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. So how are colobus able to do it? This article will give an overview of king colobus monkey facts, behavior, characteristics, scientific name, tropical rainforest, and IUCN. AWF works with pastoralist people to develop appropriate sustainable solutions for agricultural and settlement growth by providing training on best practices and incentivizing conservation when appropriate, like in the Congo where we provided pastoralists with increased seed varieties and new planting techniques. Colobus polykomos is considered to be highly endangered because of habitat destruction and hunting. It also has white epaulettes and white cheeks, throat and brow. [4] Although there is no obvious preference for tree type, they have often been observed in Antiaris toxicaria.[4].

ADW: Colobus polykomos: INFORMATION - Animal Diversity Web Colobinae. If successful, this proposal could potentially save crucial habitat for the king colobus, which is entirely reliant on the rainforest. In addition, their reliance on leafy vegetations, fruits and seeds, may affect the plant community, especially by dispersing seeds. A female reproduces every two years or so. This Old World monkey exhibits a prominent skull and a small rounded projection instead of the thumb. offspring are produced in more than one group (litters, clutches, etc.) Because of this, colobus are going to spend more time resting than most monkeys do. This species is otherwise called the 'western black-and-white colobus' due to the black overall coloration of its body, contrasting with white colored chest and whiskers. A large number of small mammals, birds, reptiles, and predators like the jaguar inhabit this layer. Wetland plants also need to remain stable in the soil if they deal with fast moving water that ebbs and flows. 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 females maintain close spatial relationships with one another and engage in grooming behavior. Further, the tail is entirely white and not tufted (Nowak, 1999). They are diurnal herbivores. The principle trigger for the decline is searching which is threatening and fragmenting populations. Leaves are obviously very easily ripped off branches. They spend around half their time eating leafy greens and the other half eating seeds and fruits. Nijssen, and R. No. And if you didnt know, humans and monkeys digestive systems are not designed to digest that many leaves every day. Within these landscapes, the type of land use surrounding remnant forests influences the ability of arboreal non-flying wildlife to travel, disperse and ultimately survive, making arboreal species disproportionally impacted from habitat change. It lives in small groups consisting of 3 to 4 females and 1 to 3 males, plus their young. 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.

Tail: 24 3/4 - 35 1/2 in (63 - 90 cm). Tougher leaves correlate negatively with ingestion rate (g/min) as they are costly in terms of mastication, but positively with investment (chews/g). The primary threat to the survival of the species is uncontrolled hunting for bushmeat and their pelts throughout their range, coupled with forest loss, degradation, and fragmentation. 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.
