They combine young leaves with flowers that have high levels of protein. One thing I have learned in my time working with animals is that often times, an adaptation doesnt just have one purpose or reasoning behind it. They are strictly leaf-eaters and spend most of their time in treetops, preferring to eat the tender young leaves found there. Another adaptation the giant panda has for eating bamboo is its powerful jaw muscles, which give the animal its distinctive round face. Currently, this species is classified as Vulnerable (VU) on the IUCN Red List. A large number of small mammals, birds, reptiles, and predators like the jaguar inhabit this layer.

Recent work on four Rhinopithecus species, including the GSM, shows that these colobines possess derived genetic adaptations associated with an efficient ability to metabolize fatty acids and xenobiotics and to enable the digestion of high levels of RNA derived from their stomach microbiome.

When this food is not available, they will eat the stalks of older leaves, flowers and seeds. As a potential prey species, the abundance of these monkeys may affect the abundance of predators. When separate groups encounter one another, males engage in aggressive displays. When a Diana monkey gives an alarm call to warn others of an approaching predator, the olive colobus monkeys freeze, their grey-green fur making them hard to spot among the leaves. .

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. Many parts of the king colobuss range are extremely vulnerable to desertification. The best-known species is the Abyssinian colobus, or mantled guereza (C. guereza), of the East African mountains, including Mount Kenya and Kilimanjaro.
