Monkeys are primates, a group of mammals that also includes apes, lemurs, lorises, and tarsiers. They are found in a wide range of habitats throughout the world, from tropical rainforests to deserts. Monkeys are typically arboreal, meaning they live in trees, but some species are semi-terrestrial or terrestrial. They are highly social animals, living in groups called troops. Different species of monkeys have different characteristics, such as size, coloration, and diet. Some common types of monkeys include macaques, capuchin monkeys, and baboons.
Meat Eating Monkeys
Some species of monkeys, known as omnivores, do eat meat as part of their diet. The proportion of meat in their diet varies depending on the species and the availability of food in their environment. For example, the black howler monkey, native to Central and South America, primarily eats leaves, flowers, and fruits but also consumes insects, spiders, and small vertebrates like lizards and birds.
Other monkey species which have been observed to eat meat include:
- The Gelada, also known as the “bleeding-heart monkey”, native to Ethiopia, primarily eats grasses but also eats insects, worms, and small mammals.
- The Mandrill, native to Africa, eats fruit, leaves, flowers, and seeds as well as insects, snails, and small mammals like rodents.
- The Macaques, a group of primates found throughout Asia, are opportunistic feeders and eat a wide variety of foods, including fruits, seeds, nuts, insects, and small mammals.
However, it’s important to note that not all monkeys are meat eaters and the majority of monkey species in the wild are primarily herbivorous and eat mostly fruits, leaves, flowers, and seeds.

The Black Howler Monkey

The black howler monkey, also known as the “Alouatta pigra,” is a species of howler monkey that is native to Central and South America. They are found in Belize, Guatemala, Honduras, and southern Mexico. They are known for their distinctive black fur and loud vocalizations.
Black howler monkeys are arboreal and primarily live in tropical rainforests, but can also be found in dry and deciduous forests. They are diurnal and live in groups of up to 20 individuals, with one dominant male and several females. They are highly territorial and mark their territory with their loud vocalizations.
In terms of diet, black howler monkeys are primarily folivorous, meaning they eat mostly leaves, but also consume fruits, flowers, and insects. They have been observed eating a wide variety of plant species, and also eat small vertebrates such as lizards and birds.
Black howler monkeys are considered endangered due to habitat loss and hunting. Populations have been declining due to the destruction of their natural habitat for agriculture, logging, and urban development. Efforts are being made to protect and conserve the remaining black howler monkey populations through habitat restoration and protection.

The Gelada

The gelada, also known as the “bleeding-heart monkey” or “gelada baboon,” is a species of Old World monkey that is native to the Ethiopian Highlands. They are the only living species of the genus Theropithecus and are found only in this region of Africa.
Geladas are terrestrial and primarily live on the grasslands and alpine meadows of the Ethiopian Highlands. They are diurnal and live in large, complex social groups of up to several hundred individuals. They are highly gregarious and spend most of their time foraging for food and resting.
In terms of diet, geladas are primarily graminivorous, meaning they eat mostly grasses. However, they also eat other plants, insects, worms, and small mammals. The geladas have unique teeth structures and digestive systems which allow them to feed on tough grasses and leaves.
Geladas have distinctive, thick fur which ranges in color from dark brown to light gray, and a distinct patch of bare skin on their chest that can range in color from pink to dark purple, which is why they are sometimes referred to as “bleeding-heart monkeys.”
Geladas are considered endangered due to habitat loss and human activities such as agriculture, overgrazing, and poaching. Populations have declined in recent years due to the destruction of their natural habitat and efforts are being made to protect and conserve the remaining gelada populations through habitat restoration and protection.
Final Thoughts
In conclusion, while not all monkeys eat meat, some species such as the black howler monkey, the gelada, and the mandrill have been observed to consume small amounts of meat as part of their diet. These species are omnivorous and eat a wide variety of foods including fruits, leaves, flowers, seeds, insects, and small mammals.
It’s important to note that the proportion of meat in their diet varies depending on the species and the availability of food in their environment. And in the wild, the majority of monkey species are primarily herbivorous and eat mostly fruits, leaves, flowers, and seeds.
Habitat loss and human activities such as agriculture, overgrazing, and poaching, are major threats to the survival of these species. Efforts are being made to protect and conserve the remaining populations through habitat restoration and protection.
