Bespoke Tanzania Safaris

The Patas Monkey (Erythrocebus patas), known for its speed and terrestrial lifestyle, is found across sub-Saharan Africa, with Tanzania hosting a segment of its population. In Tanzania, they are referred to generally as “Mapepe” in Swahili, a term for monkeys, although there isn’t a specific name for this species. Tanzania’s diverse ecosystems, from the savannahs of the Serengeti to the semi-arid regions of the south, provide suitable habitats for Patas Monkeys, particularly in the northern parts of the country where grasslands and open woodlands predominate.

Population data for Patas Monkeys in Tanzania are not well-documented due to their elusive nature and the vast areas they roam. However, they are considered to have stable populations within their range. The IUCN Red List classifies them as “Least Concern,” indicating that while they are not currently at risk of extinction, they face threats from habitat loss, poaching, and human expansion. In Tanzania, conservation efforts for Patas Monkeys are part of broader wildlife management strategies, focusing on habitat preservation, reducing human-wildlife conflict, and enhancing understanding of their ecology through research. Organizations like the Tanzania Wildlife Research Institute (TAWIRI) might conduct studies that indirectly benefit Patas Monkeys by focusing on the health of savannah ecosystems where they live.

COMMON NAME: Patas Monkey

SWAHILI NAME:(Kima, though this is a general term for monkeys; no specific Swahili name known for Patas)

SCIENTIFIC NAME: Erythrocebus patas

TYPE: Mammal (Primate)

FOOD: Patas Monkeys are omnivorous, with a diet that includes:

• Fruits
• Seeds
• Leaves
• Flowers
• Insects (especially grasshoppers and termites)
• Occasionally small vertebrates like lizards

Their diet is quite varied, reflecting their adaptability to different food sources.

HABITAT: They prefer:

• Savannahs
• Grasslands
• Open Woodlands
• Acacia Scrub
• Semi-arid Regions

They are highly terrestrial, spending more time on the ground than many other monkeys.

SIZE:

• Length: Body length is about 50 to 70 cm for males (excluding tail), with tails adding another 50 to 70 cm. Females are slightly smaller.
• Height: Standing on all fours, males reach about 40 to 50 cm at the shoulder, females slightly less.

AVERAGE LIFE SPAN IN THE NATURAL HABITAT: In the wild, they can live up to 20 years, though this can vary due to predation, disease, and environmental factors.

ACTIVE: They are diurnal, most active during the day, with a preference for morning and late afternoon for foraging and socializing. They are known for their speed, being the fastest primates.

GESTATION PERIOD: The gestation period for Patas Monkeys is around 5 to 6 months (approximately 167 days).

SEXUAL DIMORPHISM: There is significant sexual dimorphism:

• Males are larger than females, with longer canines and a more robust build.
• Males have white whiskers and a white underbelly, contrasting with their reddish coat, which is less pronounced in females.

WEIGHT:

• Male: Can weigh between 7 to 13 kg (15.4 to 28.6 lbs).
• Female: Typically weighs between 4 to 7 kg (8.8 to 15.4 lbs).

SIZE COMPARISON TO A 6-FT MAN:

• Height: On all fours, a male Patas Monkey would reach about the knees of a 6-foot man. When standing on hind legs, they might reach to the waist.
• Length: Stretched out, including the tail, they would be similar in length from a man’s waist to just below his knees.

The Unique Habitat of the Patas Monkey:

Geographic Distribution:

The Patas monkey, scientifically known as Erythrocebus patas, is native to the wide expanse of sub-Saharan Africa. Its range spans from Senegal in West Africa to Sudan and Ethiopia in the east. This adaptable primate species thrives in various habitats, including open savannas, grasslands, and woodland areas, where it can find a diverse array of food sources and suitable shelter.

Adaptations for Life on the Ground:

1. Long Limbs and Agile Running:

The Patas monkey is renowned as the fastest primate, thanks to its long limbs and extraordinary running abilities. Its elongated hind limbs and strong thigh muscles enable it to reach remarkable speeds, clocking up to 35 miles per hour (56 kilometers per hour). This exceptional adaptation allows the Patas monkey to efficiently traverse the open savannas and evade predators.

2. Heat Adaptations:

Living in predominantly arid and hot environments, the Patas monkey has developed physiological adaptations to cope with high temperatures. It possesses a reduced body size and long, slender limbs that facilitate heat dissipation. Its thin, short fur helps to keep the body cool, reflecting the intense sunlight of its habitat.

Physical Characteristics and Social Behavior:

Patas Monkeys are distinctive in their appearance:

• Size: Males are significantly larger than females, with body lengths of 50 to 70 cm, not including the tail, which can add another 50 to 70 cm. Females are slightly smaller.
• Fur: Their fur is reddish-brown to grey, with white underparts, particularly noticeable in males who also have white whiskers or moustaches.
• Face: They have a dark face, with males having more pronounced facial features, including white sideburns.
• Limbs: Long, slender limbs built for speed; they are adapted for running rather than climbing, though they can climb trees for rest or escape.
• Tail: Long and used for balance, often held in an arch when running.

Striking Features:

The Patas monkey boasts distinctive physical features that make it easily recognizable. It has a lean and athletic build, with a body length of around 60 to 85 centimeters and a tail that can be as long as the body itself. Its fur color varies from reddish-brown to a sandy or golden hue, providing effective camouflage within the grassy savannas. The Patas monkey’s face is adorned with a white moustache-like marking and a prominent brow ridge, lending it a unique and captivating appearance.

Social Structure and Communication:

Patas monkeys are highly social animals that live in multi-male, multi-female groups. These groups can consist of up to 60 individuals, but usually range between 20 to 40 members. Within these groups, intricate social dynamics exist, with individuals forming strong bonds and engaging in grooming, vocalizations, and other forms of communication. Vocalizations such as barks, grunts, and chirps serve as a means of maintaining group cohesion, expressing dominance, and alerting others to potential dangers.

Feeding Habits and Diet:

Varied Diet:

The Patas monkey is an omnivorous primate with a flexible diet. It primarily feeds on a variety of plant materials, including grasses, leaves, seeds, and fruits. During the dry season when food resources are scarce, it can resort to consuming insects, small vertebrates, and even bird eggs. This dietary versatility enables the Patas monkey to adapt to the ever-changing conditions of its environment.

Foraging Strategies:

Patas monkeys employ various foraging strategies to obtain their food. They are primarily ground-dwelling, spending a significant amount of time foraging on the savanna floor. Their nimble fingers are adept at plucking grass blades and collecting fallen fruits. They are also known to use rocks or other objects as tools to crack open hard-shelled nuts or gain access to food sources.

Conservation Status and Importance:

Conservation Concerns:

The Patas monkey faces several challenges to its survival in the wild. Habitat loss due to expanding agriculture, human encroachment, and infrastructure development threatens their populations. The conversion of natural habitats into agricultural lands disrupts their foraging areas and reduces available resources. Additionally, the Patas monkey is hunted for bushmeat and captured for the pet trade, further impacting its populations.

Conservation Efforts:

Conservation organizations, researchers, and local communities are actively engaged in efforts to protect the Patas monkey and its habitat. Initiatives include the establishment of protected areas, community-based conservation programs, and raising awareness about the importance of conserving this unique primate species. By promoting sustainable land-use practices, supporting anti-poaching measures, and engaging local communities, conservationists strive to secure a future for the Patas monkey.
