Red-Handed Tamarin
Saguinus midas
Geographic Distribution and Habitat
The red-handed tamarin, given this name because (you guessed it) of the red hair located on its hands and feet, lives in the rainforests north of the Amazon River in the countries of Brazil, Guyana, French Guiana, Suriname, and possibly Venezuela. They are also commonly known as golden-handed tamarins and Midas tamarins. In recent years, their habitat has begun to shrink due to deforestation. As the rainforest continues to be cleared for greater human use, the range of these primates will grow smaller as a result.

What Does It Mean?
Deforestation:
The permanent cutting, clearing, and removal of trees to convert forest land for other use, such as pasture, cropland, or plantations. Pheromone: A chemical that an animal produces which changes the behavior of another animal of the same species. New World monkey: Monkeys native to Central and South America. |
Size, Weight, and Lifespan
Red-handed tamarins grow to be around 7–12 in (18–30 cm) and weigh around 14-19 oz (400–550 g). Due to their small size, their list of predators is quite vast. Animals such as wild cats, snakes, dogs, and birds of prey may make a meal out of them if given the chance. In addition to these predators, humans also pose a threat to their survival through the destruction of their habitat. In the wild, this New World primate lives to be about 10 years old, on average.

Appearance
Red-handed tamarins have predominantly black hair, which is noticeably longer around the top of their heads. A truly stunning aspect of these primates is the red hair on their hands and feet. It almost looks as if they are wearing gloves and shoes! They have claws on every digit except their big toe, which has a flattened nail characteristic of other primates. In addition to this, their thumbs are not opposable due to the lack of a saddle joint. Near their mid-chest and around their genitalia, they possess specialized scent glands, which are used to mark their territory and provide information regarding identity and sexual receptivity of individuals. There are no obvious signs of sexual dimorphism between males and females.

Diet
Red-handed tamarins are omnivorous, and enjoy a varied diet of both plants and animals. The majority of their diet consists of insects, ripe fruits, and plant exudates such as sap or gum. They also dine on spiders, other small vertebrates such as frogs and lizards, and birds’ eggs.

Behavior and Lifestyle
These primates are arboreal within their jungle home. They spend most of their time in trees leaping among the various vines and branches the rainforest provides them with. The claws on their hands and feet allow them to get the best grip on various branches and other foliage, allowing them to remain secure while traveling from tree to tree, sometimes over 50 feet above the ground. That’s a long fall without a safety harness, so it is a good thing their claws are there to help! These primates are diurnal. They are active during the day (similar to you and me) and enjoy sleeping in the safety of the treetops during nighttime (quite different from you and me).

Daily Life and Group Dynamics
Very social, the red-handed tamarin lives in groups ranging from 4 to 15 members. Unlike some other primate groups, these tamarins are led by the eldest female and the troop is comprised of predominantly male members. The groups are mixed regarding age and sex. The territory of each group is usually around 24.7 acres (10 ha), used for foraging, shelter, and raising young. There is little aggression displayed between members of the same group, even among breeding males. Similar to other matriarchial primates, there is much more evidence of cooperation and tolerance among individuals. Communication
In terms of facial expressions, red-handed tamarins are not as diverse as higher primates. They mostly communicate through series of vocalizations, but also employ scent marks during threat displays and breeding. Reproduction and Family
Breeding season typically occurs between the months of April and July. During this time, only one female will breed. They are polyandrous, with a female mating with multiple males. The reason that only one female mates during the breeding season is due to the suppression of reproductive activity within the non-dominant females. This is a result of two factors: first, the inhibitory behavior from the dominant female; and second, the loss of ovulatory capacity by the subordinate females that is caused by pheromones emitted by the dominant breeding female. Care of the young is a group responsibility, with males and females being responsible for the care of the infants when they are not being suckled by their mother. In terms of babysitting, red-handed tamarin groups are among the best! |
Fun FactsRed-handed tamarins are superb jumpers, capable of jumping 60 feet from trees to the ground. That’s quite an impressive distance! They’re able to accomplish this due in part to the fact that their remarkable joints are able to absorb the shock from their fall. Despite their small size, red-handed tamarins are territorial and more than capable of displaying aggression when threatened. They possess sharp canines as well as the claws located on their hands and feet, which are perfect for defense. When one member of the group is threatened, all members will quickly rush to aid the tamarin in distress. It’s always nice knowing your family has your back! |

Ecological Role
By carrying and eating fruit, red-handed tamarins unknowingly help plants disperse their seeds to further destinations. As a result, seeds are planted further away than if they had just been dropped to the ground. This helps forests to grow and prevents overcrowding among vegetation. These monkeys are also avid insect-eaters, helping to keep insect populations in control. Every animal contributes to the ecological balance of our world; the red-handed tamarin is no exception!

Conservation Status and Threats
The red-handed tamarins is classified as Least Concern by the International Union for Conservation of Nature (IUCN, 2015). However, the continued destruction of the tropical rainforests of South America does present a threat to the population. Although their population is considered stable, it is our job as environmental stewards to be aware of the change we cause on this Earth, and how it affects the other residents of our beautiful planet.

Conservation Efforts
Protected areas within their geographical range contribute to their continued survival rate. Areas such as the Cabo Orange National Park in Brazil, Brownsberg Nature Park in Suriname, and the Wai Wai Community-owned Conservation Area in Guyana aid the tamarin through the protection of land. These protected areas are incredibly important, so people like you and I are able to visit and see these beautiful primates in their natural habitat.
