The two-colored tamarin ( Saguinus bicolor ) is a primate species from the genus Saguinus in the family of marmosets (Callitrichidae). He will also coat monkeys or Mantelaffe called, and with Mantelaffe also an African Colobus is called.
features
The fur of the two-tone tamarins is colored white on the shoulders and arms, the rest of the body is brown. The belly is reddish and the top of the tail is black in color. The black, hairless head with the large ears is striking. These animals reach a head body length of 20 to 28 centimeters, the tail is 33 to 42 centimeters long and the weight is around 430 grams. As with all marmosets, the fingers and toes (with the exception of the big toe) have claws instead of nails.
distribution and habitat
Two-colored tamarins inhabit a small area in the Amazon Basin in the Brazilian state of Amazonas . Their distribution area is north of the Amazon near the city of Manaus . Their habitat are rainforests, whereby they often stay in more densely overgrown forest edge zones.
Lifestyle and diet
These primates are diurnal forest dwellers who spend most of their lives in trees. They usually stay at a height of ten to twelve meters and move on all fours or jumping. They live in groups of three to ten animals, which are made up of a dominant female, possibly other females, one or more males and their offspring.
The diet of these animals consists mainly of fruits. They seldom ingest insects and tree sap.
Predators
The long-tailed cat is a predator and tries to lure the two-colored tamarins by imitating baby monkey calls.
Reproduction
As with all tamarins, only the dominant female of the group reproduces and mates with all males in the group, a phenomenon rare among mammals known as polyandry . Twins are usually born after a gestation period of around 140 to 150 days. The rearing of the offspring is mainly the responsibility of the males, they carry the children around and only bring them to the female to suckle. Young animals are weaned at around two to three months and sexually mature at around one and a half years.
threat
Two-colored tamarins have a very small distribution area that is increasingly restricted by deforestation. Another danger is that they are increasingly being displaced by red-hand marine animals in their habitat . The IUCN lists the species as "endangered" ( endangered ).
