The buffy-tufted marmoset ( Callithrix aurita ), also White ear Büschelaffe , Weißpinselaffe or White ear Seidenaffe (or each -äffchen ), a primate species from the family of marmosets (Callitrichidae).
description
Like all marmosets, yellow-bored marmosets are very small primates, they can weigh around 300 to 400 grams. Their fur is mostly black, the tail is ringed black and gray. There is a white-yellow spot on the forehead, the name-giving feature is the whitish-yellow ear tufts. The limbs are rather short, as in all marmosets there are claws instead of nails on the fingers and toes (with the exception of the big toe).
distribution and habitat
Yellow-eared marmosets live in the forests on the Atlantic coast of southeastern Brazil . Their range includes the south of Minas Gerais , the state of Rio de Janeiro and the northeastern parts of São Paulo . Their habitat are mountain forests up to 1300 meters above sea level. In the past, they probably lived in lower-lying forests, but these have now been cleared.
Lifestyle and diet
Yellow-eared marmosets, like all marmosets, are diurnal tree dwellers. You move on all fours or jumping. They live in groups of 2 to 13 animals, in which usually only one dominant female reproduces. As with all marmosets, twins are usually born, the father and the other group members participate intensively in raising the young.
In contrast to most other marmosets , the Yellow-eared marmoset feed on insects to a greater extent. Their teeth are less suitable for gnawing on tree bark for the extraction of tree sap than in the closely related species, but fungi play an important role in nutrition.
Danger
As the forests in southeastern Brazil are being cleared more than in other parts of the country, the yellow-bored marmosets are also more threatened. The IUCN estimates the population at less than 10,000 adult animals, which are also distributed over numerous areas, and lists the species as "endangered" ( vulnerable ). There are now breeding and relocation projects in some zoos.
