Silvery-brown Tamarin (Saguinus leucopus) lives in tropical rainforest across Northwestern South America. Its conservation status is Vulnerable.
Fascinating facts about the Silvery-brown Tamarin
- The white-footed tamarin shows a silvery brown back marked with pale streaks and a russet coloured front, while its feet and hands are white and the tail is brown, sometimes ending in a white tip. Its face is only thinly furred with white hairs and thick brown hair crowns the neck and ears. This colour pattern makes it look very similar to the cotton-top tamarin, from which it is separated by the Atrato River.
- The white-footed tamarin occupies only a relatively small area of Colombia, living in tropical dry and wet forests as well as primary and secondary forest patches. It prefers forest edges close to streams, where it can move through the canopy in small family groups. Ongoing logging, mining, agriculture and road building are destroying and fragmenting these habitats, driving population declines.
- Females of the white-footed tamarin mate with several males, a polyandrous system that ensures multiple fathers for each litter. After a gestation of 130-150 days, a female gives birth to one to three young, and the males help rear the infants, often carrying them on their backs while foraging. Two distinct birthing seasons have been recorded, one between May and June and another between October and November, allowing the species to exploit seasonal food peaks.
- Male white-footed tamarins do more than mate; they actively help raise each infant. After a female gives birth, a male frequently picks up the newborn and carries it on his back as the group moves through the canopy. This care occurs within extended family groups of four to fifteen individuals that travel together. Their quadrupedal agility lets them manoeuvre high branches while transporting the young.
- An adult male white-footed tamarin typically weighs 494 g, while a female is only marginally lighter at about 490 g. This modest body mass makes the tamarin exceptionally light for a primate, supporting its ability to leap and swing through the forest canopy. Their sharp senses and quadrupedal agility further enhance movement among branches. Such a lightweight build is characteristic of the species' arboreal lifestyle.
