 Emperor TamarinEcology

    Habitat

    several levels of tropical rain forest trees.

    Niche

    Like many species of tamarin, Saguinus spends about 3O percent of its forage time searching for animal prey. It travels from one level of forest to another, feeding on insects, fruits, buds and young leaves, small vertebrates, bird eggs and tree sap or gum. Diurnal, vocal, usually found in family groups. Home range 25-100 acres, depending upon food supply and if range is shared with another species of tamarin. Range marking includes urine scent marking, bird-like calls, display and when neccesary, chasing intruders.

Life History

    Gestation about 5 mo; male parent and other group members assist in carrying the two young, transferring them to the mother at feeding time. once the young can eat food items, group members will also surrender food to them. Young ride on adults' backs until 6-7 wks, gradually increasing time spent away from security of an adult. Maturity occurs at about 15 mo. Life span in captivity to 17 yrs.

Special Adaptations

  • Elaborate moustache assists in display and in species identification.
  • Claws help keep foothold on tree branches as the monkey runs along the branch surface.
  • Small size allows animal to hide in foliage or in tree hollows when danger threatens.
  • Extended family groups help young adults learn how to raise offspring.
