Golden Lion Tamarin

Brazil's golden mane in the trees — a tiny, blazing primate saved by conservation.

Endangered

Leontopithecus rosalia

Overview

Golden lion tamarins are small New World monkeys with a vivid orange mane framing a dark face. They race along Atlantic Forest branches in family groups, probing bark and bromeliads for insects and fruit.

For Brazil collectors, this is a legendary recovery card — once nearly lost, now a symbol of Atlantic Forest conservation.

Habitat

  • Atlantic Forest
  • Lowland rainforest
  • Forest corridors

Lowland Atlantic Forest fragments of Rio de Janeiro state, Brazil, needing continuous canopy corridors, tree hollows for sleeping, and diverse fruiting and insect-rich understorey.
