Golden Lion Tamarin
Naturally they occur in the canopies of dense humid forests in Brazil where they drink much of their water from bromeliad plants in the canopy. These tamarins are territorial and defend their area with scent markings and high-pitched squeals. Aggression includes an open mouth, an arched back, and staring. Food includes fruits, nectar, and insects but any smaller animal may be potential food. They use their long, slender fingers and hands to probe into crevices, bark, and other hiding places for insects.
They live in groups of two to eight family members consisting of a breeding pair, offspring of one or two litters and other relatives. After a gestation of about four and a half months, the female usually gives birth to twins. They cling to their mother’s fur for the first few weeks, but all members of the group will carry and care for the infants. Grooming and huddling together forms an important social function with males responsible for 70% of the grooming interactions.
Critically endangered and down to 150 individuals in the wild in 1970, intensive conservation efforts have helped the population recover. Now classified endangered species, there are about 2,500 in the wild — about a third of which are descendants of animals released from the international zoological breeding programme.
The key concern is habitat loss with only 2% of their habitat remaining in Brazil. The selective removal of large trees reduces the available roosting hollows has left them exposed to predators. A human yellow fever outbreak in 2018 infected and reduced the tamarin population by 30% in places. Scientists introduced a successful vaccination programme in 2020.
Several new populations have been re-established using tamarins bred by zoos and animals moved from unprotected wild areas. The survival rate of re-introduced animals has been encouraging, but destruction of unprotected habitat continues. Zoos globally continue to provide significant resources for the golden lion tamarin conservation programme. Our tamarins are part of the international breeding programme.
A non-for-profit has been established to help fund the conservation of the species.
