Status: Endangered

Did you know? Golden lion tamarin breeding programs in several zoos have led to successful reintroductions back to the wild.

The golden lion tamarin spends most of its time in trees, even sleeping in tree hollows and in the center of bromeliads. When active, this primate uses its long, narrow hands to reach into tree hollows to probe for insects all the while bobbing and turning its head to detect danger. Scientists have documented seventeen golden lion tamarin bird-like vocalizations—whines, clucks, trills, peeps, rasps and screeches.
