Golden-lion tamarins (GLT’s) are squirrel-sized primates with brilliant golden fur. The common name “lion” refers to the mane on the shoulders. GLT’s live in small family groups consisting of an adult male, female and their juvenile offspring. Their vocalizations consist of trills, clucks and whines and are more reminiscent of birdcalls than monkeys. A tamarin’s diet consists primarily of insects and fruit, but they also eat spiders, snails, lizards, eggs and small birds.
