Tamarins Marmosets and Goeldi's Monkey: Callitrichidae

Callitrichids are found in most of South America and in Central America (Panama and Costa Rica).

Callitrichids occupy various habitats, including primary forests with well-developed canopies and secondary forests with dense understories. They live in open woodlands, bamboo thickets, and scrub forests, as well as forests along rivers.

Fruits, insects, and gum (a sticky substance from tree bark) make up the main diet of all callitrichids. Most also eat nectar (sweet liquid from flowering plants), lizards, tree frogs, baby birds, bird eggs, butterflies, and spiders.
