Habitat

Callitrichids are mainly animals of tropical rainforests; they do, however, occupy a wide range of different habitats. Tamarins and the Amazonian marmosets are typically found in high-ground primary rainforest interspersed with patches of secondary vegetation, caused by natural disturbances (tree falls). Secondary forests provide a different spectrum of fruit and may also bear a higher abundance of insects, making them highly attractive for prey foraging. Some species may also persist in secondary forests with little or no remaining primary vegetation, and close to human settlements. Pygmy marmosets are preferably found in seasonally inundated and riverine forests. Goeldi's monkey mainly ranges in forest with dense undergrowth, such as those found in bamboo forests. Such habitat may occur in widely spaced patches, which is probably one of the reasons why groups and populations of this species may be separated from each other. Tamarins of northwestern Colombia and Central America are also found in relatively dry and semi-deciduous forests. Lion tamarins occur in coastal rainforests and in the often drier inland extensions of the Atlantic forests of eastern Brazil. Eastern Brazilian marmosets live in Atlantic coastal forests, gallery forests, and in forest patches within open habitats like the Cerrado and Caatinga (Brazil) and Chaco (Paraguay and Bolivia).
