Black-handed tamarins are arboreal primates that prefer semi-deciduous forest for ease of foraging and thick growth as cover from aerial and terrestrial predators.[1] Due to deforestation in eastern Brazil, black-handed tamarins regularly rely on fragmented and disturbed secondary forest habitats.[9] Although much of the forest canopy has been destroyed, and black-handed tamarins have been seen moving through all levels of the forest, they are most active in the lower to middle (5-15m) strata of the forest.[8]
