They are occasionally seen on the forest floor. The are quadrupedal, but do engage in some leaping. Diet consists of fruit, leaves and other vegetation, insects, small invertebrates, birds’ eggs and small vertebrate. They have been observed using tools in captivity. One captive animal was observed using straw to pry cockroaches out of cracks and crevices.
They are monogamous, and the male usually carries the young on his back. Social groups consist of a mated pair and their offspring. Their tails are quite long and they frequently intertwine them when sitting together. They have a wide variety of visual signals and vocalizations – according to Fleagle they are territorial and elaborate vocal duets as part of their territorial defense. Dusky titis weigh around one kilogram.
