White-eared titi prevent hunters on the land, thereby inadvertently protecting the species. It also appears that the titi monkey can cross open ground between forest fragments, and some groups can thrive in disturbed habitats near human activities. However, the fragmented habitats may prevent the establishment of new territories and decrease reproductive opportunities. Forest corridors to connect fragmented forests have been proposed as an effective means to help ensure the survival of the titi monkey. The white-eared titi is found in the Beni Biological Station Biosphere Reserve and the Amboro National Park in Bolivia and benefits from the protection these reserves provide. White-eared
Collared titi least two species in this complex. But whether the Lucifer titi, "Cheracebus lucifer", or the Colombian black-handed titi, "Cheracebus medemi", are good species from this complex is in doubt. They are probably subspecies of "Cheracebus torquatus". Nevertheless, in this treatment "C. torquatus" is used in the sense of Hershkovitz (1990) until the systematics of this species complex becomes clearer. Five adults weighed an average of 1462 g (range 1410–1722 g) with a head-body length of around 290–390 mm and a tail length of about 350–400 mm. The face has very little hair, being limited to sparse short white hairs over
