Black-fronted Titi Monkey Callicebus nigrifrons

It is endemic to the Atlantic forest region of Brazil. It is arboreal and prefers the middle to upper canopy of the forest. However, it will move to the forest floor at times to forage, travel, and play. Play behavior on the forest floor has been documented between black-fronted titis and marmosets in Brazil.

Coimbra-Filho's Titi Callicebus coimbrai

Endemic to forests in the Brazilian states of Bahia and Sergipe. Their diet consists mostly of leaves, but also including various fruits. Coimbra Filho's titi generally lives in small groups consisting of three to five members.

Titi monkeys intertwine their tails to strengthen social bonds, much like grooming is known to do. Mated pairs can often be seen with their tails entwined, as well as family groups of 3 or more, as seen here.

The White-tailed Titi, Callicebus discolor (Primates - Pitheciidae), is one of the 29 recognized species of the South American titi monkeys. It is a small monkey, diurnal and arboreal. They live in groups ranging from 2 to 5 individuals, with an adult male and a female and her offspring. They are monogamous. The male helps in brood care and carries young on his back.

Callicebus discolor has one of the largest distribution ranges of all titi monkey species, occurring from central Peru to southern Colombia (Peru, Ecuador, Colombia).
