Caquetá titi Caquetá titi The Caquetá titi, Plecturocebus caquetensis, also known as the red-bearded titi or the bushy-bearded titi, is a species of titi monkey endemic to Colombia found in the Department of Caquetá region. Taxonomically, it is a member of the ""Callicebus cupreus" group" (now "Plecturocebus cupreus"), following Shunsuke Kobayashi's "Callicebus" grouping. It was first described by Thomas Defler, Marta Bueno and Javier Garcia in 2010. It is highly endangered due to habitat fragmentation and a small population. Its fur is generally brown, with a lighter tail and chestnut-red undersides, neck and cheeks. It is similar in appearance to the ornate
Coimbra Filho's titi fragment of the population, limiting reproductive options. The species' natural geographical distribution also contributes a threat to the species. Coimbra Filho's titi only naturally occurs in the Atlantic coastal forests in northeastern Brazil. This is a relatively small area in the states of Sergipe and Bahia. Due to this small range, any disturbances to these areas pose a larger than normal threat to the species' survival. More than anything else, however, human interference is the source of many problems to Coimbra Filho's titi. The areas around and inside its habitat are being developed, including paving roads and the promotion of
