Hershkovitz's titi monkey

Hershkovitz's titi monkey (Plecturocebus dubius) is a titi monkey of the family Pitheciidae found in lowland western Amazonia, with confirmed populations in Bolivia, Brazil and Peru. The American zoologist Philip Hershkovitz described it in 1988 as Callicebus dubius, and the later split of the old genus placed it in Plecturocebus. It lives in forests and swampy areas near rivers and lakes, mostly in the lower canopy, and is arboreal and diurnal, with a morning and an afternoon feeding period separated by a midday rest. It is mainly a fruit eater that falls back on leaves in lean seasons and eats seeds and insects as they come. Groups of two to seven are a monogamous pair and their offspring, the males do most of the infant carrying, and pairs defend small territories by calling and sleep with their tails twined together. It is classified as Least Concern, while deforestation, agricultural expansion, logging, road building, hunting and the pet trade threaten it.
