The white-eared titi monkey (Plecturocebus donacophilus) also known as the Bolivian titi or Bolivian gray titi, is a species of titi monkey, a type of New World monkey, from eastern Bolivia and an area of western Brazil. The species has a range that extends east from the Manique River in Beni Department, Bolivia to southern Rondônia in Brazil. The southern end of its range includes forests around the city of Santa Cruz de la Sierra.
It is a medium-sized monkey with a grey back, orange underside and distinctive white ear tufts. It has an omnivorous diet, eating fruits, other plant materials and invertebrates. It is a monogamous species and lives in small groups of two to seven members consisting of the pair and their offspring. The family group has a home range of 0.5 to 14 hectares (1.2 to 34.6 acres) and the adults have a complex vocal repertoire to maintain their territory. It is also known for its characteristic twining of tails when groups are sitting together. White-eared titis can live for more than 25 years in captivity.
The white-eared titi population has a declining trend. The decline is believed to be mainly caused by human-induced habitat loss and degradation. Despite this, the International Union for Conservation of Nature (IUCN) classified the species as being of least concern in 2008 as it has shown adaptability to habitat disturbance and is found over a wide range.

Possible
About 20% of wildlife watchers report a Bolivian Gray Titi sighting in Santa Cruz de la Sierra on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 4th most-seen of the 5 mammals we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
October
In that month about 40% of wildlife watchers report a Bolivian Gray Titi in Santa Cruz de la Sierra on a given day, against under 5% in May, July–August and November–March, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Bolivian Gray Titi sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Santa Cruz de la Sierra, in our data
Santa Cruz de la Sierra is the only city on Wallace's Line with enough records to rate Bolivian Gray Titi sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Bolivian Gray Titi is recorded against all the mammals logged in Santa Cruz de la Sierra (6 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
