The Urubamba brown titi monkey (Plecturocebus urubambensis) is a species of titi monkey, a type of New World monkey, endemic to Peru. Populations in this species were formerly classified within the brown titi (P. brunneus), but a 2015 study found it to be a distinct, undescribed species that also belonged in a different species group of Plecturocebus from P. brunneus (the P. donacophilus group), and thus described it as P. urubambensis. The results of this study were followed by the IUCN Red List, ITIS, and American Society of Mammalogists.
This species is endemic to Peru, where it is found east of the Tambo River and west of the Urubamba, Manú, and Madre de Dios rivers. This species is not as grizzled as P. brunneus, and also has a varying amount of black on the head. Wikipedia →

With luck
About 10% of wildlife watchers report an Urubamba Brown Titi sighting in Manu National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 31st most-seen of the 42 mammals we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
January and September
In those months about 20% of wildlife watchers report an Urubamba Brown Titi in Manu National Park on a given day, against under 5% in February, April–August and December, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Urubamba Brown Titi sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Manu National Park, in our data
Manu National Park is the only park on Wallace's Line with enough records to rate Urubamba Brown Titi sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Urubamba Brown Titi is recorded against all the mammals logged in Manu National Park (9 verified sightings from 2019 to 2026), 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.
