The Annamese langur (Trachypithecus margarita) is an Old World monkey from the Colobinae subfamily. It was formerly considered a subspecies of Trachypithecus germaini until it was elevated to a separate species by Roos and Groves in 2008. Its fur is lighter in colour than that of Trachypithecus germaini. Its range includes parts of Cambodia, Laos and Vietnam. Wikipedia →

With luck
About 10% of wildlife watchers report an Annamese Langur sighting in Ho Chi Minh City on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 7th most-seen of the 7 mammals we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
May–June and December–March
In those months about 20% of wildlife watchers report an Annamese Langur in Ho Chi Minh City on a given day, against under 5% in April and July–November, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Annamese Langur sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Ho Chi Minh City, in our data
Ho Chi Minh City is the only city on Wallace's Line with enough records to rate Annamese Langur sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Annamese Langur is recorded against all the mammals logged in Ho Chi Minh City (10 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.
