The golden-brown mouse lemur (Microcebus ravelobensis), also known as the (Lac) Ravelobe mouse lemur, is part of the Cheirogaleidae family, and the smallest species of lemur. It is arboreal, nocturnal and usually social. It get its name from the color of its body. Like several other mouse lemurs, like the brown mouse lemur (Microcebus rufus), it is a small primate that has a brown dorsal side and a whitish-grey for its ventral side of the body. All lemurs live in Madagascar. This species was discovered in 1994.
The island of Madagascar is located off the southeastern coast of Africa. All species of lemur are indigenous to the island. The Golden-brown mouse lemur is isolated in the forest reserve of Ankarafantsika National Park, a dry deciduous forest located in northwestern Madagascar. It shares the habitat with the gray mouse lemur (M. murinus), a sympatric species. Within the habitat that which both the golden-brown lemur and gray mouse lemur live, they occupy two very different niches showing divergent regional distribution and different population density patterns. The golden-brown mouse lemur prefers habitat areas in lower latitudes that are humid... Wikipedia →

Likely
About 40% of wildlife watchers report a Golden-brown Mouse Lemur sighting in Ankarafantsika National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 9 mammals we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
May
In that month about 60% of wildlife watchers report a Golden-brown Mouse Lemur in Ankarafantsika National Park on a given day, against about 10% in January and June–September, the lowest months. That is one of Ankarafantsika National Park's driest months, with about 5 mm of rain against 560 mm in January. February has too few records to rate.
Between 5 and 8 pm
Across all the parks we cover, that three-hour window holds the most Golden-brown Mouse Lemur 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 Ankarafantsika National Park, in our data
Ankarafantsika National Park is the only park on Wallace's Line with enough records to rate Golden-brown Mouse Lemur sightings: about 40% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Golden-brown Mouse Lemur is recorded against all the mammals logged in Ankarafantsika National Park (10 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.
