The western woolly lemur or western avahi (Avahi occidentalis) is a species of woolly lemur native to western Madagascar, where they live in dry deciduous forests. These nocturnal animals weigh 0.7–0.9 kg (1.5–2.0 lb). It is a folivorous species.
The western woolly lemurs live in monogamous pairs together with their offspring. The Western woolly lemur mostly consumes leaves and buds that derive from around 20 different plants which have not matured and have high levels of sugars and proteins. The food is typically consumed within the time frame of two hours before dawn and two hours after dusk, in which the lemurs consume their food at the tops of trees ranging between 2 and 9 metres. During feeding time, lemurs typically settle on thinner branches unless the tree itself is too small to support the animal's weight. Most likely due to the lemur's folivorous diet, Western woolly lemurs spend large amounts of time resting in order to conserve energy.
Western woolly lemurs travel in pairs with their mate and offspring. These pairs are female-dominated and usually very peaceful. However, if conflicts do arise, they are always initiated and resolved by the female... Wikipedia →

Likely
About 60% of wildlife watchers report a Lorenz Von Liburnau’s Woolly Lemur sighting in Ankarafantsika National Park on a given day, based on 25 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 9 mammals we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
August and September
In those months about 80% of wildlife watchers report a Lorenz Von Liburnau’s Woolly Lemur in Ankarafantsika National Park on a given day, against about 20% in January and June, the lowest months. Those are among Ankarafantsika National Park's driest months, with almost no rain against 560 mm in January. February and March have too few records to rate.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Lorenz Von Liburnau’s Woolly Lemur sightings with a recorded time, and about 7 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 Lorenz Von Liburnau’s Woolly Lemur sightings: about 60% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Lorenz Von Liburnau’s Woolly Lemur is recorded against all the mammals logged in Ankarafantsika National Park (25 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.
