Rare
Under 5% of wildlife watchers report a Sumatran Babbler sighting in Gunung Leuser National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 114th most-seen of the 166 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report a Sumatran Babbler in Gunung Leuser National Park on a given day, against under 5% in October to August, the lowest months. That is one of Gunung Leuser National Park's wettest months, with about 700 mm of rain against 150 mm in February.
Between 1 and 4 am
Across all the parks we cover, that three-hour window holds the most Sumatran Babbler sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
2nd of 3
Of the 3 parks where we can rate Sumatran Babbler sightings, Gunung Leuser National Park ranks 2nd at under 5%. The best odds are in Way Kambas National Park (Indonesia, about 40%).
GBIF citizen-science records
It is estimated from how often the Sumatran Babbler is recorded against all the birds logged in Gunung Leuser National Park (8 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.
