Rare
Under 5% of wildlife watchers report a Mountain Leaf Warbler sighting in Gunung Leuser National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 107th 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 30%, if each day is a fresh chance.
June, September and November
In those months about 10% of wildlife watchers report a Mountain Leaf Warbler in Gunung Leuser National Park on a given day, against under 5% in July–August, October and December–May, the lowest months.
Between 1 and 4 am
Across all the parks we cover, that three-hour window holds the most Mountain Leaf Warbler 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.
3rd of 3
Of the 3 parks where we can rate Mountain Leaf Warbler sightings, Gunung Leuser National Park ranks 3rd at under 5%. The best odds are in Kinabalu Park (Malaysia, about 60%) and Kerinci Seblat National Park (Indonesia, about 30%).
GBIF citizen-science records
It is estimated from how often the Mountain Leaf Warbler is recorded against all the birds logged in Gunung Leuser National Park (12 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.
