Likely
About 60% of wildlife watchers report a Mountain Leaf Warbler sighting in Kinabalu Park on a given day, based on 2,023 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 247 birds 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.
March, August and October
In those months about 70% of wildlife watchers report a Mountain Leaf Warbler in Kinabalu Park on a given day, against about 50% in January and April–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.
Yes
Of the 3 parks where we can rate Mountain Leaf Warbler sightings, Kinabalu Park has the highest daily chance: about 60%. Next come Kerinci Seblat National Park (Indonesia, about 30%) and Gunung Leuser National Park (Indonesia, under 5%).
GBIF citizen-science records
It is estimated from how often the Mountain Leaf Warbler is recorded against all the birds logged in Kinabalu Park (2,023 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.
