Rare
Under 5% of wildlife watchers report a Sulphur-breasted Warbler sighting in Doi Inthanon National Park on a given day, based on 102 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 206th most-seen of the 367 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.
February–March and October
In those months about 10% of wildlife watchers report a Sulphur-breasted Warbler in Doi Inthanon National Park on a given day, against under 5% in April–September and November–January, the lowest months. Those are among Doi Inthanon National Park's driest months, with about 90 mm of rain a month against 340 mm in August.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Sulphur-breasted 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.

GBIF citizen-science records
It is estimated from how often the Sulphur-breasted Warbler is recorded against all the birds logged in Doi Inthanon National Park (102 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.
