The Sunda warbler (Phylloscopus grammiceps) is a species of Old World warbler in the family Phylloscopidae. It is found only in Indonesia. The Sunda warbler was previously placed in the genus Seicercus. A molecular phylogenetic study published in 2018 found that neither Phylloscopus nor Seicercus were monophyletic. In the subsequent reorganization the two genera were merged into Phylloscopus which has priority under the rules of the International Commission on Zoological Nomenclature. Wikipedia →

Likely
About 40% of wildlife watchers report a Sunda Warbler sighting in Kerinci Seblat National Park on a given day, based on 248 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 14th most-seen of the 203 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
May and July
In those months about 50% of wildlife watchers report a Sunda Warbler in Kerinci Seblat National Park on a given day, against about 30% in April, June, August and October, the lowest months. January has too few records to rate.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Sunda 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.
Only Kerinci Seblat National Park, in our data
Kerinci Seblat National Park is the only park on Wallace's Line with enough records to rate Sunda Warbler sightings: about 40% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Sunda Warbler is recorded against all the birds logged in Kerinci Seblat National Park (248 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.
