The yellow-breasted warbler (Phylloscopus montis) is a species of Old World warbler in the family Phylloscopidae. It is found in Indonesia, Malaysia, and Palawan Island in the Philippines. The species is most common on the islands of Sumatra and Borneo in Indonesia. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.
The species nests in mid-February and breeds February–April. It builds domed nests with a side entrance out of grasses and bryophytes. Nests are found among roots under the overhanging lip of an eroded bank or other similar place. It forages for food alone or with small parties of not more than five birds.
The yellow-breasted 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.
The yellow-breasted warbler has a large range and a steady population size. From the perspective of conservation biology, this species is classified as one of least concern, meaning it does not appear to be threatened or vulnerable to extinction at the present time. Wikipedia →

Very likely
About 70% of wildlife watchers report a Yellow-breasted Warbler sighting in Kinabalu Park on a given day, based on 2,104 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 247 birds we can rate there. Over three days the chance rises to over 90%, if each day is a fresh chance.
March
In that month about 80% of wildlife watchers report a Yellow-breasted Warbler in Kinabalu Park on a given day, against about 50% in May and June, the lowest months.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Yellow-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.
Only Kinabalu Park, in our data
Kinabalu Park is the only park on Wallace's Line with enough records to rate Yellow-breasted Warbler sightings: about 70% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Yellow-breasted Warbler is recorded against all the birds logged in Kinabalu Park (2,104 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.
