Bianchi's warbler (Phylloscopus valentini) is a species of leaf warbler (family Phylloscopidae). It was formerly included in the "Old World warbler" assemblage. It is found in China, Laos, Myanmar, and Vietnam. Its natural habitats are temperate forests, subtropical or tropical moist lowland forests, and subtropical or tropical moist montane forests.
Bianchi's 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 species name honours the Russian ornithologist Valentin Lvovich Bianchi (1857–1920).

Rare
Under 5% of wildlife watchers report a Bianchi's Warbler sighting in Doi Inthanon National Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 311th most-seen of the 367 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Bianchi's Warbler in Doi Inthanon National Park on a given day, so our monthly data shows no clear season.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Bianchi's Warbler sightings with a recorded time, and about half 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 Bianchi's Warbler sightings, Doi Inthanon National Park ranks 3rd at under 5%. The best odds are in Jiuzhaigou National Park (China, about 20%) and Cuc Phuong National Park (Vietnam, about 10%).
Same genus: Seicercus
The closest relatives of the Bianchi's Warbler that you can see in Doi Inthanon National Park (genus Seicercus) are Chestnut-crowned Warbler (about 20%) and Martens's Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bianchi's Warbler is recorded against all the birds logged in Doi Inthanon National Park (16 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.
