Whistler's warbler (Phylloscopus whistleri) is a species of leaf warbler (family Phylloscopidae). It was formerly included in the "Old World warbler" assemblage. It is found in the Indian subcontinent, from the Himalayas to Myanmar. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.
Whistler'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 common name commemorates the English ornithologist Hugh Whistler (1889–1943). Wikipedia →

Possible
About 20% of wildlife watchers report a Whistler's Warbler sighting in Langtang National Park on a given day, based on 93 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 39th most-seen of the 225 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
October
In that month about 40% of wildlife watchers report a Whistler's Warbler in Langtang National Park on a given day, against about 10% in January–March and June, the lowest months. That is one of Langtang National Park's driest months, with about 65 mm of rain against 390 mm in July.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Whistler's Warbler sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Yes
Of the 6 parks where we can rate Whistler's Warbler sightings, Langtang National Park has the highest daily chance: about 20%. Next come Jim Corbett National Park (India, about 10%) and Namdapha National Park (India, about 10%).
Same genus: Seicercus
The closest relatives of the Whistler's Warbler that you can see in Langtang National Park (genus Seicercus) are Chestnut-crowned Warbler (about 10%) and Golden-spectacled Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Whistler's Warbler is recorded against all the birds logged in Langtang National Park (93 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.
