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 →

With luck
About 10% of wildlife watchers report a Whistler's Warbler sighting in Jim Corbett National Park on a given day, based on 212 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 154th most-seen of the 368 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
December
In that month about 20% of wildlife watchers report a Whistler's Warbler in Jim Corbett National Park on a given day, against under 5% in February and April–October, the lowest months. That is one of Jim Corbett National Park's driest months, with about 15 mm of rain against 360 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.
2nd of 6
Of the 6 parks where we can rate Whistler's Warbler sightings, Jim Corbett National Park ranks 2nd at about 10%. The best odds are in Langtang National Park (Nepal, about 20%).
GBIF citizen-science records
It is estimated from how often the Whistler's Warbler is recorded against all the birds logged in Jim Corbett National Park (212 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.
