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 →

Rare
Under 5% of wildlife watchers report a Whistler's Warbler sighting in Kaziranga National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 310th most-seen of the 323 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 Whistler's Warbler in Kaziranga National Park on a given day, so our monthly data shows no clear season. June and July have too few records to rate.
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.
6th of 6
Of the 6 parks where we can rate Whistler's Warbler sightings, Kaziranga National Park ranks 6th at under 5%. The best odds are in Langtang National Park (Nepal, about 20%), Jim Corbett National Park (India, about 10%) and Namdapha National Park (India, about 10%).
Same family: Phylloscopidae
The closest relatives of the Whistler's Warbler that you can see in Kaziranga National Park (family Phylloscopidae, Leaf Warblers) are Yellow-browed Warbler (about 20%), Dusky Warbler (about 20%) and Greenish 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 Kaziranga National Park (6 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.
